Job Summary
Build and lead Hadrian's offensive security function from the ground up, executing red-team operations, penetration testing, and adversary emulation across manufacturing software, robotics/OT, cloud, and physical devices.

- Proficiency building offensive tooling in Python, Go, or C/C++ and leveraging AI to accelerate offensive work

- Experience attacking or securing AI and agentic systems
