Job summary

K2 Space is building the largest and highest-power satellites to push performance limits across orbital regimes. You will join the Thermal team to build and run models predicting temperatures through ground processing, launch, and on-orbit operations.

This role emphasizes analysis and simulation, not hardware sizing, with your outputs guiding the engineers who size hardware. You will collaborate with design engineers early to ensure manufacturability, help design the build flow, and finalize the

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.

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
