Senior Product Engineer (React + TypeScript; .NET)

🏢 Summary: Product Engineer responsible for end-to-end product development in a GovTech platform, combining architecture decisions, coding, metrics and user discovery. The role covers backend and frontend development, system design, operational ownership and AI-driven product development. You co-own the product from hypothesis through production deployment and monitoring. 🗂️ Requirements: 6+ years commercial experience as Fullstack Engineer, Production experience with backend and frontend development, Experience with .NET Core / ASP.NET Core and React + TypeScript, Strong knowledge of DDD and bounded contexts, Experience designing REST or event-driven architectures, Experience with MS SQL Server, indexing and execution plans, Ability to design versioned and backward-compatible APIs, Experience with CI/CD pipelines, Knowledge of test pyramid (unit, integration, E2E), Experience with Azure cloud services, Ability to define and track product metrics (e.g. DORA), Experience with Application Insights and monitoring practices 📃 Skills: .NET, ASP.NET, EF, MediatR, MS, SQL, React, TypeScript, Redux, Zustand, Jotai, Azure, App, Service, Application, Insights, Service, Bus, CI/CD, DDD, CQRS, EventSourcing, Saga, Outbox, KQL, REST, Claude, Cursor 🏢 Description: W Publink budujemy GovTech jutra, czyli aplikacje dla Skarbników i Urzędników jednostek samorządu terytorialnego. Skracamy godziny jałowej biurokracji i oddajemy urzędnikom czas na to, co naprawdę ważne: sprawy obywateli. Wierzymy, że sektor publiczny może działać jak sprawny biznes i mieć przy tym bardziej ludzką twarz. Zaczynaliśmy jako mała grupa konsultantów, a dziś jesteśmy startupem IT/SaaS i zaczynamy skalować naszą misję. Przez ostatnie 6 lat urośliśmy z 2 do 18 mln zł ARR. Im wcześniej dołączysz, tym większy możesz mieć wpływ na to, co i jak zbudujemy dalej. Kogo szukamy? Product Engineera, który będzie naszym partnerem inżynierskim i realnym współwłaścicielem produktu, a nie wykonawcą backlogu. Kogoś, kto razem z Product Builderem prowadzi produkt od hipotezy do wartości na produkcji, łącząc rozmowę z użytkownikiem, decyzje architektoniczne, działający kod i metryki. Osoby, która widzi, jak AI zmienia paradygmat budowy produktów cyfrowych, i chce być częścią tej zmiany. To możesz być ty jeśli... Mindset produktowy Masz 6+ lat komercyjnego doświadczenia jako fullstack engineer, z backendem i frontendem produkcyjnie po obu stronach. W poprzednich rolach był_ś realnym współwłaścicielem decyzji co budujemy, nie tylko jak . Pokażesz konkretny przykład, kiedy świadomie odpuścił_ś feature, mimo presji. Każdy ważny feature ma u Ciebie metrykę sukcesu zdefiniowaną przed startem prac, wybraną jako leading indicator dla efektu biznesowego (retencja, expansion, time to value), nie tylko jako wskaźnik ruchu w UI. Dane wyciągasz samodzielnie z Amplitude i bazy produktowej, łączysz je w argument do dyskusji o priorytetach. Decyzyjność i ownership Piszesz ADR (Any Decision Record) z opcjami, kryteriami i rekomendacją zanim siądziesz do implementacji większej zmiany. To dla Ciebie standard, nie biurokracja. Twoja odpowiedzialność