## About the role

Design, build, and ship AI agents end to end, including conversation flows, prompts, tool and function calling, retrieval, memory, and the backend services agents depend on. Build evaluation systems (offline test suites, simulated conversations, human review loops, and production monitoring) so we know an agent is good before and after it ships. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 5+ years of professional software engineering experience, including 1+ year building and shipping LLM-powered applications in production
- Strong proficiency in Python and/or TypeScript, comfortable across backend APIs and data, with enough frontend to ship a complete feature
- Hands-on experience with prompting, tool use and function calling, RAG, structured outputs, and agent orchestration
- Experience designing evals and using data to decide what to fix next
- Product sense: you care whether the patient got their appointment booked, not just whether the model metric moved
- Clear written and verbal communication with technical and non-technical teammates
