🏢 Summary: Senior AI-native full-stack engineer role focused on building and owning production-grade agentic systems end-to-end, from architecture to deployment and on-call. The position involves developing multi-agent workflows, RAG pipelines, and AI infrastructure, as well as delivering client-facing B2B solutions on top of an internal agent platform. Strong ownership, hands-on LLM production experience, and full-stack execution across frontend, backend, and cloud infrastructure are required. 🗂️ Requirements: 5+ years of production software engineering experience, 1-2+ years building and operating LLM systems in production, Experience deploying agentic systems with real users, Strong full-stack development experience, Hands-on experience with LLM APIs, RAG, prompt engineering, Experience with at least one agentic framework or custom orchestration, Ability to design, ship, and maintain systems end-to-end, Experience with cloud infrastructure and production deployments, Strong written English 📃 Skills: TypeScript, React, Node.js, Python, PostgreSQL, AWS, Anthropic, OpenAI, LangGraph, CrewAI, RAG, LLM, APIs, SQL, VectorDB 🏢 Description: Who we are AgentX is a platform for building and running production AI agents — and a team that ships real systems on top of it for clients who need more than a demo. The platform is the infrastructure: orchestration, memory, tools, evals, deployment — the layer that makes agentic systems actually work in production, not just in a notebook. On top of it, we build end-to-end solutions for our clients. One of the systems running on AgentX today is KsięgoBoty — a multi-agent product used daily by hundreds of Polish accounting firms. Paying customers, production load, real consequences when something breaks. We've also done to ourselves what we build for others: restructured how we work around AI tools, agent-first architectures, and a delivery model that doesn't need a Jira layer between thinking and shipping. This isn't theory — it's how we operate every day. Who we're looking for A senior engineer who owns outcomes, not tasks. This isn't a role for someone who's shipped "an LLM demo at a hackathon." We need someone who has already put agentic systems into production — with real users, real edge cases, real 2am Slack messages when something goes sideways. If you need a PM to translate the problem, a Jira board with three rounds of grooming, and acceptance criteria to tell you what "done" means — this isn't for you, and that's fine. If instead you read a Slack message like "accountants are losing 2 hours a day reconciling this" and your brain immediately jumps to "okay, what does the user actually need, what's the simplest thing that works, and how do we ship it" — keep reading. You'll own problems end-to-end. Frontend, backend, the agent layer, the deploy, the follow-up when a customer hits something weird. You decide what to build, you build it, you ship it, you watch what happens. And you get that this actually matters. On the other end of every feature there's an accountant closing books at 9pm, a firm owner trying to keep their business running. It's not just code. What "AI-native" actually means here Not "I've used ChatGPT." We mean: Claude Code / Cursor / Codex is your IDE , not a plugin you switch on when you feel like it. You know when "accept all" is safe and when it absolutely isn't. You have strong opinions on agent orchestration — when to reach for LangGraph/CrewAI/Agno vs. when to write 50 lines of plain Python that work better. You understand production reality of LLM systems — guardrails, evals, observability, retry logic, cost control, what to do when a model is non-deterministic in a way that breaks your contract with the user. You can tell when a model is the wrong tool and reach for code instead. For you, AI is a tool — not the point. What you'll actually own Agentic systems in production — multi-step workflows, RAG pipelines, agent orchestration. From architecture decision to deployment to the 3am on-call when something drifts. The AgentX platform itself — the primitives, the orchestration layer, the evals, the deployment story. You're building the thing that makes every client engagement faster and more reliable than the last. Full-stack client solutions on top of AgentX — TypeScript/React on the frontend, Python on the backend, integrated with LLM providers (Anthropic, OpenAI, others as they come). Infrastructure that holds up — Postgres, AWS, vector stores, ingestion pipelines, the unsexy layer that makes everything else possible. Quality standards for AI systems — you help us define what "good" looks like. Evals, guardrails, failure modes. Because "mostly right but wrong in scary ways" is not a feature. Our stack TypeScript, React, Node.js, Python, PostgreSQL, AWS, Anthropic + OpenAI APIs, agentic frameworks. You don't need every box ticked — you need to be the kind of specialist who picks up unfamiliar pieces quickly and confidently. What we expect (must-haves) 5+ years shipping production software , at least 1-2 of them with real LLM systems in production — not side projects, not demos Strong full-stack background — you're comfortable owning from frontend to infra, even if your center of gravity is one side AI-native coding workflow — Claude Code, Cursor, Codex, whatever — as your daily driver Hands-on with LLM APIs, RAG, prompt engineering, and at least one agentic framework (or you've built your own orchestration and have opinions on why) Strong written English — you'll communicate with clients, partners, and async teammates Ability to run a project from discovery to delivery with minimal supervision — we'll align on outcomes, you'll figure out how Nice-to-have Experience building B2B SaaS for non-technical users (SMBs, professional services) Voice agents, real-time systems (LiveKit or similar) Accounting / fintech / regulated domain exposure How we work Fast pace, but Monday to Friday. Weekends are yours. We don't do crunch, we don't do fake urgency, we don't do meetings that could've been a message. We'd rather ship steadily for years than sprint for six months and lose you. Direct line to the founder. Direct line to clients. No process layer between you and the work. Small team, real decisions, real ownership. The honest pitch Real ownership of real product areas — not a seat on a feature factory Frontier work — you're building both the platform that makes production agents work and the client systems running on top of it Compensation that reflects seniority — 14 000 – 25 000 PLN netto + VAT (B2B), with room above for someone exceptional Fully paid AI stack — Claude Max, Cursor, whatever you need to work at full speed Remote-first , flexible hours, Poland-based No filler meetings, no Jira bloat — we measure shipped systems in production, not hours logged Push back on the founder when he's wrong. He will be, regularly. How the process works 1. You send us stuff recruitment@agentx.so Your CV — yes, we read them One thing you built end-to-end you're proud of — and what you'd change about it today One AI product (yours or someone else's) you think is genuinely good, and why Your take: a client says our agent is "mostly right but wrong in ways that scare them." What do you do first? 2. We reply within 2-3 days — either "let's talk" or "not this time, here's why." No black hole. 3. We meet — 30-45 min call with the founder. We talk about your work, you ask us hard questions. If the chemistry isn't there, no hard feelings. 4. Problem-solving session (top 2-3 candidates) — we give you a real problem we're working on. You come back with how you'd approach it: your thinking, your trade-offs, your questions. We're not watching over your shoulder. We want to see how you think. 5. Decision within 2-3 days. If yes — you start when you're ready. Tomorrow, next week, after notice period. Your call.

🏢 Summary: Mid-level React/TypeScript Engineer role focused on building and owning production-grade frontend applications (dashboards, operator panels, customer apps) on top of AI agent systems. The position involves close collaboration with backend services and active use of AI coding tools while maintaining strong engineering judgment and code quality. You will take full ownership of features from design to deployment in a production environment with real users. 🗂️ Requirements: 3–5 years commercial experience in frontend development, Strong proficiency in TypeScript, Deep understanding of React and rendering lifecycle, Experience building scalable frontend architectures, Experience integrating with REST APIs and authentication systems, Ability to work with backend technologies (Node.js or Python), Experience with state management and data synchronization, Proficiency with Next.js, Experience working with MongoDB, Experience deploying or working with AWS, Ability to use AI coding tools critically and effectively 📃 Skills: TypeScript, React, Next.js, Tailwind, Node.js, Python, MongoDB, AWS, REST, Claude, Cursor, MCP 🏢 Description: Who we are AgentX is a platform for building and running production AI agents - and a team that ships real systems on top of it for clients who need more than a demo. The platform is the infrastructure: orchestration, memory, tools, evals, deployment - the layer that makes agentic systems actually work in production. On top of it, we