Quick Summary

An Electric Propulsion Engineer II (Starshield) is responsible for designing and developing electric propulsion systems for spacecraft, with a focus on national security efforts.

Job Description

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

ELECTRIC PROPULSION ENGINEER II (STARSHIELD)

Starshield leverages SpaceX’s Starlink technology and launch capability to support national security efforts. While Starlink is designed for consumer and commercial use, Starshield is designed for government use, with an initial focus on earth observation, communications, and hosted payloads.