nie kończy się na merge'u. Idziesz z feature'em od pomysłu, przez deploy i monitoring, do rozmowy z użytkownikiem, który go używa. DORA metrics (deployment frequency, lead time, change failure rate, MTTR) traktujesz jako standard dojrzałego zespołu. Wiesz, co mierzy Twój, czego nie i co byś z tym zrobił_a. Architektura i jakość produkcyjna Tworzysz i utrzymujesz mapę bounded contexts modułu, projektujesz integracje między kontekstami (REST vs event-driven, sync vs async, eventual consistency). API projektujesz z wersjowaniem i wsteczną kompatybilnością. Migracje modułów planujesz w fazach z możliwością wycofania, nie big bangiem. DDD i bounded contexts to dla Ciebie codzienne narzędzie. Znasz archetypy rozwiązań (CQRS, Event Sourcing, saga, outbox, idempotency keys) na tyle, by je dobrać do problemu, a nie wynajdywać. Operacjonalizujesz feature od pierwszego commita: SLO/SLI, structured logging, dashboardy w Application Insights (z KQL i distributed tracing), on-call swojego obszaru, runbooki, blameless post-mortemy z konkretnymi wnioskami systemowymi. Bezpieczeństwo i regulacje (UOFP, NIS2/KSC) są częścią Twojego designu od początku, nie kontrolą po fakcie. Stack produkcyjny Backend: .NET Core / ASP.NET Core + EF Core, MediatR lub równoważny pattern command/query, MS SQL Server z umiejętnością czytania planów wykonania i świadomego indeksowania. Frontend: React + TypeScript po obu stronach, z zarządzaniem stanem (Redux, Zustand, Jotai) wybranym i uzasadnionym. Chmura: Azure (App Service, Application Insights, Service Bus). Sposób pracy i AI Pipeline CI/CD to dla Ciebie kod, który modyfikujesz samodzielnie. Test pyramid (unit, integration, E2E) ma u Ciebie jasne proporcje, które potrafisz uzasadnić wybranymi ryzykami. Feature flags, canary deployments lub dark launches to standard pracy z ryzykownymi zmianami. Pracujesz z Claude Code, Cursor lub równoważnym narzędziem codziennie. Pokażesz workflow, w którym AI realnie zmienia Twoje tempo lub jakość pracy. Na plus: Doświadczenie w GovTech, FinTech lub innej regulowanej branży (UOFP, klasyfikacja budżetowa, JPK, sprawozdawczość finansowa). Prowadzenie incydentu produkcyjnego od alarmu, przez diagnozę, do post-mortem z wnioskami systemowymi. Doświadczenie z LLM-ami w produkcie: RAG, function calling, prompt engineering produkcyjnie, ewaluacja jakości promptów. Discovery prowadzony samodzielnie: wywiady z użytkownikami, walidacja hipotez, Opportunity Solution Tree. Aktywność w community: prelekcje, OSS, blog techniczny, kontrybucje do narzędzi developerskich. Twoje pierwsze 90 dni w Publink Wdrożysz się do organizacji i jednego z naszych modułów. Dostarczysz pierwszą znaczącą zmianę end-to-end – od hipotezy z Product Builderem/Ownerem, przez ADR i kod, po metryki sukcesu na produkcji. Pomożesz nam określić ramy i rozpocząć przeprowadzanie realnej zmiany paradygmatu wytwarzania produktów, z klasycznego tria produktowego, na nową formę w oparciu o AI. Co dalej? Jesteś jednym z punktów referencyjnych w sprawach architektury platformy, nie tylko swojego modułu. Współprojektujesz produkty na styku modułów, rozwiązując decyzje cross-team bez konieczności eskalacji. Wnosisz