Radiation Effects Engineer

<div class="content-intro">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.</div>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. 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.  Responsibilities  <ul> <li>Execute cradle-to-grave radiation test campaigns (SEE, TID, DDD and materials) through coordinating test facilities/dates, designing electrical test setups, writing test procedures, executing tests, and documenting results </li> <li>Design, fabricate, and assemble production quality test racks, test PCBAs, and cable harnesses </li> <li>Troubleshoot, repair, and modify electronic components, assemblies, parts, and systems </li> <li>Perform tests and checkouts using standard lab equipment such as programmable power supplies, ohmmeters, oscilloscopes, DMM, SMU, logic analyzers and DAQs.  </li> <li>Develop basic test automation, data collection and analysis scripts in Python </li> <li>Own the scheduling and prioritization of component, board and subsystem radiation testing to support the hardware and vehicle lifecycle </li> <li>Flash firmware and perform software load verifications under the direction of engineering team members </li> </ul> Qualifications  <ul> <li>Bachelor’s degree in e
