Principal Solar Design Engineer

About K2 Space

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, and Alpine Space Ventures, we are mass-producing the highest-power satellite platforms ever built for missions ranging from Low Earth Orbit (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. 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 are "Building Bigger" to develop the solar system and become a Kardashev Type II (K2) civilization. We are a groundbreaking Series C space startup looking for motivated individuals who thrive in a fast-paced environment and are excited about contributing to our success.

About the Role

Critical to achieving K2's vision of deploying at scale across MEO, GEO, cis-lunar, and deep space are the solar arrays. Scaling to constellations requires someone who can span technical domains from module technology and electrical power system interactions to soft goods, deployment mechanisms, structures, integration, and high-rate production.

You will define how K2 develops, designs, manufactures, tests, and deploys high-power solar arrays at production scale. The development timelines, operating environments, mission lifetimes, and cost targets we are pursuing demand meaningful innovation. You will have the resources and full support of K2 to make this possible and help raise the bar for the next generation of space technology companies.

Application & Culture

If you don't meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other, and non-traditional career twists and turns are encouraged.

If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.
