<div class="content-intro"><p data-renderer-start-pos="41">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.</p> <p data-renderer-start-pos="570">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.</p> <p data-renderer-start-pos="994">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.</p></div><p><strong><span data-contrast="auto">The Role:</span></strong><span data-contrast="auto"> </span><span data-ccp-props="{}"> </span></p> <p><span data-contrast="auto">We are seeking an experienced Cybersecurity Architect to support classified programs in direct service to the Department of Defense (DoD) and Intelligence Community (IC).
