• Join our AI Lab as a Senior Backend Product Engineer and help accelerate Qonto's transition to an AI-first product. • Ship user-facing AI agents that transform how 600,000+ businesses manage their finances, working in small, autonomous squads under the guidance of our Manager for the AI Lab. • Build & 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. • Architect pragmatic LLM guardrails and future-proof components that hold up in a regulated banking environment and don't need rewriting three months later. • Use AI coding tools (Cursor, Claude Code, Copilot…) for ~70% of your coding to review, refine, and ship features faster. • Contribute to frontend (React/JS) when needed, with the front-end engineer reviewing your PRs — so the squad stays unblocked.

• Design, develop, and maintain full-stack web application features across multiple client projects. • Build scalable backend services using C# and .NET Core. • Develop responsive and maintainable frontend applications using JavaScript and React or Angular. • Integrate CMS platforms, APIs, and third-party services to support content-driven digital experiences. • Participate in technical architecture discussions and contribute to technical decision-making. • Conduct and participate in code reviews to maintain engineering quality standards. • Collaborate closely with designers, strategists, producers, and fellow engineers throughout the development lifecycle. • Ensure code quality through testing, performance optimization, and adherence to development best practices. • Work independently while proactively communicating progress, risks, blockers, and recommendations. • Maintain technical documentation and support continuous improvement initiatives across projects.