do mapy bounded contexts i konwencji platformowych, które kierują pracą innych Product Engineerów. Współpraca z nami to: Realny wpływ na produkt i swoboda podejmowania decyzji w swoim obszarze Umowa B2B na partnerskich zasadach (widełki w przedziale 25-30k netto PLN) 26 dni w roku bez świadczenia usług, z zachowaniem uzgodnionego wynagrodzenia Elastyczny tryb współpracy: zdalnie lub hybrydowo, ze spotkaniami zespołu ok. raz w miesiącu w naszym biurze w Poznaniu lub Katowicach Sprzęt dopasowany do Twoich potrzeb, z systemem Windows lub macOS do wyboru Budżet na szkolenia i konferencje Dostęp do pakietu medycznego i karty sportowej na preferencyjnych warunkach Nasze podejście: co Ci obiecujemy Przeczytaj i sprawdź czy to Twój styl: ✅ Robisz pracę, która ma sens. Niezależnie od roli pracujesz przy produkcie, który komuś naprawdę zmienia dzień. Sens jest wpisany w to, co budujemy, nie dopisany na plakacie. ✅ Masz realny wpływ. O decyzji przesądzają rola, kompetencje i siła tego, co masz do powiedzenia, a nie miejsce w hierarchii. Nie czekasz na zgodę: rozumiejąc kontekst, po prostu działasz, a Twój wpływ jest widoczny. ✅ Bierzesz odpowiedzialność, traktujemy Cię jak dorosłego. Dostajesz autonomię i zaufanie zamiast kontroli i patrzenia na ręce. W zamian odpowiadasz za swoje decyzje i ich rezultaty, nie za „odhaczone zadanie". ✅ Nie godzisz się na „bo zawsze tak było". Wokół Ciebie są ludzie, którzy kwestionują status quo i nazywają absurd absurdem: w administracji, w branży i u nas samych. Nie po to, żeby narzekać, tylko żeby coś z tym zrobić. ✅ Otaczasz się ludźmi autentycznymi. Mówimy jak jest, sobie i Klientom. Informacja jest domyślnie dostępna, błędy nazywamy wprost, a feedback traktujemy jak coś, co się drugiej osobie po prostu należy. To kultura wymagająca i nie dla każdego. Jeśli te pięć zdań brzmi jak miejsce, w którym chcesz pracować, prawdopodobnie się dogadamy. A jeśli chcesz wiedzieć więcej, zanim zdecydujesz, zobacz nasz produkt, ludzi i sposób pracy na publink.com/kariera. Proces rekrutacji Traktujemy kandydatów tak, jak sami chcielibyśmy być traktowani. Na każdym etapie, do którego dotrzesz, dostajesz od nas informację zwrotną. 👊 I rozmowa z Mateuszem (CTO) – Czeka nas 45-60 minutowa rozmowa online . Porozmawiamy o technologii i sprawdzimy, czy pasujemy do siebie kulturowo. To też dobry moment dla Ciebie, żebyś zweryfikował_a, czy Publink to miejsce dla Ciebie. 💡 Zadanie rekrutacyjne – Jeśli pierwsza rozmowa będzie obiecująca, poprosimy Cię o wykonanie zadania. Nie szukamy jednego słusznego rozwiązania – chcemy zobaczyć Twój tok myślenia i podejście do rozwiązywania problemów. 💪 II rozmowa – Na podstawie zadania podejmiemy decyzję o zaproszeniu Cię na ok. 2-godzinne spotkanie w naszym biurze w Poznaniu lub Katowicach . Poznasz na nim osoby, z którymi będziesz na co dzień współpracować. Po tych trzech krokach albo przedstawiamy 🤝 ofertę, albo obszernie feedbackujemy cały proces. W trakcie dyskutowania oferty, za Twoją zgodą rozmawiamy z osobami, które znają Cię z wcześniejszych współprac. ☎️ Rozmowy referencyjne pomagają nam lepiej zrozumieć jak działasz i jak możemy Ci pomóc w wejściu do Publink.

