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. 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.

Responsibilities

• Design and fabricate test hardware, harnessing, and test systems to support optical payload development testing
• Develop modular, reusable test automation software and drivers in Python, Rust, C++ for Linux platforms
• Execute development and production tests to meet internal and external customer needs
• Develop data acquisition, control, and instrumentation systems to test at the integrated level
• Own the project management of multiple test assets and acceptance testing of optical avionics including upgrades to support hardware lifecycle
• Design device simulators deployed across component subsystem and HITL testbeds
• Collaborate with a cross-functional team to establish product requirements, testing methods, and project test schedules
• Design and build optical tables with automated active alignment for high-rate optical testing

Qualifications

• Bachelor’s degree in electrical, computer, aerospace, or other relevant engineering discipline or any equivalent combination of education and experience
• 5+ years of experience with test hardware design and software scripting
• Strong programming abilities (Python, C++, or Rust)
• Experience designing, building, and testing electrical assemblies and test fixtures

Nice to Have

• Experience with design and testing of optical systems
• Experience with camera automation and quantitative image processing (ex. beam profiling), power meters, and laser interlocks.
• Experience with data acquisition, controls, and dedicated test equipment
• Familiarity with SMC-S-016 or MIL-STD-810 testing methods, including vibration, shock, and thermal testing
• Understanding of the failure modes of electrical and optical systems in space environments
• Demonstrated ability to own electrical or optical hardware test systems within an integrated engineering team
• Creative problem solver that can balance schedule, resource, and technical constraints

Compensation And Benefits

• Base salary range for this role is $150,000 - $200,000 + equity in the company
• Salary will be based on several factors including, but not limited to knowledge and skills, education, and experience level
• Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks

If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!

If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.
