## About the role

Build the agent architecture that turns enterprise context into reliable action. You will design agent loops, tool-use patterns, evaluation systems, and multi-agent coordination that work on ambiguous, high-stakes operational problems rather than controlled demos. Evidence that you have shipped an agentic system beyond a prototype and improved it using production feedback or evaluations. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 4+ years building production software, including substantial hands-on work with LLM or ML-powered products
- Evidence that you have shipped an agentic system beyond a prototype and improved it using production feedback or evaluations
- Strong Python and/or TypeScript engineering, including APIs, tests, data modeling, asynchronous work, and observability
- Experience with tool calling, structured generation, retrieval, model evaluation, and multi-step workflows
- Strong judgment about when to use a model, deterministic code, a human checkpoint, or a simpler product interaction
- Comfort debugging nondeterministic behavior and reducing it to measurable, reproducible failure modes
