- Architect and implement AI agents and automation that improve the developer workflow - code review, documentation, testing, and beyond
- Drive the evaluation and integration of AI model providers, keeping a strong eye on cost, safety, and performance tradeoffs
- Serve as a scout for emerging AI capabilities - track new models, tools, and frameworks, and make recommendations to engineering leadership on when to adopt, evaluate, or pass
- Lead technical design on complex, cross-cutting projects in partnership with Security, DevEx, and infrastructure teams
- Build observability and governance tooling that gives the organization visibility into how AI tools are being used
- Operationalize AI policy and compliance requirements into our platform
