Test Engineer - Electric Propulsion, Satellites; Starlink

Space

X was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today Space

X is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

The Electric Propulsion Test Engineer is responsible for ensuring the electric thrusters that propel Starlink satellites and their associated components have been tested and qualified to function in flight conditions. Our engineers specialize in test design and execution of unique development & qualification test campaigns on an accelerated schedule.

This role offers a variety of diverse engineering challenges in a fast-paced, hands‑on environment. Electric Propulsion Test Engineers will work on state-of-the-art electric thruster technology in an unmatched, high-rate production environment. By designing and executing test campaigns for the system, you will help sustain and improve upon the largest satellite constellation in existence! Join the team and help Space

X provide global low‑latency internet and contribute to our mission of making humanity multiplanetary.
