About the role

  • We are seeking a highly-motivated and hands-on Senior Spacecraft Thermal Engineer to join our growing team.
  • You'll work with a multidisciplinary team of optical, electrical, mechanical, and software engineers to ensure thermal stability and performance for ground-based and potential future space-based deployment.

Responsibilities

  • Design and optimize thermal control systems for spacecraft and telescope platforms (e.g., radiators, heaters, insulation, thermal straps, and enclosures).
  • Develop thermal models and perform detailed thermal analysis (steady-state and transient) across operational environments.
  • Perform STOP analysis (Structural, Thermal, Optical Performance) to verify system-level thermal stability and its impact on optical performance.
  • Collaborate with optics, mechanical, and electrical teams to ensure proper thermal integration with imaging, tracking, and sensing subsystems.
  • Support environmental testing, including thermal vacuum (TVAC), thermal cycling, and validation of thermal models.
  • Support the full product lifecycle, from concept design and prototyping to testing and production.
  • Participate in and contribute to design reviews (PDR, CDR, etc.) and internal documentation.
  • Provide engineering support during fabrication, integration, QC, and system validation.
  • In this role, you'll design and develop thermal control systems for telescope platforms and spacecraft.
  • We require a minimum of 3 days per week in our office to support collaboration and team culture. (LA Office only)

Requirements

  • Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or equivalent.
  • 5+ years of experience in thermal engineering for aerospace or high-performance systems.
  • Strong understanding of heat transfer fundamentals (conduction, convection, radiation).
  • Experience with thermal analysis tools (e.g., Thermal Desktop, SINDA/FLUINT, ANSYS, or similar).

Nice to have

  • Experience with spacecraft thermal control systems and space environments (LEO, GEO, or deep space).
  • Understanding of FEA (ANSYS, Nastran, etc.), tolerance analysis, and DFM principles.
  • Experience with thermal vacuum (TVAC) testing, thermal cycling, and model correlation.
  • Experience working in fast-paced, early-stage or startup environments.
  • Basic scripting or automation (Python, MATLAB) for thermal modeling or data analysis.
  • We encourage everyone to rest, recharge, and take care of themselves.
  • Cutting-Edge Tools - Get access to the latest hardware and software you need to do your best work.
  • Inclusive Team - We foster a supportive and diverse workplace where all voices are valued.
