Senior Electrical Engineer, High Speed Mixed Signal

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.

You will be responsible for leading the design and development of high‑speed mixed‑signal electronics to be hosted on some of the largest, most powerful, rapidly designed and rapidly manufactured satellites ever deployed in space. In your first 6 months, you will architect, develop, test, and integrate new high‑speed electronics for use in SDR (software‑defined radio) systems for satellite communications and beyond.

You will work with a multidisciplinary team of RF (radio frequency), FPGA (field‑programmable gate array), software, mechanical, and electrical engineers in order to prototype your systems and refine your designs. In your first two years, you will have flown your system in space and developed cutting‑edge high‑speed mixed‑signal electronics systems.
