Apex manufactures satellite buses (commercial spacecraft platforms) at scale, combining software, vertical integration, and hardware designed for manufacturing. The company enables earth observation, communications, and other critical space applications.
You will own the thermal design and performance of spacecraft from concept through flight operations. This is a hands-on role solving complex thermal challenges across the vehicle, developing and validating spacecraft-level thermal models, and directly influencing hardware design and mission performance.
Key Responsibilities:
- Develop and maintain spacecraft-level thermal models using Ansys Thermal Desktop
- Perform thermal analyses to evaluate spacecraft performance across mission environments
- Develop thermal control solutions and drive thermal design decisions across spacecraft systems
- Plan and execute thermal subsystem milestone reviews (SRR, PDR, CDR)
- Support thermal flight hardware integration, build, and test
- Design, plan, and execute thermal vacuum testing at component and spacecraft levels
- Correlate test and flight data to thermal models to improve accuracy and performance predictions
- Collaborate with mechanical, systems, avionics, and other engineering teams to meet thermal requirements
Requirements:
- U.S. Person status required (access to export-controlled data)
- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field
- 5+ years of experience in thermal engineering or analysis
- Experience with thermal modeling and analysis tools
- Strong understanding of heat transfer and thermal engineering fundamentals
- Strong analytical and problem-solving skills; ability to work in fast-paced environment
Preferred Qualifications:
- Experience with spacecraft or aerospace thermal systems
- Proficiency with Ansys Thermal Desktop
- Experience designing spacecraft thermal control systems
- Experience with thermal vacuum testing, instrumentation, and data acquisition
- Experience correlating thermal models with test or flight data
- Familiarity with spacecraft thermal margin standards and requirements
- Working knowledge of two-phase thermal control systems
- Experience with Siemens NX and Teamcenter
