Senior Harness Design Engineer

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price — and with over $1 billion 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 in 2027 and plans to scale to 100 satellites a year, we're Building Bigger — helping develop the solar system and build toward 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 high-growth Series D-funded company, we'd love for you to apply.

You willbe responsible for harness and wiring system design, analysis,testing and integration on some of the largest, most powerful, rapidlydesignedand manufactured satellites. You will have the unique opportunity tocollaboratewith a cross functional team of engineers and own tradesto reduce cost,increaseintegrationrate,anddecreasemassof bus and payload harnessing.

You will be the Responsible Engineer forharnesssystem design and components such as connectors, wire and cable,instrumentation,and heaters. You will helpestablishproduction testrequirementsand supportvehicleavionics integration to enable high-rate production and constellation launch cadence. In your first two years, you will have qualified hardware for flight, completed avionics integration on the satellite bus, and flown your hardware through intense LEO, MEO and GEO environments.
