About the role

Key responsibilities & impact
  • Deliver and take full ownership of the satellite thermal control system from scratch
  • Work with mechanical, propulsion, electronics, and mission-planning teams
  • Ensure reliable satellite thermal performance across launch, in-orbit operation, and end-of-life
  • Perform steady-state and transient thermal analysis across TVAC testing, launch, and orbit
  • Model and validate heat-management strategies in vacuum, where conduction and radiation dominate
  • Identify and manage worst-case hot and cold thermal scenarios, including on-orbit environmental factors and internal power dissipation
  • Design and implement thermal control solutions including MLI, radiators, heaters, thermo-optical coatings, thermistors, and thermal straps
  • Develop and support TVAC test procedures, instrumentation setup, and post-test data analysis
  • Conduct hands-on hardware testing to validate processes, instrumentation, materials, and components for in-house developments

Requirements

What you’ll need
  • Experience in spacecraft thermal management at both subsystem and spacecraft level
  • Solid understanding of thermal engineering principles in the context of spacecraft systems
  • Hands-on experience with thermal simulation tools such as Systema, Thermal Desktop, ESATAN, or equivalent
  • Experience with environmental and lab testing, including TVAC, thermal cycling, and AIT process validation
  • Comfortable working in a fast-paced, iterative development environment
  • Experience designing or testing spacecraft thermal systems is nice to have
  • Exposure to multidisciplinary space system development or mission analysis is nice to have
