## About the role

You'll be Rain's application security expert and the quality bar for every non-chain finding we produce. The calls are yours: what's real, how bad it is, and what has to be fixed before launch. You'll hold the line with engineers when it matters, and make the case so they agree, not just comply. Review red team findings before they reach engineers: reproduce them, cut false positives, set severity, and write tickets clear enough to fix without a meeting. Improve the scoring that grades them Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 4+ years in application security, product security, or security-minded backend engineering
- You've owned security decisions. You can tell a senior engineer their design needs to change and keep a good working relationship
- You can read an unfamiliar codebase (TypeScript/Node.js) and find the bug that matters, and you know a scary-sounding finding from a real one
- Hands-on cloud security (ideally GCP), Terraform, and edge defenses like WAFs and rate limiting
- Experience with threat models or architecture reviews. You've run tool bake-offs and dropped tools that didn't earn their cost
- You'd rather ship a check than write a document, and you use AI tools heavily without trusting them blindly
