Senior IT Systems Engineer at K2 Space – Los Angeles | Jobyssey

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.

Step into the backbone of our organization — where your decisions keep the lights on, the data flowing, and the business moving. As our Senior IT Systems Engineer, you're not just maintaining infrastructure; you're the architect of an environment that hundreds of people depend on every single day. You'll own mission-critical systems, drive complex projects from whiteboard to production, and set the technical direction for how we scale. Every server you harden, every cloud migration you lead, and every automation script you ship makes the entire organization faster, safer, and more resilient. This is a high-trust, high-impact role for someone who thrives on solving hard problems, raising the bar for the team around them, and building infrastructure that just works — even when everything else is on fire.
