Principal Astronomical Engineer (Irvine)

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.
