Senior Spacecraft Thermal Engineer

Astro Digital designs, builds, and operates a diverse range of small satellite systems supporting space-based turnkey missions for several business applications, including earth observation, communications, in-orbit demonstrations, risk reduction, science, and exploration. Astro Digital is headquartered in Santa Clara, California with roughly 100 employees and infrastructure around the globe.

The Senior Spacecraft Thermal Engineer is responsible for thermal analysis and thermal-related support of all classes of Astro Digital bus.

The ideal candidate is a meticulous, self-motivated thermal engineer with deep experience in thermal analysis of spacecraft both at the system and unit level. He or she would be comfortable performing the following:

• Building both spacecraft system level and unit level models as required using Thermal Desktop
• Working with other disciplines to gather requirements and inputs necessary to complete spacecraft thermal analysis
• Presenting results in an efficient manner, identifying if requirements are met and viable solutions if not – thermal coatings, interface materials, heaters, straps, sensors, etc.
• Working with test engineers to design and execute TVAC tests

• BS in Mechanical Engineering, Aerospace Engineering, or closely related field
• 5+ years of experience as a thermal engineer or thermal analyst in the aerospace field using Thermal Desktop
• Possesses a deep understanding and intuition of thermal environments and effects
• Proficiency building Thermal Desktop models for analysis of spacecraft and subsystems
• Proficiency with performing thermal hand‑calc/back of the envelope assessments
• Experience with thermal data post‑processing (e.g., temperature data and heater power data) in Excel or Python
• Experience planning and executing thermal vacuum and thermal cycling testing
• Self‑motivated work ethic with a desire to learn new aspects of thermal analysis and engineering
• Good written, verbal, and virtual communication skills
• Willingness to travel ~5 times/yr to our San Jose, CA office and test facilities

• MS in engineering directly related to thermal analysis or thermal engineering
• Proficiency with SINDA/FLUINT and Thermal Desktop User Logic
• Experience with correlating thermal models to test data
• Familiarity interacting with version‑controlled CAD systems such as Solidworks PDM and Onshape
• Proficiency analyzing electronic components at the board level using Thermal Desktop
• Experience meshing complex geometry using TD Direct or other meshing software for use in Thermal Desktop
• Experience with modeling and implementing advanced thermal control technologies (heat pipes, PCM, TECs, etc.)
• Familiarity with standards such as NASA‑STD‑7000 (GEVS)
• Familiarity with Space
