## About the role

You'll find and address security risks in AI agents and the tools and data they connect to. This is a product security role: turn attack research into tested controls that help customers deploy agents safely.

## What they're looking for

- Model agent threats. Trace how instructions, identities, permissions, and data move between agents, tools, and MCP servers
- Reproduce real attacks. Investigate prompt injection, data exfiltration, authorization failures, and unsafe tool use with clear, repeatable test cases
- Build and evaluate controls. Work with software engineers on detections, access policies, and execution isolation. Measure blocked attacks, missed attacks, and false positives
- Review product security. Assess designs and code, explain the impact of findings, and work with engineers to prioritize and verify fixes
- Make security testing repeatable. Turn findings into automated evaluations and regression tests, and document the limits of each control
- You have hands-on experience finding and fixing application, API, or cloud security weaknesses
