Principal Integration & Test Engineer

K2 Space•Los Angeles, CA

About The Position

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 As a Principal Integration & Test Engineer, you will help hone K2’s approach to subscale and full vehicle production, qualification testing, and operation. Your work will span most technical disciplines at the company and will require building consensus from disparate stakeholders. You will be asked to help mentors others while serving as a critical driver for on-time delivery and mitigating mission risk. Our goal is to develop a fully autonomous constellation and that starts on the ground. You’ll be the driver of constellation-level control to realize this goal.
