Security Engineer, Operations

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 be on the front lines of protecting the systems, data, and teams that make high-powered satellites a reality. You’ll dive into real-world security operations – monitoring alerts, investigating incidents, and hunting for threats to ensure our corporate and mission-critical environments stay resilient and secure.

Every alert you investigate, every vulnerability you remediate, and every improvement you implement directly enables Engineers and Operators to move fast, innovate, and push the boundaries of space technology. This is hands-on, high-impact work where your expertise safeguards the foundation of our missions and keeps K2 Space moving boldly forward.
