• Concevoir et construire les surfaces de produit que les ingénieurs et les agents d'IA utilisent quotidiennement, y compris les flux de travail en libre-service dans notre portail de développeur Backstage.
• Améliorer les systèmes de construction, les pipelines CI/CD, l'infrastructure de test et l'observabilité sur lesquels toute l'organisation dépend.
• Prototyper et évaluer de nouveaux outils de développement IA à mesure qu'ils arrivent, et décider quoi adopter, configurer et étendre à l'ensemble de l'organisation d'ingénierie.
• 6+ years of industry experience in software engineering, including cross-team projects with measurable impact on engineering productivity
• A UX mindset applied to engineering systems: you think in personas, journeys, and end-to-end workflows, and design for the people and agents who use what you build
• Demonstrated experience building developer infrastructure, DevEx, or platform tools that other engineers depend on, from CDE rollouts and internal CLIs to MCP servers and build/CI at 100+ engineer scale
• Hands-on experience with agentic developer tools like Claude Code, Cursor, or Codex, and considered opinions about their limits, where they help, and how to scale their use
• Strong systems thinking: you reason about build pipelines, CI/CD, dev environments, and test infrastructure as interconnected systems, not isolated tools
• Fluency in the languages our tooling is built in: Go and Python for CLIs, services, MCP servers, and Slackbots, plus TypeScript and React for the web UIs
