Job summary

K2 Space Corporation in Torrance, California is seeking a Thermal Control System (TCS) Design Engineer to own the development, implementation and testing of both R&D and production thermal control systems for our satellites. You will lead design and verification efforts for active and passive thermal control components and interfacing ground support equipment.

Collaborate with design engineers early to ensure manufacturability, build the first prototype, and define the build flow for production

Qualifications

• 3+ years of experience with thermal test in a high-rate manufacturing environment.
• 2+ years sizing and testing fluid systems including pumps, valves, accumulators, heat exchangers, cold plates.
• Demonstrated experience with data acquisition for thermal and power 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

• 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 develop ment 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

Job description

Thermal Control System (TCS) Design Engineer

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by $450M from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others – with an additional $500M in signed contracts across commercial and US government customers – we’re mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.

The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today’s and tomorrow’s massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.

With multiple launches planned through 2026 and 2027, we're Building Bigger to develop the solar system and become a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a groundbreaking Series C space startup, we’d love for you to apply.
