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 Solar power isn’t a subsystem at K2, it’s the capability that makes everything else possible. Our arrays are what allow us to operate at power levels no satellite has ever sustained, across the most demanding orbits in the solar system.

Getting that right, at scale, is one of the most consequential engineering challenges in the company. As Head of Solar, you’ll own it entirely. From early-stage technology development and module innovation through design maturation, manufacturing, test, and on-orbit performance – the solar array program is yours to build and lead.

You will grow a cross-functional organization spanning design, analysis, manufacturing, and integration, and set the technical direction and operational cadence needed to meet our most ambitious cost, schedule, and reliability targets. The missions we’re building toward are unlike anything the industry has flown: extreme radiation environments, multi-year lifetimes, and production volumes that demand manufacturing infrastructure built for rate and not one-off heroics. This is a rare opportunity to define what world-class solar engineering looks like inside a vertically integrated space company, and to build the team and systems that make it real.

Responsibilities

Build, scale, and lead the Solar Engineering organiz ation across design, manufacturing, process, and automation disciplines Own the solar hardware technical baseline end-to-end: from array and module design through p rocess qualification, tooling and automation infrastructure, and flight-ready production delivery Take hardware and mechanisms from conceptual design through qualification to on-orbit operations, including hands-on testing, analysis, and iterative design refinement Identify and invest in transformative technologies that unlock step-change improvements in rate, reliability, and unit economics Set the strate gic direction for how solar hardware is designed and manufactured at scale, establishing the systems, processes, and standards that enable high-rate production Collaborate with a cross-functional team to establish product
