Full 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 $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 You will play a defining role in how K2 Space secures and scales its corporate operations. You’ll architect the security foundations that protect our people, systems, and data while enabling the rapid development and operation of high-powered satellites. This role is about building security into the fabric of the company – across identity, endpoints, networks, and cloud platforms—so teams can move quickly and confidently. As K2 Space grows from early missions to sustained operations, your work will directly enable scale without friction. The security architecture and standards you establish will shape how the company operates and protects its most ambitious work for years to come. Responsibilities
