Security Engineer, Full Stack

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

As a Security Engineer at Hadrian, you’ll shape the security of our platform as we expand to serve external customers and partners. You’ll drive the transition to Factory-as-a-Service, with identity, multi-tenancy, and data boundaries at the core. This is a full-stack role—spanning application code, cloud, Kubernetes, identity management, and cutting-edge operational technology on the factory floor. You’ll work with innovative systems, some being developed here for the first time, including manufacturing and OT environments that few security engineers have encountered.

Join us as a founding member of a rapidly growing security team. Instead of inheriting legacy choices, you’ll establish the standards, best practices, and tools that will scale our security from the ground up. You’ll tackle challenges end-to-end—learning unfamiliar systems and designing solutions that make secure practices the default. If you’re curious, thrive in ambiguity, and want to chart new territory, this is your opportunity to make a lasting impact.