build end-to-end solutions for our clients. One of the systems running on AgentX today is KsięgoBoty - a multi-agent product used daily by hundreds of Polish accounting firms. Paying customers, production load, real consequences when something breaks. We're small, technical, AI-heavy, and we ship. Who we're looking for A solid React engineer who actually understands what's happening under the hood, and uses AI tools daily without outsourcing their brain to them. You'll join the team that owns the user-facing layer of our products: the dashboards, the operator panels, the customer-facing apps that sit on top of the agents. We need someone we can trust to take a feature, build it well, and ship it without it coming back broken three days later. This isn't a flashy role and we're not looking for a flashy person. We need craftsmanship. If you read a ticket and your first instinct is "what's the data model, what's the component structure, where does state actually live" - keep reading. If your first instinct is "I'll just vibe-code it with Cursor and hope the PR passes" - this isn't for you, and that's fine. What we mean by "good React engineer" You write TypeScript well: types help you, they don't slow you down You understand React deeply enough to debug a re-render problem without guessing You can structure a non-trivial frontend so it doesn't turn into a tangle in six months You've worked with a real backend: REST, auth, data sync, edge cases — and you can hold both ends of a feature in your head You read other people's code carefully and review like an adult: kindly, but honestly You are comfortable using AI tools daily, but you do not outsource your judgment to them You know how to check AI-generated code instead of trusting it because it “looks right” ~3–5 years of commercial experience is roughly where we expect this person to sit. Less is fine if you're sharp; more is fine if you actually want a Mid role. How we work with AI We use AI heavily. Claude Code, Codex, Cursor, MCP, agent workflows: they're a normal part of how we work, the same way Git or Docker is. You'll be expected to use them the same way: not as a gimmick, not as a shortcut around understanding the codebase, but as leverage. That means: break work into clear chunks, guide the tools through implementation, review their output critically, fix what's wrong, and own the final result. You should be faster with these tools than without them - and you should know exactly where they're about to lie to you. AI doesn't turn a bad engineer into a good one. It just makes them ship faster, which is worse. So: We do not want people who only know how to prompt. We also do not want people who proudly refuse to use AI and treat it like autocomplete with better marketing. The right person sits in the middle: strong fundamentals, strong taste, strong ownership - multiplied by modern AI tooling. What you'll actually own Frontend, day-to-day. React, TypeScript, Tailwind, Next.js. Real product surfaces - operator dashboards, customer panels, internal tools that real people use to do real work. Fullstack when needed. You won't live exclusively in the frontend. Node/Python on the backend when a feature needs it - you don't have to be an expert, but you have to be willing. Quality. The thing you ship works, doesn't break the next thing, and doesn't make the codebase worse. We notice this. Working with the team. Code reviews, architecture decisions - we figure out the harder calls together. You're not coding in a vacuum. The stack TypeScript / React / Next.js · Tailwind · Node.js · Python (some) · MongoDB · AWS · Claude / Cursor / MCP for tooling. We don't use Go. Nice-to-have (not required) You've built a side project that you actually shipped, not just started You've worked with LLM APIs in production (not "I made a chatbot in a tutorial") You care about UX - not as a designer, but as someone who notices when something feels wrong What we offer 13 000 – 18 000 PLN netto + VAT, B2B Remote-friendly, Poland-based A small team that ships and doesn't waste your time Direct work with the founders - no Jira theater, no three-round groomings, no PM filtering your ideas Modern AI tooling fully paid for (Claude Max, Cursor, Codex, whatever helps you work better) Real ownership of the frontend layer of a product people use every day How the process works 1. You send us stuff recruitment@agentx.so Your CV — yes, we read them One thing you built end-to-end you're proud of — and what you'd change about it today One AI product (yours or someone else's) you think is genuinely good, and why Your take: a client says our agent is "mostly right but wrong in ways that scare them."

