Hiring Pitch

Wardstone is building the next generation of space-based missile defense. We design and deploy autonomous orbital interceptors capable of defeating hypersonic and ballistic threats, a capability the U.S. and its allies urgently need but that no one has yet delivered.

At Wardstone, you will build hardware that gets tested constantly and pushed to its limits, from US Air Force assisted ground experiments to supersonic ground launched platforms to future orbital prototypes. You’ll work on systems that combine advanced sensing, guidance, high-energy physics, and spaceflight in ways few organizations on Earth attempt.

We are a small, elite engineering team moving fast to solve problems of national importance. Every engineer has massive ownership, rapid iteration cycles, and a direct impact on the direction of the company and the defense of millions of people.

If you want to work at the intersection of space, autonomy, and national security, you should join Wardstone.

Tech Stack

Our first product, Hailstorm, integrates multiple advanced technologies:

  • VLEO satellite interceptors with high maneuverability and rapid response times.
  • Infrared sensing and real-time perception, enabling autonomous target detection and tracking.
  • High-impulse propulsion and high-energy dispersal systems capable of generating millisecond-scale accelerations.
  • Advanced guidance, navigation, and control (GNC) for midcourse correction and terminal homing.
  • Physics-driven simulation environments modeling orbital mechanics, missile trajectories, thermal loads, and pellet-cloud dynamics.
  • Kinetic particle-cloud intercept architecture that provides a cost-effective, scalable alternative to traditional hit-to-kill missile systems.
