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.   The Role   You will own the success of developing, implementing and testing both R&D and production thermal control systems on the spacecraft. You will be responsible for spearheading the design and verification efforts of active and passive thermal control systems including, but not limited to, pump fluid loops, heat pipes and all of the required ground supporting equipment (test fixtures, diagnostic equipment, instrumentation, software tools etc.). Y our work will require familiarity with pressurized systems (valves, pumps, accumulators, heat exchangers), thermo-mechanical instrumentation (temperature sensors, pressure sensors, flow meters etc.), integrated electronics systems, and secondary satellite structures.   You will partner with design engineers early on 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 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  l oop 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
