Senior Electro-Mechanical Test Engineer

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. The Role You will own the success of piece part, component, and subsystem testing across electromechanical systems. You will lead projects and help stand-up infrastructure to support the core testing and production infrastructure. In your first 6 months, you will define production test campaigns, design and build test setups, and be hands-on with flight hardware. In your first year, you will validate designs through prototype testing and lead large multidisciplinary test campaigns, along with ramping production throughput. You will drive best practices by leading large test campaigns and mentoring the growing team. This role will include ownership all of the way from low-rate research and development through high-rate production lines. Responsibilities Own kickoff, design, fabrication, build, activation, data collection, and conclusion/results for both development tests and production testing at rate Design test hardware, fixturing, and tooling using CAD, schematic tools, electrical analysis, and hand calculations Demonstrate best practices for activating test assets, operating test equipment, instrumentation, and executing tests in a safe and organized manner Troubleshoot performance issues and recommend solutions during test campaigns and production buildout Clearly communicate technical data, findings, and recommendations to team members across all levels of the organization Lead improvements to testing standards with company-wide impact by creating tools, methods, and processes Guide and mentor team members with designs, workload, scheduling, and communication Q ualifications Bachelor’s…