🏢 Summary: B2B full-stack product engineering cooperation with a strong frontend focus, delivering user-facing hospitality software features from discovery and design through production release. The role combines VueJS-based frontend craft, daily PHP/Laravel backend work, product judgment, UX quality, and AI-augmented development in a remote-first model. 🗂️ Requirements: Strong commercial experience with TypeScript, JavaScript, VueJS, Tailwind, and Pinia, Experience with component architecture, state management, and performance, Documented backend engineering experience with PHP and Laravel, Knowledge of design patterns, APIs, caching, database query optimization, microservices, and message queues, Ability to deliver frontend and backend features end-to-end, Communicative Polish and English 📃 Skills: TypeScript, JavaScript, VueJS, Tailwind, Pinia, PHP, Laravel, Node.js, REST, Docker, GitLab, MySQL, MariaDB, MongoDB, Redis, Microservices, Kubernetes, Claude, Cursor 🏢 Description: The role This is a full-stack product engineering cooperation with a strong frontend focus. You take responsibility for technical initiatives end-to-end: from technical discovery and solution design, through implementation and testing, to release and production readiness. The Product Manager steers direction and owns the what and why. You own the how and the technical solution. Your technical home is the frontend: user journeys, component architecture, interaction design, and UX quality. You also work across the backend when practical—for example, when connecting APIs, implementing business logic, or building integrations. What you'll actually do • Deliver user-facing features end-to-end: design, build, test, and ship both the frontend and backend. • Partner with the Product Manager on technical discovery to validate feasibility, identify constraints, and shape the technical approach before scope is locked. • Own end-to-end quality and care whether the experience works in production, not only whether it passed review. • Use AI-augmented development: Claude Code is a daily driver, with MCP servers, custom agents, and internal tooling as part of the workflow. • Collaborate closely with Product Managers and backend engineers; you own the how, while the PM owns the what and why. • Maintain UX coherence by noticing recurring issues, raising them, and leaving the product better than you found it. Tech stack • Full-stack • TypeScript • JavaScript • VueJS • Node.js • Claude Code • MCP servers • AI agents • REST API • Docker • GitLab CI/CD • PHP • Laravel • MySQL / MariaDB • MongoDB • Redis • Microservices • Kubernetes What we're looking for Technical expectations: • Strong commercial experience with TypeScript, JavaScript, VueJS, Tailwind, and Pinia, including component architecture, state management, and performance. • UX sensibility: you notice problems before users complain and care about interaction quality. • Documented PHP and Laravel backend engineering experience. You understand design patterns, APIs, caching, database query optimization, microservices, and message queues. Backend development is a daily task in this full-stack role. • Hands-on experience with Claude Code, Cursor, or equivalent AI tooling is a strong plus, including generating backend integrations with AI and understanding skills, spec-driven development, and feedback loops. • Communicative Polish and English for close collaboration with PMs, QA, and software engineers. You'll enjoy collaborating with us if • You have shipped user-facing features used by real people and understand what broke and why. • You notice UI details that most engineers scroll past. • You are curious about the business reason behind a feature before building it. • You naturally take responsibility for a feature from the PM conversation through to production. • You use AI tools to move beyond the frontend boundary into full-stack work when needed. • You care about slow connections, keyboard use, and screen sizes nobody designed for. • You can assess whether a feature is worth building without needing to make the final product decision. Bonus points • You have a side project that you built, shipped, and perhaps use yourself. • You use AI tools on your own account, not only when they are provided as part of a project. • You have worked with or contributed to a design system or component library. • You have built Node.js services or backend integrations beyond the occasional CRUD endpoint. Probably not for you if • Your definition of done is a Figma-accurate implementation regardless of how it works for users. • You consider backend someone else's problem and maintain that as a firm boundary. • Your hands-on AI experience is mostly autocomplete and the occasional PR summary. Contract terms • B2B cooperation. • Monthly compensation: 15,000–25,000 PLN net, depending on experience and agreed scope of services. • Remote-first collaboration model. • International technology and product projects. • Flexible project collaboration setup. • Planned service breaks aligned with contract terms. • Opportunity to collaborate with experienced product and technology teams. • Opportunity to access selected knowledge-sharing initiatives. Recruitment process • Introductory call with the recruiter, up to 45 minutes, covering your background, what you are looking for, and mutual fit. • Technical interview with the Team Leader, Tech Lead, and Product Manager, up to 90 minutes. It includes technical questions and discussion of frontend architecture, full-stack delivery, product ownership, and practical AI use. The focus is on judgment and initiative rather than keyword recall. • Time-boxed technical task reflecting the type of services involved, reviewed together in a follow-up call. The focus is on your process, UX decisions, and how you handle work beyond the frontend.

ABOUT THE ROLE We're looking for a Senior or Staff Product Engineer with a strong track record of building intuitive, performant end-to-end product experiences. The defining quality of this role is craft — you care deeply about how things feel to use, and you're energised by the opportunity to make software feel like magic because AI is doing real work behind the scenes. You'll work directly with the CEO, Operations, AI, and Design teams to scope and ship user-facing features. There's no product manager layer here — you'll engage directly with users, iterate quickly, and own the quality of what you deliver from UI through to server-side logic.

