Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Battery Test Engineer - **Company:** Space Exploration Technologies Corp. - **Location:** Redmond, WA, United States - **Salary:** $100,000.0 - $115,000.0 - **Contract:** Permanent contract - **Skills:** Computer-Aided Design, Test Suite, Python (Programming Language), SQL Databases, Siemens NX - **Published:** September 3, 2026 - **Apply:** https://www.themuse.com/jobs/spacex/battery-test-engineer-satellites-starlink ## About the Role 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., * 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, * To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
