Avionics & Radiation Effects Test Technician

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 critical role in the qualification, implementation and reliability of our satellite’s avionics hardware in the most intense radiation environments of space. You will own the rapid development of component, board and subsystem level radiation test setups that you will execute at national labs across the country, while growing the team’s capabilities through test rack and automation development to keep up with our growing business needs. Through detailed analysis and reporting of your test results, you will inform hardware designers and mission planners of how to confidently operate our satellites to meet our Commercial, National Security and science customer’s needs. As an essential part of the engineering team, you will demonstrate excellent test engineering fundamentals and a high level of attention to detail to ensure our hardware and test capabilities are second to none. Prior experience in radiation effects testing is preferred but not required; strong electrical lab skills and a willingness to learn are essential.