🏢 Summary: Backend-focused Product Engineer role focused on building and owning hospitality software end-to-end, from technical discovery to production support. The position emphasizes backend architecture, distributed systems, AI-augmented development, and close collaboration with Product Managers. Engineers are expected to take ownership of technical solutions, quality, and continuous system improvement in a fully remote environment. 🗂️ Requirements: Strong commercial experience with PHP, Experience with Laravel or Symfony, Experience designing microservices and REST APIs, Knowledge of event-driven systems, Experience with MySQL or MariaDB, Experience with MongoDB, Experience with Redis, Experience with Docker, Experience with Kubernetes, Experience with GitLab CI/CD, Hands-on use of AI development tools, Communicative Polish, Communicative English, Ability to own projects end-to-end, Experience with backend architecture and distributed systems 📃 Skills: PHP, Laravel, Symfony, MySQL, MariaDB, MongoDB, Redis, Docker, Kubernetes, GitLab, CI/CD, REST, CQRS, RabbitMQ, JavaScript, TypeScript, Node.js, Claude, Cursor, Microservices, EventSourcing 🏢 Description: The ability to build software is no longer rare. AI has made execution accessible to almost everyone. What's rare now is judgment — knowing what to build, why it matters, and what it takes to see it through to real customer impact. The role At Profitroom we build hospitality software used by thousands of hotels and millions of guests. Engineers own initiatives end-to-end: from understanding the business problem, through technical discovery, implementation, release, and production. The PM steers direction. You own the technical solution — all of it. Your technical home is backend development: data models, business logic, APIs, distributed systems. You step outside it when AI and established patterns make it practical. When something genuinely exceeds your range, you recognise the call and make it — but "genuinely" is the key word. "The builder drives; the PM steers." This is what we mean when we say Product Engineer. Not a title — a way of working. What you'll own Backend services - designed, built, tested, and shipped by you Technical discovery: validate feasibility, identify constraints, and shape the approach before scope is locked End-to-end quality: merged code is the beginning, not the end- you stay on standby through hypercare AI-augmented development: Claude Code is our daily driver- MCP servers, custom agents, and internal tooling are part of the real workflow Close collaboration with Product Managers - you own the how, they own the what and why Continuous improvement: you leave systems better than you found them You'll enjoy collaborating with us if You've shipped things that survived contact with real users — and when bugs appeared, they were yours to fix You get restless when you don't understand why something is being built before you start building it Owning a problem end-to-end feels more natural than executing a fully-specified ticket AI tools feel like a natural extension of how you think and work — not something you use because someone told you to You have opinions about what quality actually means, and your answer doesn't start with "the QA team" You can explain a technical trade-off to a product manager and a business rationale to a senior engineer You ask "is this worth building at all?" before diving into how to build it Bonus points: You have a side project — something you built for yourself, for real users, or just because you had to You use AI tools on your own account, not just when your employer provides them You've built or worked with Event Sourcing / CQRS in a production system You've built an MCP server or Claude Code agent for a real workflow Probably not for you if: You're most comfortable when everything is fully specified before you start You consider testing someone else's job, or something you do after the feature is done Your hands-on AI experience is mostly autocomplete and the occasional PR summary Technical expectations PHP & Laravel / Symfony — strong commercial experience; you know the frameworks, not just the syntax Backend architecture — microservices, REST APIs, event-driven systems; you've designed things, not just implemented them Infrastructure & databases — MySQL (MariaDB), MongoDB, Redis, Docker, Kubernetes, GitLab CI/CD AI tooling — hands-on Claude Code, Cursor, or equivalent in real development; bonus if you've built MCP servers or agents Communicative Polish and English — you work closely with PMs, QA, and other engineers Tech stack PHP, Laravel, Symfony, Claude Code, MCP servers, AI agents, MySQL / MariaDB, MongoDB, Redis, CQRS, Event Sourcing, Microservices, RabbitMQ, Docker, Kubernetes, GitLab CI/CD, REST API, JavaScript, TypeScript, Node.js.
