Senior Build Reliability 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

As a Senior Build Reliability Engineer, you’ll be the person who ensures that every satellite we ship is built to fly. You will own quality and reliability from the moment raw materials hit our dock to the moment a finished vehicle leaves for the launch site. You’ll dig into failures, find the root cause, and make sure it never happens again. You’ll write the quality plans and build the processes that let us scale from building a few spacecraft to building many, without compromising the reliability that missions demand.

Being hands-on will be part of your routine as you’ll work alongside engineers and technicians, shaping how hardware gets built. You’ll influence design decisions with data from the production floor. You’ll help establish the manufacturing practices that will underpin Commercial, National Security, and Science missions spanning LEO, MEO, GEO, Cislunar, and Deep Space.

If you want to build the quality culture in a fast paced environment and enable high-rate satellite manufacturing at scale, this is the role.

Responsibilities

• Own and execute quality plans across assigned build programs, from receiving inspection through integration, test, and vehicle handoff at the launch site
