## About the role

Nebula, our agentic harness, turns days of manual synthesis into minutes of analysis for analysts across the Intelligence Community and the Department of Defense. Whether that is true on a given day comes down to the intelligence layer: how agents reason, retrieve, call tools, and produce output an analyst can trust. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 2+ years of professional software engineering experience shipping production code, with strong Python. Candidates with 4+ years will be considered at the senior level
- Experience shipping at least one LLM-powered feature to real users, and knowing how you knew it worked: the eval, the metric, and what you changed because of it
- Hands-on experience with at least one of retrieval pipelines, tool use and function calling, or agent orchestration
- Experience designing evaluations for non-deterministic output and iterating on prompts, retrieval, and tooling based on what fails
- Strong software fundamentals: testing, code review, typed interfaces, and code that survives constant change
- Comfort taking a loose ask and turning it into a working feature without a fully specified ticket
