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, MECHANICAL (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.
SpaceX is hiring an Electric Propulsion Engineer to join a collaborative engineering team working on design, analysis, build, and test of flight-qualified satellite electric propulsion systems for in-space constellations. In this role you will contribute end-to-end hardware ownership—from design through production support and qualification—for propulsion systems that must meet demanding flight reliability requirements through iterative design, test, and refinement.
RESPONSIBILITIES:
- Design, analyze, test, and provide operational support for high-volume production spacecraft electric propulsion hardware
- Partner with manufacturing to ensure designs enable efficient, reliable, high-rate production
- Design, build, modify, operate, and troubleshoot electric propulsion test facilities, including vacuum chambers, pressure systems, cryogenic pumps, data acquisition and control systems, and associated instrumentation
- Analyze and review test data with numerical tools to confirm hardware is operating as expected and inform design decisions
- Lead root-cause investigations and component redesigns to improve reliability and/or production rates
- Develop and execute qualification test plans for flight readiness (vibration, shock, thermal cycle, life cycle, fault injection)
- Make rigorous, risk-informed trades across cost, lead time, reliability, and performance to meet program reliability targets for mission-critical flight hardware
- Own critical spaceflight hardware end-to-end, with support from manufacturing, reliability, test, and operations teams
- Work as an integrated team, with daily interactions among technicians, engineers, and managers; identify and implement design and process improvements
- Communicate clearly under ambiguity, escalate technical and schedule risks early, and collaborate through disagreement
BASIC QUALIFICATIONS:
- Bachelor’s degree in mechanical, aerospace, physics, or other engineering discipline
- 3+ years of total experience in one or a combination of the following: professional experience designing, testing, and analyzing electric propulsion systems; or related spacecraft propulsion, fluid, pressure, plasma, or thruster-adjacent hardware experience (e.g., thermal, structural, power, or diagnostics for EP/plasma systems)
PREFERRED SKILLS AND EXPERIENCE:
- Demonstrated delivery of hardware for high-reliability or safety-critical use
- Working knowledge of structural design, materials properties, thermodynamics, fluid/pressure/vacuum systems, and numerical analysis programming (e.g., Python, MATLAB); plasma physics as applicable (depth in several of these areas is valued; mastery of all is not expected)
- Experience prioritizing concurrent design, build, and test work against flight and production milestones
- Clear documentation habits and attention to detail appropriate for flight hardware
- Track record of improving designs and processes for reliability, rate, or quality&
