Thermal Analyst

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