(Szukamy kogoś, kto nie lęka się hybrydy 😉 (3x w tygodniu Krakoskie biuro na Zabłociu lub Rybnicki biurowiec K1), dlatego jeśli masz daleko - nie aplikuj z nadzieją 'a nuż się uda', bo nie uda się 🙈) ✅ Masz min. 2-letnie doświadczenie jako Tester/ka oprogramowania w zakresie przeprowadzania testów manualnych, bez mrugnięcia okiem robisz analizę wymagań, tworzysz przypadki testowe, raportujesz błędy i lubisz komunikację w języku angielskim oraz polskim (min. B2)? Śmiało scrolluj dalej! ✅ Masz doświadczenie w e-commerce? Jesteś już prawie jedną nogą na naszym pokładzie! Jesteś kotem testów aplikacji mobilnych? Wal do nas od razu jak w dym, drzwiami i oknami 🙂 Musisz wiedzieć, że podczas okresu próbnego chętnie potestujemy z Tobą ramię w ramię KAŻDEGO DNIA, więc jeśli nie jesteś z Krakowa/okolic - tym razem nie porządzimy. Jeśli tylko masz otwartą głowę, myślisz nieszablonowo i zależy Ci, by działać dobrze, a nie jako tako - masz szansę stać się jednym z naszych Cyber Sailors i wesprzeć testerską załogę w creativestyle. Czujesz, że to o Tobie? Aplikuj śmiało teraz, albo płacz później 😅 ⚓️ Co Cię czeka na pokładzie creativestyle: Testowanie manualne projektów e-commerce na różnych etapach rozwoju (w wersji webowej oraz aplikacjach mobilnych), w tym m.in . testy funkcjonalne, regresyjne, wydajności, dostępności cyfrowej oraz opiniowanie użyteczności Testowanie na komputerach i nie tylko - szafka QA jest dobrze wyposażona w różne mobilne urządzenia testowe Używanie TestRail do pisania przypadków testowych i zarządzania nimi Używanie Slacka do komunikacji i przesyłania memów. W komunikacji używamy też Google Meet oraz Teams, taski ogarniamy w JIRA, a z Klientami kontaktujemy się bezpośrednio lub przez Project Managera Bezpośrednia współpraca z deweloperami i PM-ami (komunikacja w języku polskim i angielskim) ⚓️ Jesteś naszym człowiekiem, jeśli: Potrafisz celnie formułować myśli na piśmie, a pisanie instrukcji obsługi nie jest punktem, po którym stwierdzisz “ta robota nie jest dla mnie”... Posiadasz wbudowany “detektor błędów”. Szukamy dociekliwych i ciekawskich, dlatego jeśli dla zabawy szukasz dziury w całym lub szóstym zmysłem wyczuwasz, że “coś tutaj nie halo” - masz testerskie DNA! Testowanie e-commerce to twój chleb powszedni. Wiesz, że błąd w checkoucie to stan alarmowy, a niedziałający kod rabatowy potrafi złamać serce klienta szybciej niż zerwanie przez SMS. Rozumiesz, że w tym świecie każdy bug ma swoją cenę, dlatego procesy checkoutu i ścieżki zakupowe sprawdzasz z niemal detektywistyczną zaciętością. Jeśli nie masz expa w e-commerce, świat się nie zawali, ale spełnienie tego punktu sprawi, że przychylniej spojrzymy na aplikację ;-)) Bonusowe punkty do kajecika zgarniasz jeśli Magento 2, Shopware lub Shopify nie mają przed Tobą tajemnic Dodatkowo możesz nam zaimponować doświadczeniem w testowaniu natywnych aplikacji mobilnych na Android i iOS, dostępności cyfrowej, wydajności czy bezpieczeństwa. A może automatyzujesz w Playwright z TypeScriptem, ogarniasz testowanie regresji wizualnej lub AI je Ci z ręki? Potrafisz (i lubisz!) współpracować w zespole Masz doświadczenie we współpracy w metodykach zwinnych Twój smartfon nie ma przed Tobą tajemnic i biegle śmigasz po Windowsie Swobodnie komunikujesz się w języku angielskim - w mowie i piśmie. Nie potrzebujemy certów, ważne są dla nas skille Jesteś internetowym szperaczem, zakupowym freakiem, wyszukujesz najlepsze okazje, a sklepy internetowe “testujesz” od kołyski Jeśli potrafisz w 10 minut wykonać zadania takie jak: kupić na Allegro miejski czerwony rower damski Romet, podać cenę najtańszych jeansów 32x34 Diesel’a w Zalando, dowiedzieć się jaki jest ciąg dalszy wyliczanki “How much wood would a woodchuck chuck”, to na pewno się dogadamy! Znasz internet "od środka" - wiesz, jakie mamy przeglądarki, co to jest Responsive Web Design, co