Software Engineer

🏢 Summary: Full-stack engineering role focused on building and maintaining a high-performance WYSIWYG ad designer platform using Laravel and Vue 3. The position involves developing drag-and-drop editing tools, animations, ad platform integrations, and scalable export pipelines serving high-traffic environments. Engineers work directly with stakeholders and contribute equally to new features and maintenance. 🗂️ Requirements: Experience with Laravel, Experience with Vue 3, Experience with TypeScript, Experience with PHP 8.3+, Experience with MySQL, Ability to build REST APIs, Experience with drag-and-drop UI development, Experience with performance optimization and scalability, Experience with automated testing, Ability to work across frontend and backend 📃 Skills: Laravel, Vue, TypeScript, PHP, MySQL, Vite, REST, PHPUnit, Jest, DSP, IAB 🏢 Description: You'll help us build a WYSIWYG ad designer platform - the product where drag-and-drop, layered animations and live ad-platform integrations all have to feel instant. Laravel on the backend, Vue 3 on the frontend, both yours to ship end-to-end. The creatives you help build reach roughly 200M visitors a month, so "works on my machine" stops counting pretty fast. What you'll actually do. You'll join a tight team - 3 engineers + 2 QAs - building a tool that lets people design advanced ad formats. Drag-and-drop, animations, interactive elements, real exports to real DSPs. Backend is Laravel on PHP 8.3+, frontend is Vue 3 with TypeScript and Vite, data sits in MySQL. You'll talk to the product's stakeholders directly; there's no project manager between you and the people asking for the work. The split is roughly 50/50: half your week on new features, half on keeping the older ones healthy. This is a long-term seat, not a 12-week sprint. The product's roadmap goes well past a year and we'd like you to own a slice of it. Output ends up in front of about 200M monthly visitors, so performance, query plans and asset pipelines are first-class concerns, not afterthoughts. Ship features across the stack - REST endpoints in Laravel, Vue 3 components on the editor canvas, MySQL schema and queries underneath. Build the creative-editing surface - drag-and-drop, layered animations, interactive elements - in a way that stays fast as scenes grow. Integrate with ad platforms and ad servers (IAB-style specs, DSPs, hosted exports). You design the integration; we won't gate it on RFCs. Spend about half your time on maintenance of older features: bug fixes, performance work, refactors, paying down debt before it pays you back. Own performance and scalability of the editor and the export pipeline. At 200M visitors a month, a 50ms regression is a real problem. Sit in code review for the team and write code other people enjoy reading. Tests included (PHPUnit + Jest).

🏢 Summary: Senior full-stack consultant role to lead the end-to-end build and delivery of a self-service advertising platform enabling merchants to book and monitor campaigns across Meta, Snapchat, and Adform. The engagement focuses on shipping an MVP booking and reporting flow, integrating third-party ad APIs, and designing scalable architecture for future PIM and billing extensions. Hybrid role in Stockholm, starting in August for 6 months with possible extension. 🗂️ Requirements: 5+ years software engineering experience, End-to-end product ownership (scoping, build, delivery, project management), Strong TypeScript proficiency, Strong Node.js proficiency, Full-stack development experience, Production experience with third-party API integrations, Experience with AI coding tools (Claude Code or Codex), Ability to set guardrails and review AI-generated code, Availability from August, Based in Stockholm with hybrid onsite availability, Willingness to travel to Oslo when required 📃 Skills: TypeScript, Node.js, Vue, PostgreSQL, Kubernetes, BigQuery, ClickHouse, Airflow, Meta, Snapchat, Adform, APIs, Claude, Codex 🏢 Description: Start: August Duration: 6 months + possible extension Location: Hybrid setup from Stockholm Please note: we are only looking for someone based in Stockholm. Background We need a senior full-stack consultant to lead the build of a self-service advertising platform for, where merchants book and monitor their own short-term campaigns and the system runs the ads across Meta, Snapchat, and Adform. A spec and an early prototype already exist, so the job is to make it real, ship it, and improve it over a six-month engagement. Scope of work The platform lets store merchants plan, launch, and monitor short-term campaigns themselves, with little manual work, and it needs to scale to hundreds of stores and thousands of campaigns. A merchant books a campaign through a guided form, the system creates the ads across Meta, Snapchat, and Display/Adform, and pulls performance data into a reporting dashboard. The build covers a merchant-facing booking flow, the third-party ad-platform integrations, scheduled reporting jobs, and a billing layer that reconciles booked budget against actual spend. The MVP is a working booking-and-reporting flow. PIM integration and detailed invoicing come later, so you structure the data and architecture now to support that without a rewrite. You won't start from a blank page. With a spec and an early prototype in hand, you pressure-test it with the client and the merchants, ship a first version, learn from how people use it, and improve from there. You own the engagement end to end, from scoping through the technical decisions, delivery, and project management. Ways of working and stack The work is execution-first and AI-native. We build with Claude Code and Codex against in-house skills that teach the agents our conventions, and an internal platform handles the infrastructure toil. The agents produce a lot of the code, so the value is in judgment: you set the guardrails, check the output, and decide what to build and what to cut. Our frontend runs on Vue 3 and TypeScript; backend services on Node.js over PostgreSQL, deployed to Kubernetes; data in BigQuery and ClickHouse, orchestrated with Airflow. Knowing the stack helps but isn't required. Requirements (Mandatory) You must meet all of these. Cover each one in your response. Minimum 5+ years of software engineering experience, with a track record of owning a product area end to end: scoping, build, delivery, and project management against a client who expects to see progress. Strong in TypeScript and Node.js, working across backend and frontend. Experience integrating third-party APIs in production. Work with agentic coding tools such as Claude Code or Codex, and can set guardrails and judge their output. Available from August, able to work from the Stockholm office on a hybrid basis, and open to travelling to Oslo when the work calls for it. How you work Start with the problem, not the code. You talk to users, form your own product opinions, and decide what's worth building instead of waiting for a spec. Use prototypes to think and to bring others along, getting something rough in front of people early. Have real views on where tools like Claude Code help and where they get in the way. High ownership and low ego. You drive your own work forward, push back on a spec that's wrong, and work well in a setup that's still taking shape.

