Description

  • Develop, maintain, and mature integrated spacecraft thermal models at the vehicle, subsystem, and component levels.
  • Define thermal architectures and requirements, and iterate hardware designs with cross-disciplinary engineering teams.
  • Generate flight temperature predictions, margins, and off-nominal analyses, and communicate guidance to the broader engineering team.
  • Ensure spacecraft payloads stay within operating and survival limits across all mission phases using passive and active thermal control strategies.
  • Correlate thermal models to component-, subsystem-, and vehicle-level test and flight data.
  • Serve as the thermal technical authority across the spacecraft lifecycle, from early trade studies through mission operations.
  • Translate mission environments and operational concepts into hardware requirements.
  • Support test correlation, flight qualification, and mission operations decisions.

Requirements

  • Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or a closely related field.
  • 6+ years of experience developing and applying thermal models for spacecraft or flight hardware.
  • Proficiency with spacecraft thermal analysis tools such as Thermal Desktop, ANSYS, or similar software.
  • Experience anchoring thermal models to test and/or flight data and using results to drive design decisions.
  • Strong understanding of lumped-parameter (0D/1D) thermal networks and appropriate use of higher-fidelity methods.
  • Effective technical communicator with demonstrated success working cross-functionally in fast-paced environments.
  • Familiarity with spaceflight thermal margin, qualification, and verification standards, such as SMC-S-016, is preferred.
  • Experience planning or executing spacecraft environmental testing, including TVAC, is preferred.
  • Experience across a full spacecraft lifecycle, from concept development through on-orbit operations, is preferred.
  • Prior experience supporting flight thermal predictions or mission operations is preferred.

Benefits

  • Competitive salary with equity.
  • Hiring range of $164,000 to $225,500 USD.
  • Generous PTO and sick leave policy.
  • Parental leave.
  • Annual learning and development stipend.
  • Total rewards package with additional benefits and perks.
  • Compensation determined based on experience, qualifications, and other job-related factors.
