Job Description 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, however. By operating our own vehicles and manifesting regular rides to space, K2 is uniquely positioned 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. There are any number of space-based optical payloads that can generate value here on Earth (ex. forest fire detection, climate and atmospheric monitoring, etc.) and further planetary science in our solar system (ex. hyper-spectral imaging, laser-altimetry, laser propulsion). For active optical payloads, high-power amplifiers and lasers that leverage K2's on-orbit power capabilities will be a fundamental and enabling technology. Some of these near-term applications require the development of high-power, space-qualified fiber lasers and amplifiers in the near / short-wave infrared (ex. 1064nm) – but the future of atmospheric science and remote sensing will be unlocked by advances in space-qualified lasers in the UV and mid-IR. As Principal Optical Amplifier / Laser Engineer, you will define how K2 develops, designs, manufactures, tests, and deploys high-power lasers and amplifiers across all active optical payloads. The development timelines, optical power levels, operating environments, and lifetimes we are targeting require meaningful innovation; 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. Responsibilities ... of high reliability fiber amplifier systems. • Collaborate with the optical and satellite bus teams to determine optimal set of requirements for lasers and amplifiers., • As the subject matter expert on lasers and optical amplifiers at K2, conduct system engineering feasibility studies for next-generation laser technologies supporting advanced remote sensing and planetary science payloads.

Job Description 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 satellite bus is the platform – the payloads are the mission. There are any number of space-based optical payloads that can generate value here on Earth (ex. forest fire detection, climate and atmospheric monitoring, etc.) and further planetary science in our solar system (ex. hyper-spectral imaging, laser-altimetry) -- all of which require payload-specific optics benches with spectral / spatial filters, beam-shaping optics, image scanning / stabilization mechanisms, electro-optical sensors, fiber-to-free space interfaces, etc. coupled to large aperture, diffraction-limited telescopes for collecting and transmitting optical energy from the UV to the infrared. As an Optical Systems Engineer, you will contribute to defining how K2 designs, manufactures, tests, and deploys optics benches across K2's optical payload suite. You will be involved in every phase of your optical system's life cycle, from initial feasibility and architectural trade studies through manufacturing, ground testing, and on-orbit commissioning.
