## About the role

Dia is a browser enhanced with agentic capabilities. The agent reasons over untrusted content from the open web and takes real actions on the user's behalf, inside a client that sits next to everything the user is signed into. That combination produces a threat model that mostly doesn't have prior art — the interesting bugs aren't on a checklist, and the tooling to find them largely doesn't exist yet.

## What they're looking for

- 8+ years in offensive security — vulnerability research, exploit development, red teaming, or product security testing — with a record of finding real bugs in software other people had already reviewed
- Depth in at least one hard surface: LLM agent systems, browser or Chromium internals, OS sandboxing and native clients, or backend and cloud infrastructure — and the excitement to learn the rest
- Practical fluency using LLMs as instruments, not just as targets, plus a working sense of when their output is noise
- You write production-quality code in one or more of Go, TypeScript, Python, or Swift. You'd rather build the thing that finds a bug a thousand times than find it once
- You write findings engineers act on, and you can stay in the fix conversation and push for the durable version without owning the remediation yourself
- You thrive in a high-trust, high-ambiguity environment: you seek feedback, but you don't need hand-holding
