Job Summary
Build and ship full-stack features using agents to maintain velocity across multiple concurrent projects. Design and deploy agentic AI systems that solve real user problems, moving from idea to production-ready implementation at speed. Perform rigorous code reviews—especially of AI-generated code—to ensure production-grade quality, security, and systems design. Set technical direction through architecture decisions, prototypes, and rapid experimentation while helping define evaluation for agent-powered features. Collaborate closely with product managers to ship, learn, and iterate.

- Strong code review skills with the judgment to maintain high quality in an AI-assisted development environment
- Strong product sense – you understand the product and what users want
- Excellent systems design – you architect for clarity, maintainability, and scale
- Bias toward action and rapid decision-making
- A doer – hands-on with code and experiments daily
- A quality gate – you care about getting it right, and you know AI-generated code needs sharp review
- Fast and intelligent – you learn fast, make smart decisions quickly, and iterate
- An AI-native builder – agentic tools are part of how you work, not an afterthought
- Experimentation-obsessed – you validate through building
