System Hardware Engineer (Autonomous Flight Termination)

Rio Rancho, United States | Posted on 08/06/2026

Castelion was founded to restore America's ability to field advanced weapons at speed and scale. Inspired by the engineering urgency of the WWII and Apollo eras, we combine rapid iteration, vertical integration, and scalable manufacturing to deliver affordable, high-performance strike systems. Our mission: rebuild industrial agility to strengthen national security and outpace evolving threats.

About the Role:

We are seeking a Senior Autonomous Flight Termination System (AFTS) Hardware Engineer to design and deliver high-reliability flight safety electronics for Castelion's long-range hypersonic strike vehicles.
