• Identify and prioritize friction points in the SDLC to drive agentic or process-based fixes.
• Work across any part of the codebase to solve problems as a generalist engineer.
• Apply distributed systems judgment to ensure generated code handles concurrency and scale correctly.

• Proficiency in Go, Rust, or Python with the ability to read and modify code in the others.
• Track record of decomposing complex, loosely specified problems into concrete proposals of small, shippable steps.