to jest UX i jakie są trendy Masz wyczucie estetyki, na poziomie wyższym niż dresy ortalionowe czy skarpety w sandałach XD Znasz narzędzia Jira, Confluence Cudownie, jeśli znasz język niemiecki (a jeśli nie znasz, ale zechcesz poznać - nauczymy!) Uśmiechniemy się szerzej, jeśli zdarzyło Ci się okiełznać Contentfula albo Commercetools Jeśli czytasz to ogłoszenie, ale jesteś Juniorem (ogarniętym Juniorem) i czujesz, że znasz się na powyższych zagadnieniach - aplikuj, z adnotacją "kumaty/a Junior/ka" ;-) ➡️ Co zyskasz: Twoje doświadczenie, zaangażowanie i dbałość o jakość w testach wpływają na wynagrodzenie. Jeśli masz min. 2 lata doświadczenia i znasz się na rzeczy, startujemy od 9000 PLN netto + VAT – umowa B2B. Wolisz UoP? Również jest taka opcja! Na pewno się dogadamy Ludzie i atmosfera – wiemy, że semantycznie to nie jest benefit. Ale te dwa słowa ZAWSZE padają w odpowiedzi na pytanie „Co cenisz w CS?”, więc zostawiamy to tutaj Ponad setka certyfikowanych Cyber Sailors, od których sporo się nauczysz (nawet jeśli przychodzisz z dużym doświadczeniem) Międzynarodowe klimaty Twoja ekipa wsparcia w codziennej pracy - zgrany zespół dociekliwych testerek i testerów Powietrze wolne od stresu, bardzo liberalne podejście do tego, co robimy i dużo zdrowego dystansu. Korpo to nie my. U nas docenia się pasję i samodzielność, a nie kontrolę i sztywne schematy; ufamy sobie i każdy z nas robi dokładnie to, co do niego należy. Wolność i odpowiedzialność mogą iść w parze. A jeśli sądzisz, że luz wyklucza niezawodność - udowodnimy Ci, że jest odwrotnie! BENEFITY PRACOWNICZE: Warsztaty QA Team , dzielenie się wiedzą i doświadczeniami projektowymi, szukanie nowych ścieżek testowania. Posłuchaj, co uczestnicy mówią o ostatniej edycji takich workszopów: o dniu pierwszym - tutaj , o dniu drugim - tutaj . Home office . Spokojnie - świat się nie zawali, jeśli czasem potestujesz z domu Indywidualny budżet szkoleniowy (3 000 PLN/rok siana do rozhulania) i kursy językowe. Twój rozwój = nasz rozwój Lenovo Yoga , (bo Windows muss sein!), wszystkie niezbędne peryferia i wielki monitor Medicover + Multisport Plus (Rybnik - siłownia w biurowcu K1, wystarczy wsiąść do windy; Kraków - 4 minuty spacerkiem) W biurach: konsole do gier oraz liga bilardowa/ ping-pongowa, tematyczny lunch raz w miesiącu Loftowe przestrzenie - mielimy kod w starym młynie na Zabłociu. Jest przestrzennie, komfortowo i stylowo. Mamy też rooftop! Łatwy dojazd - możesz przyjechać rowerem, przybyć na koniu, szybkim tramwajem (50), pociągiem (Kraków: Stacja Zabłocie).

Dzięki temu zbudowaliśmy pozycję lidera i zdobyliśmy liczne nagrody (np. Shop Usability Award ). W tym roku rozbiliśmy bank! Zdobyliśmy tytuł Agencji Roku plus 2 wspólne zwycięstwa z klientami: #BestCustomerExperience ( benuta ) i #BestMobileExperience ( Bergzeit ) U nas można popełniać błędy i się na nich uczyć - a także otwarcie się do nich przyznać i poprosić o wsparcie Każda osoba w firmie (łącznie z zarządem!) ma techniczny background i ogarnia internety Jesteśmy wspierani przez Copilota oraz własne narzędzie, zbudowane w oparciu o AI Używamy komercyjnych narzędzi: Slack, Jira, Confluence Komunikujemy się po angielsku, niemiecku i polsku. Ale mamy też Ślązaków - więc jak trzeba, to się i pogodo 😅 Nasi klienci pochodzą głównie z rynku DACH. Na co dzień jesteśmy z nimi w kontakcie, a bardziej złożone tematy przejmują PM-owie Dwukrotnie zostaliśmy wyróżnieni w HappyAtWork Index - niezbity dowód, że nasza piracka załoga jest zadowolona, a beczka rumu nigdy nie wysycha W creativestyle mamy 50% wolności i 50% odpowiedzialności Niezawodność, Empatia i Ciekawość (firmowe drogowskazy) prowadzą nas lepiej niż Google Maps. Zawsze wracamy do portu Co nas wyróżnia technicznie, czyli w czym wymiatamy Za co Cyber Sailors cenią creativestyle? Rozwijamy się lepiej niż tapety w Castoramie!

