Senior FPGA Prototyping Engineer

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 We are seeking a Senior FPGA & Silicon Bring-up Engineer to accelerate the development of next-generation communications ASICs.

You will own FPGA prototyping, firmware enablement, first-silicon bring-up, and hardware validation, serving as the bridge between ASIC design, firmware, software, and system integration.

This role spans the entire silicon lifecycle from pre-silicon FPGA platforms that enable early hardware/software integration to post-silicon debug, interface validation, and automated test infrastructure.

Responsibilities

Develop FPGA-based prototypes to enable early ASIC integration, firmware development, and system validation. Build hardware platforms that allow software and firmware te
