Battery Test Engineer, Satellites (Starlink)
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.
BATTERY TEST ENGINEER, SATELLITES (STARLINK)
SpaceX is leveraging its experience in building rockets and spacecraft to deploy Starlink, the world’s most advanced broadband internet system. Starlink is the world’s largest satellite constellation and is providing fast, reliable internet to millions of users worldwide. We design, build, test, and operate all parts of the system – thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that brings it all together. We’ve only begun to scratch the surface of Starlink’s potential global impact. As we continue to upgrade and expand the constellation, we’re looking for best-in-class engineers to join the team.
Starlink Development Battery Test is a fast-paced R&D focused group that aims to increase reliability by testing Starlink’s next-generation batteries. As a Battery Test Engineer you will design, fabricate, and implement battery test equipment as well as conduct development tests for the new battery packs and cells.
This role will help build out a comprehensive test suite to ensure the reliability, safety, and performance of the Starlink battery systems ranging in size from single cells to full packs. This individual is ultimately responsible for the outcome of Starlink batteries and must define overall test campaigns necessary to assess the performance of new cell technologies across our operational conditions and determine whether the fully assembled pack will function reliably, and safely, in-orbit for the life of the satellite. This role encompasses design, analysis, and manufacturing disciplines, with the ability to spearhead large-scope projects from early design trades through implementation. This individual should be passionate about batteries with a background in mechanical engineering.
RESPONSIBILITIES:
- Create test fixturing concepts, fabrication drawings, wiring schematics, and to establish mechanical, thermal, and electrical tests necessary for rapid development of battery packs and cells
- Develop and maintain test facilities including abuse testing chambers and vacuum chambers
- Establish safety protocols for high voltage applications and various destructive tests of battery cells
- Design test fixtures and data acquisition systems
- Document test plans, procedures, and results
- Provide feedback on system level design trades
- Design and analyze structures, fluid systems, and mechanisms
- Operate test beds with great attention to detail (tests have very little margin for error, so attention to detail is a crucial and essential characteristic of a development test engineer)
- Develop test requirements with the flight engineering team, develop a design solution that meets or exceeds those requirements, and drive the campaign to closure
BASIC QUALIFICATIONS:
- Bachelor's degree in mechanical engineering
- 1+ years of experience in one or more of the following:
- Involvement with an extracurricular project team designing and building mechanical fixturing and/or battery systems
- Academic research on mechanical structures and batteries
- Professional experience designing and analyzing mechanical structures and fixturing
PREFERRED SKILLS AND EXPERIENCE:
- Experience with electrical, electrochemical, fluidic, electromechanical, thermal, structural, pneumatic, and vacuum systems
- Experience with basic test instrumentation such as current sensors, contactors, pressure transducers, thermocouples, RTDs, strain gauges, accelerometers, flow meters, load cells, relays, solenoid valves, and encoders
- Experience with Arbin and Novonix cell cyclers
- Experience with Unigraphics (NX) or similar CAD programs
- Experience performing finite element analysis (FEA)
- Experience with lithium-ion battery handling, safety and usage
- Demonstrated understanding of structural and mechanical first principles analysis
- Familiarity with battery cell first principles
- Demonstrated full-cycle ownership of a hardware project from concept to implementation
- Hands-on experience with testing, data acquisition, and troubleshooting issues
- Hands-on design and fabrication experience
- Basic programming skills (Python and SQL preferred)
ADDITIONAL REQUIREMENTS:
- Must be willing to travel as needed, up to 25% to other SpaceX sites
- Physical effort including standing, lifting, and carrying equipment up to 25 lbs. unassisted
- Ability to work in outdoor environments as needed
- Must be available to work extended hours and some weekends
COMPENSATION AND BENEFITS:
Pay range:
Battery Test Engineer/Level I: $100,000.00 - $115,000.00/per year
Battery Test Engineer/Level II: $110,000.00 - $135,000.00/per year
