Satellite Thermal Engineer III

Join to apply for the Satellite Thermal Engineer III role at Blue Origin

Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low‑cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! The role is part of the In‑Space Systems business unit, which is focused on addressing two of the most compelling challenges in spaceflight today: space infrastructure and increasing mobility on‑orbit.

As part of a hardworking team of engineers you will be responsible for the thermal design, analysis, and testing of satellite systems within our In‑Space Systems business unit. You will work within an integrated engineering team to develop innovative thermal control solutions for our spacecraft, ensuring optimal performance in the extreme conditions of space. Your expertise in thermal management will be crucial in supporting Blue Origin’s mission of enabling millions of people living and working in space to benefit Earth.

• Design and implement thermal control systems for spacecraft and satellites, including radiators, multi‑layer insulation (MLI), thermal coatings, heaters, and heat pipes
• Develop detailed thermal models and perform simulations using industry‑standard software such as Thermal Desktop and SINDA/FLUINT
• Identify and manage worst‑case scenarios in extreme thermal conditions (both hot and cold), accounting for orbital environmental factors and internal power losses
• Analyze and optimize heat transfer mechanisms within spacecraft systems
• Define thermal interfaces and ensure proper integration with other satellite subsystems
• Lead thermal qualification testing and validation activities for flight hardware
• Present technical information at design reviews and provide thermal analysis reports

• B.S. degree in Aerospace, Mechanical Engineering, or related engineering field
• 5+ years of experience in spacecraft thermal engineering with demonstrated expertise in thermal analysis and design
• Proficiency with thermal modeling and analysis tools, particularly Thermal Desktop
• Experience designing and analyzing radiators, multi‑layer insulation, and thermal control coatings for spacecraft applications
• Strong understanding of heat transfer principles and mechanisms in space environments
• Experience with thermal vacuum testing and correlation of thermal models to test data
• Ability to communicate complex technical concepts clearly to a variety of audiences
• Demonstrated ability to lead technical efforts and drive solutions within an integrated engineering team

• M.S. or Ph.D. in a relevant engineering discipline
• Knowledge of spacecraft power systems and their interaction with thermal management
• Experience with advanced thermal control technologies such as heat pipes, loop heat pipes, or mechanically pumped fluid loops
• Familiarity with the qualification process for spacecraft thermal systems
• Experience with technology development or maturation efforts, including leading development testing