🏢 Summary: Backend-heavy Fullstack Engineer role focused on building and scaling a cyber risk reporting platform used by US MSPs. The position centers on designing and owning Node/NestJS backend systems, including integrations, job queues, and data modeling, within a fast-paced product environment. You will work closely with a small, autonomous team shipping features every sprint using AI-assisted development tools. 🗂️ Requirements: Minimum 2 years commercial backend experience in Node.js or NestJS, Production experience designing schemas and writing database migrations, Hands-on experience building and debugging job queues, Experience integrating third-party APIs on the backend, Solid knowledge of TypeScript, Working experience with React, Practical experience with PostgreSQL, Practical experience with Redis, Experience using Docker, Use of AI development tools, Fluent English, Availability to work evening hours aligned with US (UTC-6) team 📃 Skills: Node.js, NestJS, TypeScript, React, PostgreSQL, Redis, Docker, BullMQ, TypeORM, Auth0, Swagger, Express, Fastify, ConnectWise, Autotask, Kaseya, Microsoft365, GoogleWorkspace 🏢 Description: We're The Digital Bunch, a cross-disciplinary digital consultancy with offices in Warsaw, Riyadh, Sydney, and London. We combine strategy, design, and technology to help companies grow. Software development is one of our core verticals, and we embed with product companies long-term as part of their engineering teams. This role is for our work on a cyber risk reporting platform. The product scans networks, endpoints, and cloud environments (Microsoft 365, Google Workspace), checks breach databases, and generates risk reports with an AI layer on top for analysis and recommendations. The reports are sold to MSPs in the US who use them to show clients where they stand on security. It's cyber tooling, nothing else. The platform has been live for 5+ years, was acquired last year by a larger company (100+ people), and is actively growing. New features ship every sprint. The codebase is mature but moves fast. You'd join a small team on our side: our CTO and one other developer. On the client side in Dallas there's a PM, QA, support, and two engineers, plus people from the parent company who rotate in when needed. Flat setup, a lot of independence. We write code with Cursor and Claude Code every day. Not as a gimmick, that's how we actually work. If you're already using AI tooling, good. If not, you'll pick it up in the first week. ⚠️ Read this first, this is a backend-heavy role Most of the interesting work lives on the server: job queues, third-party integrations, data modeling, async scans, report generation. The frontend matters, but it's not where you'll spend most of your time. If your experience is mostly React with some REST calls, this isn't the right role. We need someone who's actually built and owned Node/NestJS backends in production, schemas, queues, integrations, migrations, the whole thing. We're happy to consider someone with ~2 years of experience if those two years are genuinely backend-heavy. We're not happy to consider 6 years of frontend with a skills-list backend section. ⏰ Working hours, read this too The client team is in Dallas, Texas (UTC-6). You need to be available in the evenings: - Daily standups happen between 19:00–21:00 Polish time, 30–45 minutes - Monday planning runs at 23:00 Polish time - The rest of the day is yours. Most people work something like 12:00–20:00 or 14:00–21:00 - No weekends, no on-call If you can't do evenings, this isn't the right fit. Wanted to be upfront about that. 📌 The work You'll ship features across the full stack, weighted toward the backend: NestJS on the server, PostgreSQL and Redis underneath, React on the frontend. The backend integrates with 15+ external services (breach intelligence APIs, cloud provider APIs, PSA systems like ConnectWise), runs BullMQ job queues, and uses TypeORM and Auth0. There's always something new to wire up. About 10% of your time goes to triaging production issues reported by customers. That's engineering debugging, not answering support tickets. Small team means you have real input into what gets built and how. Nobody's handing you pixel-perfect Jira tickets. We ship behind feature flags, get it in front of users fast, and iterate. If you're the type who spends three weeks perfecting architecture before writing a line of code, this isn't your pace. First-day commits. Our CTO onboards you personally, but we expect you shipping from the start. 