Job description

MECHANICAL ENGINEER - BATTERY PACK, SATELLITES (STARLINK)

SpaceX is looking for a Mechanical Engineer to join the Starlink Battery team, focusing on battery pack-level design and development for our next generation of satellites. You will be responsible for cell-to-pack design, maximizing energy density and manufacturability of the packs while ensuring reliable long-term operation in Low Earth Orbit.

RESPONSIBILITIES:

  • Design satellite battery packs that integrate thousands of 2170-format cylindrical cells at high voltage
  • Perform CAD & analysis of the mechanical, electrical, and thermal performance of packs under conditions spanning ground-side validation through on-orbit operation
  • Drive design trades that maximize pack-level Wh/kg and minimize $/kWh, while ensuring manufacturability and fault tolerance across satellite life
  • Conduct DFMEAs and root-cause analyses to anticipate issues and ensure long-term reliability
  • Validate designs via qualification testing including vibration, thermal, environmental, & vacuum testing
  • Work closely with manufacturing teams to develop efficient in-house production process for pack assembly; own the pack lifecycle from upstream component vendors through pack production
  • Demonstrate extreme ownership of product outcomes at every stage of development and production; own product delivery timeline through conception, design, assembly, and launch
  • Collaborate with supporting teams including battery cell, production & manufacturing, abuse testing, flight software, and thermal analysis to ensure high-reliability pack performance & operation

BASIC QUALIFICATIONS: 

  • Bachelor's degree in an engineering or other STEM discipline
  • Experience with CAD and FEA software packages 
  • 1+ years of experience with battery pack design, analysis, testing, and/or manufacturing (internships, co-ops, lab work and club-team experience can apply)

PREFERRED SKILLS AND EXPERIENCE: 

  • 2+ years of professional experience in mechanical design and analysis
  • 2+ years of hands-on project experience with complex mechanical systems, preferably as a team lead
  • Professional experience with 2170-format battery design, manufacturing, and testing
  • Proficiency in CAD and analysis software (NX, ANSYS, and FEMAP preferred)
  • Solid understanding and application of GD&T
  • Experience executing designs from prototypes through high-volume production ramp
  • Self-motivated with strong organizational, written, and oral communication skills 
  • Experience with design of experiments, statistical process control, and process qualification
  • Experience working with PCB designers and exposure to PCB layout and PCBA mechanical design

ADDITIONAL REQUIREMENTS: 

  • Must be willing to work extended hours and weekends as necessary for mission critical deadlines
  • Must be willing to travel as needed
COMPENSATION AND BENEFITS:
Pay Range:
Level 1: $100,000.00 - $135,000.00
