## About the Role

Senior-level experience (5+ years) building and operating infrastructure or platform products.
Hands-on GenAI experience - you've built with LLM APIs, tool/function calling, retrieval, agents, or agent frameworks and put them into real workflows.
Modern AI coding tools (e.g., Claude Code, Codex) are part of how you work day to day.
Strong AWS fundamentals and a genuine appreciation for Infrastructure as Code and Pipeline as Code.
A real feel for developer experience - you can look at a feature and tell whether it'll make a developer's life easier or just add another thing to learn, because you've lived that friction yourself.
Strong communication and collaboration skills - you work well in a team, share your opinions clearly, and can move a topic forward with people across functions.
Solid engineering fundamentals: testing, debugging, code quality, and getting things production-ready.
Familiarity with SRE / DevOps principles and observability concepts (CloudWatch, Datadog, OpsGenie, or similar).
Proficiency in at least one language, ideally Python, Go, or TypeScript.
A bias for shipping - you're comfortable taking something ambiguous and turning it into a working solution with sensible scope.
