Senior Infrastructure / DX Engineer (Platform)

Join our team as a Senior Infrastructure/DX Engineer (Platform) and play a key role in modernizing and consolidating our services in the cloud. You will design, build, and ship our internal developer platform, drive our cloud migration, and work closely with product engineers to solve their infrastructure problems. This is a hands-on individual-contributor role that requires strong cloud engineering experience, proficiency in TypeScript and Node.js, and a security-first instinct. Enjoy a range of benefits including 30 vacation days, flexible working hours, and a yearly learning and development budget.

• Construire et exploiter la plateforme de développement interne, la route pavée des outils et de l'infrastructure qui permet aux équipes de configurer et d'exécuter leurs propres services sans attendre.
• Conduire notre migration vers le cloud, en déplaçant et en consolidant les services dans une configuration moderne et native du cloud sans ralentir la livraison.
• Concevoir l'architecture du système et de l'infrastructure et la communiquer clairement, y compris les diagrammes que d'autres ingénieurs peuvent construire à partir de.

• A track record of building or choosing internal tooling that lets other engineers work faster, with the judgement to adopt an existing solution when one fits rather than build from scratch
• Strong, hands-on cloud engineering experience on AWS at organisational scale: multi-account setups, identity and access, networking, and account-level guardrails. Serverless is our default but we want someone who can pick the right tool for each problem
• Coding agents are part of your daily workflow, and you check their output before you rely on it. You are neither dismissive of them nor careless with them
• TypeScript on Node.js as your primary application language, or a deliberate and recent move to it. Python is a welcome secondary. Go or Rust are useful for performance-critical components
• A security-first instinct: least privilege, secrets management, and treating patching and vulnerability remediation as routine work
• Deep, hands-on experience with infrastructure as code. You have built and maintained real production estates in Terraform, or a close equivalent, and you are comfortable owning delivery pipelines on AWS
• Delivery experience in both lean startup settings and larger organisations, with ownership from start to finish. You scope a sensible first version and build on it
• We are a learning company, inside and out, and we encourage you to apply even if you do not fit all the technical requirements — all candidates are assessed based on skills, qualifications, and our business needs
• Public technical work, such as open-source contributions or writing
• A track record of building internal command-line tools or code generators
• Previous cloud-migration work
• Experience with monorepo build systems and shared tooling
