## Job description

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price — and with over $1 billion 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 in 2027 and plans to scale to 100 satellites a year, we're Building Bigger — helping develop the solar system and build toward 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 high-growth Series D-funded company, we'd love for you to apply.

You will be responsible for architecting and evolving the core operating system capabilities of some of the largest spacecraft ever flown, ensuring a reliable boundary between SoC specific complexity and high-level flight software. You will write mission-critical code that maintains a secure boot chain and platform for safe operation of the vehicle. In your first 6 months you will develop core pieces of the software platform including tuning Linux to meet hard real-time requirements, and creating a shared sense of time across the vehicle. In your first year you will develop a strategy and tooling to ensure we can utilize the latest Kernel versions with confidence. In your first two years you will operate your code on multiple spacecraft, demonstrating robust performance in demanding missions.
