Job description

Bitropy is building sovereign AI infrastructure for European companies - giving teams full control over data, costs, and compliance (GDPR, EU AI Act).
Our product is already live, used daily by engineering teams and CTOs, and growing fast.

👉 This is not an experiment - real product, real users, real traction.

💡 Why it’s worth it:

  • real impact from day one,

  • fast decisions, zero corporate bureaucracy,

  • small, strong, product-focused team,

  • we build things we’re genuinely proud of,

  • AI-first environment - not a buzzword, but part of daily work.

🧠 What you’ll do:

  • build and scale product features end-to-end (frontend + backend in Next.js),

  • design and develop APIs, services, and integrations,

  • work on core platform components (LLM routing, gateways, proxies),

  • shape architecture, data models, and product direction,

  • use AI in your daily workflow (agents, automation, tooling),

  • contribute to infrastructure and deployments.

🔧 Tech:

  • Next.js, TypeScript, React (fullstack - including backend in Next.js),

  • some Python where it makes sense,

  • Kubernetes (nice to have, not required),

  • Linear + Notion,

  • approach: simple, pragmatic, no overengineering.

👉 We’re AI-first and pragmatic - we pick the right tool for the job, and we’re not dogmatic about stack.

✅ Who we’re looking for:

  • strong fullstack or backend fundamentals (APIs, systems, scalability),

  • solid experience with TypeScript / React / Next.js (or strong backend + willingness to go fullstack),

  • able to deliver features end-to-end,

  • ownership mindset - you just get things done,

  • proactive, curious, eager to learn,

  • already using AI in your work (or excited to go deep on it).

Nice to have:

  • experience with Kubernetes / cloud-native,

  • experience with LLMs, agents, or AI products,

  • comfortable talking to users and understanding product needs,

  • openness to working across different stacks when needed.

🔥 How we work:

  • low on meetings, high on building,

  • fast iteration and decision-making,

  • product-first thinking,

  • we care about quality, but avoid unnecessary complexity,

  • AI is part of how we build - every day.

If you want to build a real AI product, work in an AI-first team, and have direct impact on what we ship - let’s talk.
