Job summary

Blue Origin is seeking a Senior Satellite Thermal Engineer to own the thermal performance of one or more TeraWave LRUs, from requirements through production release. You will develop detailed models, drive trades, and support vacuum testing in a fast-moving team, ensuring thermal integrity for space environments and production rates.

You will define interfaces with systems and mechanical teams, correlate models to hardware data, and lead thermal control procedures across all mission phases while

Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a closely related field.
• 8 or more years of hands-on experience in spacecraft component or LRU thermal engineering or thermal control systems development.
• Proficiency with thermal modeling software- Thermal Desktop, SINDA/FLUINT, Ansys Icepak, or comparable tool, with model-to-test correlation.
• Demonstrated experience with spaceborne thermal design including vacuum environments, radiation heat transfer, and flight hardware qualification.
• Hands-on experience with spacecraft thermal testing including thermal vacuum test setup, data review, and model-to-test correlation.
• Must be a U.S. citizen or national, U.S. permanent resident (Green Card), or lawfully admitted into the U.S. as a refugee or granted asylum.

Responsibilities

• Own the thermal performance of assigned LRUs from requirements through qualification and production release.
• Define LRU thermal requirements and interfaces in coordination with systems and satellite teams.
• Develop detailed thermal models using Thermal Desktop, SINDA/FLUINT, or equivalent.
• Perform transient and steady-state analyses for mission profiles and environmental conditions.
• Drive thermal design trades balancing performance, mass, power, producibility, and cost.
• Collaborate with mechanical, electrical, and packaging engineers to integrate thermal constraints.
• Develop thermal loads from first principles, literature, and test data; document inputs and results.
• Support hardware development through vacuum testing, model-to-test correlation, and anomaly resolution.
• Assess third-party models and develop simplified models for integration.
• Develop thermal control procedures for all mission phases.
