Senior FPGA 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 The software team at K2 strives to blur the lines between the various types of software development and encourages team members to get into parts of the stack they may not otherwise have experience with. This spectrum includes HDL programming (VHDL, SystemVerilog), embedded software on microcontrollers (Rust, C++), operating systems (Rust, C++, C), application software on flight computers (Rust, C++), GNC algorithms (Rust, C++), to test systems (Python), and many things inbetween.

By doing this, we create a stronger team with more capable engineers. For now, this does not include front-end, artificial intelligence, or machine learning development. As a part of the team, you will be responsible for the development and verification of FPGA firmware used to fly some of the largest spacecraft that have ever been flown.

You will be able to write mission-critical code that controls propulsion systems, attitude control systems, RF systems, and power systems to ensure safe and reliable operation of the vehicle. In your first 6 months you will work with your team to develop core pieces of the FPGA architecture such as the strategies for fault tolerance, real-time control, high-speed data routing, and telemetry downlink. In your first year you will implement larger and more complex FPGA systems and begin verifying your code using both software and hardware in the loop simulators.

In your first two years you will operate your code on multiple spacecraft, demonstrating robust performance in demanding missions.

Responsibilities
