## About the role

v0 turns natural language into working, deployed applications. An agent writes code, executes it, and ships it on a user's behalf. That makes v0 one of the most interesting and highest-stakes security surfaces at Vercel: sandboxed code execution, multi-tenant isolation, permission boundaries between what a user asked for and what the agent actually did, and resistance to prompt injection and tool misuse.

## What they're looking for

- Strong full-stack fundamentals: Comfortable in TypeScript, React, and Node, and able to work in the same codebase, PR flow, and velocity as the rest of the v0 team
- You influence through code, not just process: You'd rather fix the root cause in a PR than write a policy doc about it. You can be the security conscience of a fast-moving team without becoming its bottleneck
- Comfortable with ambiguity: v0's threat model is still being written. You're excited to define it rather than inherit a mature playbook
- Willing to build with v0, not just secure it: You're happy to actually go use v0 to build things and understand how our products work end to end, not just read the code from the outside
