Senior Mechanisms Engineer

About this role

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

You will own the success of mechanisms that will be key to our satellite operation and performance. In your first 6 months, you will define mechanism requirements, trade architectures and build initial prototypes, perform preliminary and detailed analysis, define development test campaigns, trade and select any purchased components, and produce development hardware. In your first year you will validate your designs through prototype iterations in rigorous test campaigns, build, and qualify flight hardware. In your first two years you will fly your hardware in space while supporting operations, production, and integration teams as we scale.

Responsibilities

• Take hardware and mechanisms from conceptual design through qualification to on-orbit operations in order to support internal and external customer needs

• Lead design reviews from kickoff through qualification and beyond

• Drive hardware development, including hands-on development testing, analysis correlation, and follow-on hardware iterations

• Perform hardware trades that steer both sub-system and top-level product direction

• Collaborate with a cross-functional team to establish product requirements, company processes, and best practices for hardware design and manufacturing

• Continually own and refine system deliverables and associated schedules throughout development and production
