## About the role

We keep a high bar, and everything we ship has to hold up at production scale. If the whiteboard is your favorite part of engineering, you'll like it here. We don't care much about pedigree. If you took a non-traditional path or haven't used our stack, apply anyway; we'll teach you the tools. How you think about problems is the one thing we won't bend on. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- OSINT agents at the core of the product: how they plan an investigation, which sources they check, how they settle conflicting evidence, and when they decide they're done
- New data sources and tools for the enrichment engine
- Evals that tell us whether a prompt, model, or agent change made results better or just different
- Batching, caching, retries, and orchestration for jobs that enrich millions of records at a time
- Features end to end, from design doc to production
