Responsibilities

- Define service boundaries, state ownership, idempotency, and retry semantics.
- Write, review, and ship production code in Node.js and TypeScript using agentic coding tools.
- Define reference patterns, including service templates, shared libraries, and code generators.
- Plan and execute incremental migrations with tested rollbacks while keeping production running.
- Build and maintain AI workflow tooling, including MCP servers, evaluation scripts, and automated checks.
- Instrument services with metrics, alerts, dashboards, and tracing, and own production incidents end to end.
- Make targeted changes in React and Angular applications when backend work requires them.
- Partner with product, growth, and engineering colleagues in code reviews and architecture discussions.
