- Build and maintain MCP servers and CLI-based agent tooling connecting agents to internal services, external model vendors, and creative asset pipelines.
- Author reusable Agent Skills and structured workflows, and define patterns for adding new ones.
- Build evaluation and observability systems, including automated evaluations, regression suites, tracing, and quality gates.
- Improve reliability, latency, and cost per successful run.
- Ship production frontend experiences with React and Next.js for agent-driven products.
- Set engineering standards, conduct architecture reviews, mentor engineers, and provide technical direction.
