Thermal Engineer Redmond, WA

Starcloud is building a network of data centers in space, starting at kilowatts and scaling to gigawatt capacity. Falling launch costs allow us to take advantage of the abundant energy, radiative cooling techniques, and ability to rapidly scale in space. Join our team, push the boundaries of the space economy, and be part of this pioneering effort to redefine the future of energy.

As a Thermal Engineer at Starcloud, you will be instrumental in designing and developing thermal control systems for our space-based data centers. This hands‑on role requires a highly innovative and dynamic individual with extensive experience in thermal analysis and design. You will conduct detailed thermal analyses, design optimizations, and lead testing and validation efforts to ensure system reliability and performance.

• Design and Analysis:
  • Conduct preliminary and detailed thermal analysis on spacecraft and subsystems for operational conditions in orbit. These subsystems include cold plates, coolant loops, pumps, and very large lightweight deployable radiators, working closely with the mechanical and mechanisms teams.
  • Design, analyze, and optimize these thermal control systems, balancing performance, mass, cost, and reliability.
  • Provide thermal analysis and recommendations during architectural trades, supporting system architects and subsystem leads.
• Testing and Validation:
  • Conduct rapid prototyping and testing of engineering models for iterative design feedback.
  • Take responsibility for building FM thermal hardware.
  • Define, lead, and execute thermal cycling and thermal vacuum tests for development and qualification at subsystem and spacecraft levels.

• Bachelor’s degree in Mechanical Engineering or a related discipline, or equivalent experience.
• Good competency with Thermal Desktop and Ansys.
• 5+ years of experience with active thermal control, ideally in the space domain, delivering solutions optimized for mass, cost, reliability, performance, and manufacturability.

• Proven track record in spacecraft thermal design, delivering optimized solutions for mass, cost, reliability, performance, and manufacturability.
• Experience developing hardware and spacecraft that have successfully operated in space.
• Experience interpreting and correlating data from on‑orbit telemetry.
