## About the role

The surface area is large and getting larger: a multi-tenant AI platform, a cloud estate under bank data-handling requirements, agents that read and act on customer data, and an engineering team shipping into all of it every day. Nobody can review their way across that. You build the guardrails, defaults, and tooling that scale past you. The AI attack surface. Prompt injection, tool-use abuse, exfiltration paths through agents, and the evals that tell you whether your controls hold.

## What they're looking for

- Securing LLM or agentic products in production
- Standing up a security function at a fast-growing company
- Working inside or selling into regulated financial institutions: SOC 2, GLBA, FFIEC guidance, third-party risk, exam support
