Thermal Analyst

The Role

You will support the Thermal team by building and running thermal models that predict spacecraft and component temperatures across all mission phases including ground processing, launch, and on-orbit operations. Working closely with Thermal Design Engineers, you will translate CAD geometry and mission timelines into orbital thermal models, run steady-state and transient simulations, and help correlate model predictions against test data. This is an analysis and simulation-focused role: you won't be sizing hardware or running TVAC campaigns yourself, but your models will directly inform the engineers who do.

You will partner with design engineers early in the process to ensure manufacturability while building the first prototype, design the build flow, and finalize the process for transition to production.

Responsibilities

• Work with lead engineers to design active and passive thermal control systems using basic heat transfer and mechanical equations to size lines, pumps, accumulators, cold plates etc.
• Planning and development of thermal cycle and thermal-vacuum testing campaigns
• Design and development of heater and cooling systems including control architecture
• Setup, commission, and maintain state-of-the-art test stands and instrumentation
• Develop data acquisition systems for active and passive thermal control systems
• Perform tests on novel pump fluid loop including feed systems, power electronics, and hardware-in-the-loop
• Develop testing and control scripts to conduct safe and reliable test campaigns of pump fluid loop and individual components
• Create formal documentation for development and production: test procedures, test reports, and standard operating procedures
• Troubleshoot electrical and mechanical test setups and hardware
• Document, compile, analyze, and present test data

Qualifications

• 3+ years of experience with thermal test experience in a high-rate manufacturing environment
• 2+ years of experience with sizing and testing fluid systems including pumps, valves, accumulators, heat exchanger, cold plates etc.
• Demonstrated experience with data acquisition for thermal and power related applications
• Experience with test plan development and execution
• Strong experience with thermal and TVAC testing including setup, instrumentation, and troubleshooting
• Demonstrated knowledge of NX or AutoCAD is preferred to design test fixtures

Nice to Have

• Experience with Thermal Desktop and basic statistical data analysis
• Experience with signal conditioning to define optimal acquisition rate and understand when signal-to-noise ratio is not acceptable
• Experience with pumps testing
• Experience with avionics testing
• Experience with testing refrigeration systems

Compensation and Benefits:

• Base salary range for this role is $100,000 - $220,000 + equity in the company
• Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
• Comprehensive benefits package including paid time off, medical/dental/vision/ coverage, life insurance, paid parental leave, and many other perks
