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 K2’s plan doesn't stop at satellite buses. Operating our own vehicles and manifesting regular rides to space uniquely positions K2 to design, test, and deploy-at-scale ambitious optical payloads in MEO, GEO, cis-lunar, and deep space on unprecedented timelines. The satellite bus is the platform – the payloads are the mission. As a Principal Optical Test & Automation Engineer, you will be responsible for the strategic roll out, design, commissioning (build, alignment, and bring-up), and maintenance of all optical test and automation infrastructure. In this role, you will have one of the best system engineering vantage points with which to understand how each optical payload works, identify when flight hardware isn’t behaving as intended, and suggest when hardware complexity can be offloaded to software and test. You will own the design and development of: flight-like hardware-in-the-loop infrastructure for developing software and algorithms; automation of sub-system and end-of-line testing and calibration; and robotic active alignment ( for only the highest volume payloads) ...all of which are themselves sophisticated optical assemblies. The sophistication and variety of optical test infrastructure we are targeting will require meaningful innovation, but you will have the resources and full support of K2 to make this possible and help raise the bar for the next generation of space technology companies. K2 believes that this is how you build optical systems at scale, and that this is the future of space exploration.