Jeśli zaiskrzy między nami na etapie czytania CV - zaprosimy Cię do wykonania zadania. Gdy nasze testerskie jury pomyślnie oceni rozwiązanie zadania, dział HR skontaktuje się z Tobą (krótka rozmowa telefoniczna) i jeśli znajdziesz chwilę, by przekonać nas, że chciał(a)byś wspólnie z CS-ową załogą testerów śmigać po bugach jak Ferrari po Monako, my spróbujemy przekonać Ciebie, że jesteśmy fajni i warto z nami pracować. Przygotuj się na szybki small-talk w języku Szekspira. Spotkanie face2face w biurze na Zabłociu. Sprawdzimy, czy na żywo również jest chemia. Omówimy kwestie techniczne i sprawdzimy, czy do siebie pasujemy. Decyzja Twoja i nasza, czy będziemy razem testować świat. Niezależnie od decyzji, możesz liczyć na naszą odpowiedź.

🏢 Summary: Senior backend engineering role focused on building and scaling AI-driven systems, including APIs, data pipelines, LLM orchestration, and distributed workloads on confidential production data. The position involves architecting reliable backend infrastructure for retrieval, streaming, embeddings, and integrations while ensuring security and scalability. 🗂️ Requirements: 7+ years building production backends, 6+ years of Python experience, 3+ years of FastAPI experience, 2+ years of Redis experience, Experience with PostgreSQL and SQL, Experience with distributed and async workloads, Experience with LLM systems, Knowledge of RAG or tool-calling systems, Ability to design scalable backend architectures, Experience with AI coding tools 📃 Skills: Python, FastAPI, PostgreSQL, SQL, Redis, LLM, RAG, LangChain, LlamaIndex, APIs, Embeddings, Streaming 🏢 Description: About us comm1t is a specialist IT recruitment agency delivering top engineers across Poland and Europe 🇪🇺. We combine experienced recruiters with autonomous AI agents and an obsessive focus on quality — sourcing 24/7 across LinkedIn, GitHub, and beyond to reach engineers who aren't actively job hunting but are open to the right move. We don't flood you with CVs. We get to know each candidate's skills, values, and goals, then send only the best-matched people — and we stay close through onboarding and the first months to make sure the placement lasts. About the role You'll lead the backend that drives the AI features — the APIs, the data pipelines, and the orchestration that connects the product to the language models doing the actual work. In practice that's querying across large document sets, getting trustworthy answers out of LLMs and their tool calls, pushing results to the UI as they stream, and grinding through lengthy background jobs without the whole thing toppling over. Forget CRUD. The real difficulty is making AI systems fast and reliable on confidential data, at production scale. The architecture choices land on you early, and you'll be the one living with them. What you'll do Architect and ship the APIs and services that everything else depends on Own the AI plumbing end to end: retrieval, orchestration, tool-calling, streaming, and the evals that tell you whether the results are worth anything Make async and distributed workloads rock-solid — document ingestion, embeddings, and long jobs running on Redis Wire up integrations with what clients already use (email, document stores) and harden them for real-world traffic Put data security and isolation front and center, because clients are handing over material they can't afford to leak Who you are Seven years or more delivering production backends — though how deep you go matters more to us than the figure itself You think in failure modes, not just the happy path You've shipped genuine LLM systems (RAG, tool-calling, agents), or you can't wait to — and you've got a feel for where they fall apart You lean on AI coding tools (Claude Code, Cursor, Copilot) and get real value from them: more speed, yes, but you grasp and back every line — code you'd reject in someone else's review is code you won't merge in your own A startup that keeps changing course doesn't faze you — plans get set, then torn up and redrawn Tech stack experience Python: 6+ years FastAPI: 3+ years PostgreSQL / SQL Redis: 2+ years Nice to have RAG or vector search experience LangChain or LlamaIndex
