Principal Astronomical Engineer

At Turion Space our astronautical engineering work is what makes autonomous operations in orbit possible. This team owns the flight dynamics navigation guidance and mission analysis that let our spacecraft maneuver rendezvous and operate safely in a contested and increasingly crowded domain. As a Principal Astronautical Engineer you'll lead the design development and implementation of astronautical engineering solutions across mission operations flight dynamics flight software and mission/systems engineering.

This is a deeply technical leadership role at the core of how Turion flies. You'll set the standard for rigor across the astronautics stack from the algorithms that determine and control spacecraft state to the software and test infrastructure that proves it works before it ever reaches orbit. Your work will directly shape the reliability of every mission we fly and the capabilities we can offer our customers. This position requires travel to our Irvine California headquarters and other locations as needed.

What We Do

Turion Space is building the infrastructure to secure and sustain the future of space. Founded to address the growing need for space domain awareness in-space servicing and debris mitigation Turion designs builds and operates spacecraft with real-world operational capability. Our vehicles are built for national security and commercial missions that require speed autonomy and resilience. We believe the next chapter of space operations will be defined by who can act not just observe. That’s why we’re focused on building platforms that move fast adapt in orbit and solve problems ranging from satellite servicing to tactical intelligence gathering. We successfully launched our DROID.001 satellite in June 2023 and DROID.002 in March 2025. DROID.003 is scheduled for launch in 2026.

Why Work With Us

Turion Space is where startup grit meets real space missions. We build and fly spacecraft for defense servicing and domain awareness. No red tape no sidelines just hands-on work that matters.
