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’ll help safeguard the technology and teams building a new class of high-powered satellites. You’ll be deeply hands-on – deploying, operating, and refining security controls across identity, endpoints, networks, and cloud platforms that support fast-moving engineering and mission operations. This is a role for someone who thrives on real-world impact: turning security strategy into practical, resilient protections that scale as K2 Space grows. Every system you harden and every risk you reduce directly supports our ability to move fast, operate confidently, and deliver breakthrough satellite capabilities.
