Work hands-on across the technology stack, including Python, Django, TypeScript, React, FastAPI, Celery, PostgreSQL, Redis, OpenSearch, AWS Bedrock, Strands Agent SDK, MCP, Terraform, and Docker, to solve complex engineering challenges and maintain platform excellence.
Design, develop, and operate agent runtime services, including spec compilation, pre-flight authorization, skills seeding, MCP tool orchestration, streaming responses, and run package recording.

At Lead and Staff levels: mentor engineers, lead technical design reviews, set engineering standards, and drive cross-team initiatives for runtime performance, MCP federation, orchestration, and multi-tenant scale.
