Software Engineer (Builder Tools)

Join Hadrian, a cutting-edge technology company, as a Software Engineer on the Builder Tools team. In this role, you will build and maintain the CI/CD infrastructure, internal tooling, and AI-assisted development workflows that every engineering team at Hadrian depends on. Your work will directly impact the speed and efficiency of the company, as you will be responsible for reducing friction in the software development lifecycle and automating recurring engineering tasks. You will also have the opportunity to collaborate with application development teams and contribute to the overall improvement of engineering productivity at Hadrian.

• Construire et maintenir des bibliothèques de pipelines CI/CD qui abstraient les événements de construction, de publication et de déploiement pour une utilisation par plusieurs équipes d'ingénierie.
• Concevoir et construire des outils internes, des API et des utilitaires CLI qui réduisent la friction des développeurs et automatisent les tâches d'ingénierie récurrentes.
• Aider à rendre les systèmes internes de Hadrian prêts pour les agents de codage AI ; construire des outils de harnais, des systèmes de contexte et des boucles de rétroaction qui améliorent la qualité des contributions générées par l'IA.
• Proven ability to troubleshoot complex systems and resolve issues efficiently
• A developer empathy mindset: you build tools that are easy to adopt, well-documented, and reduce toil rather than create it
• Solid understanding of source control concepts and practical Git experience
• Strong programming fundamentals in Go, Python, TypeScript, or similar; track record of writing clean, maintainable, well-tested code
• Bachelor's degree in Computer Science or related field, or equivalent experience
• Experience with Docker and container orchestration (Kubernetes or similar)
• 5–8 years of software engineering experience, with at least 2–3 years focused on CI/CD, developer tooling, or build infrastructure
• Hands-on experience building and maintaining complex CI/CD pipelines and build infrastructure — pipeline-as-code, artifact management, multi-environment deployments
• Genuine curiosity and hands-on experience with AI coding tools and agents — Copilot, Cursor, Claude Code, or similar — and opinions about what makes them work well in a real codebase
• Experience building API-ready interfaces or harness tooling for AI coding agents
• Familiarity with GitOps principles and workflows
• Prior work on developer experience or engineering productivity programs
• Experience with static analysis, automated PR pipelines, or code review tooling
• Background in fast-paced or scaling startup environments