👉 What we're looking for - At least 2 years of commercial backend work in Node.js / NestJS (or a close equivalent, Express or Fastify with real production ownership). We'll ask about it. - You've designed schemas, written migrations, debugged queues, and integrated third-party APIs, not just consumed them from a frontend - Solid TypeScript and React. You don't need to be a CSS wizard, you need to be comfortable moving across the stack - Hands-on with PostgreSQL, Redis, Docker - You use AI tools for development (Cursor, Claude Code, Copilot, whatever works for you) - Fluent English, spoken and written. You're on daily video calls with Americans - Actually okay with working late Polish hours (see above) - Self-directed. Nobody assigns you tasks step by step 👍 Bonus points - Worked in cybersecurity, SOC/SIEM tooling, or compliance before - Know your way around BullMQ, TypeORM, Auth0, or Swagger codegen - Built integrations with PSA systems (ConnectWise, Autotask, Kaseya) or MSP-facing tooling - Worked with US-based teams or in product companies 🚫 Probably not for you if - Your CV lists React/Next/Tailwind projects and the backend section is a skills list with no project evidence - You've mostly consumed REST APIs, not built them - Your backend experience is a single side project or a bootcamp module - You want to spend most of your day on UI polish 🎉 What you get - 20,000–26,000 PLN net/month, B2B - Fully remote, or Warsaw office in central Warsaw (dogs welcome) - Long-term product work on a single platform, not project hopping - Latest hardware and tooling - Multisport card - Regular salary reviews - Referral bonuses 💃 Hiring process 1. Intro call with Alex (CTO). 15–30 min. We talk about the role, you ask questions, and we see if it makes sense for both sides. 2. Take-home task. Build a small full-stack app (React + NestJS). The NestJS side carries most of the weight. Capped at 2 hours. Use AI tools, we don't care how you get there, we care that it works and you understand it. 3. Live review. 60 min. You walk us through your code, we ask you to add a feature live (should take minutes with AI, not half an hour), then we talk architecture and how you think about systems. 4. Meet the client team. Short call with the Dallas side before we finalize.

You'll own features end-to-end — from pixel-perfect frontend work to shipping backend functionality when needed. This is not a siloed role. You'll move fast, make real decisions, and have direct impact on a product used by people who care deeply about learning and research. We don't have managers. We have engineers who own their work. TECH STACK The stack is heavily TypeScript. On the frontend: SvelteKit, Tailwind, DaisyUI, and Playwright, with DDD and CQRS patterns. On the backend: Node.js, Fastify, PostgreSQL, and queues. ML components are in Python. The stack is pragmatic, not dogmatic — tools may shift as the product evolves. WHAT WE LOOK FOR Elite communication You set accurate expectations and live up to them. No surprises, no ambiguity about status or blockers. Deep resilience Bugs, crises, tough reviews — you have a large buffer before stress impacts your output. You don't crack under pressure. No ego We're here to build something great, not to manage insecurities. The best idea wins, regardless of who had it. Product mastery You understand the engineering principles behind the best software ever made — and care deeply about the difference between good and great. Independent and obsessive by nature You go deep on everything you touch. You're a lifelong learner who can't help but care about quality. Being an ex-founder is a bonus. ENGINEERING CULTURE Optional code reviews We trust you. Merge when you're ready. Ask for a second pair of eyes when you want one. Radical autonomy We don't second-guess your decisions. You own the call. High-bandwidth collaboration Constant communication means everyone has context without formal gates or status meetings. Direct feedback Code reviews are blunt, concise, and respectful. We say what we mean. Ruthless efficiency We aggressively adopt any tool — AI included — that increases speed and leverage. Limited frontend test coverage Supplemented by strong architecture and top talent, not bureaucratic QA processes. RECRUITMENT PROCESS Recruiter screening — a short intro call to align on basics. 1-on-1 with the engineering lead — a conversation about how you think and work. Technical challenge (~4 hours) — use AI, Google, or any resource you need. We care about the result, not the method. One-month paid contract — with the possibility to extend indefinitely. Honest, frequent feedback throughout so you always know where you stand. COMPENSATION & BENEFITS Salary $100,000 – $150,000 depending on experience. Equity and profit share Core team members receive both equity and profit share as part of the compensation package. Unlimited PTO Use your own judgement — we won't count days. Steep learning curve You'll grow faster here than almost anywhere else — by design, not accident. Real ownership No managers capping your authority. You own your work end-to-end, with the full trust of the team behind you.
