AI Software Engineer (F/H)

3\. Skills and experience **Must-haves :** * **Software engineering depth: 4 to 5 years minimum.** Real craftsmanship, clean design decisions, and the ability to explain the architecture trade-offs you made and why. * **Daily hands-on use of AI to build software.** Having never used AI to develop is a deal-breaker on this role. * **Comfort with ambiguity.** You move forward, decide and ship when nothing is specified in advance, and you adapt when the roadmap shifts. * **Builder mindset with evidence.** Concrete examples of things you built from zero, prototyped, tested and iterated on. **Nice-to-haves (optional) :** * **A first hands-on experience with agentic systems.** Expertise is welcome when it is real : a strong engineer with genuine curiosity and early agentic work beats a self-declared two-year agentic expert who cannot explain concretely what they built. * **A data background.** The testing logic differs from pure software: working on datasets and analysing where a system succeeds and where it fails is a plus, and it can be learned here. * **Collaborative posture.** the team will evangelise AI across the other product teams. Showing and explaining your work is expected. **Stack :** Backend: TypeScript on Deno. Frontend: Vue.js. Infrastructure: AWS with EKS, Terraform and CDKTF, plus Kubernetes for on-prem customer deployments. Observability: Honeycomb and Sentry. On the AI side: frontier models called through AWS Bedrock, with everything agentic hand-built and no framework on top. 4\.
