⭐ Mission
Join our AI Lab as a Backend Product Engineer and help accelerate Qonto's transition to an AI-first product. You'll ship user-facing AI agents that transform how 600,000+ businesses manage their finances, working in small, autonomous squads under the guidance of Sophie, our Manager for the AI Lab.
With an ambitious goal to launch one AI agent every 6 weeks, you'll own the backend and AI logic end-to-end — building reliable, maintainable systems that scale as the Lab grows.
👩💻 As a Backend Engineer for the AI Lab, you will
- Ship fast and well: Deliver a new AI agent every 6 weeks, owning the full backend and AI logic from scoping to deployment — balancing speed with reliability and minimal technical debt.
- Build for the long term: Architect pragmatic LLM guardrails and future-proof components that hold up in a regulated banking environment and don't need rewriting three months later.
- Leverage AI daily: Use AI coding tools (Cursor, Claude Code, Copilot…) for ~70% of your coding to review, refine, and ship features faster.
- Go full-stack when it counts: Contribute to frontend (React/JS) via vibe coding when needed, with the FE engineer reviewing your PRs — so the squad stays unblocked.
🏅 What we're looking for
- Python expertise: You have strong production experience in Python and know how to ship at pace — Go is a plus for integrating with Qonto's core services.
- Startup mindset: You're a fast learner and confident shipper who thrives without a tech lead to lean on — fintech or regulated industry experience is a plus.
- AI-native workflow: You use AI coding tools daily to amplify your output. Cursor or Claude Code isn't something you're trying — it's how you work.
- AI curiosity over AI expertise: Production AI experience isn't required. What matters is genuine curiosity: you follow the space, experiment on the side, and have tried building something, even just for yourself.
- Strong communication: You articulate technical decisions clearly to non-technical stakeholders and navigate cross-functional squads with ease.
🔧 What you'll get
- Unlimited access to the best AI tools on the market: Claude Code, Cursor, Copilot, Dust, Notion AI.
- A Python-first stack with hands-on AI agent work from day one — PydanticAI, LangGraph, LangChain in the mix (framework awareness appreciated; production expertise not required).
- A squad culture where autonomy is the default — minimal process, quick dailies, weekly demos with leadership, and every hour counting.
- A clear growth path: this role is designed to evolve toward full-stack and AI Software Engineer. If becoming an AI-native engineer is your ambition, this is where it happens.
🤝 About your future manager
You'll work closely with Sophie, Manager of the AI Lab — but don't expect hand-holding.
Sophie has led cross-functional teams through the full product lifecycle at both fast-growing startups and established tech companies. She partners directly with Product and Tech leadership to align the AI roadmap with Qonto's strategic goals.
Her approach: give engineers real ownership, create space for experimentation, and empower the squad to adapt their ways of working in pursuit of real impact.
💬 Hiring Process
- 2 Interviews (1 hour each): first with your Talent Acquisition Manager, and then with one of our Backend Leads
- Technical case + debrief with two Backend engineers (1 hour)
- Final interview and meeting with Sophie (1 hour)
We aim to wrap the process in 10 days max, from first interview to potential offer 🤞
If you've read this far and thought "that sounds like me but I don't check every box" — apply anyway. We hire on potential and mindset, not checklists.
