Spacecraft Propulsion Technician

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. The Role As a Spacecraft Propulsion Technician, you will be part of the team developing and scaling production of the highest-powered electric propulsion system ever put into orbit. In this role you will support Hall effect thruster assembly, COPV proof testing, and system level production acceptance testing. The ideal candidate is a highly hands-on technician comfortable working across mechanical, electrical, and fluid systems in a fast-paced environment. Responsibilities Perform hands-on assembly of the Hall thruster and sub-assemblies to engineering drawings, BOMs, and work instructions Support system integration and high-pressure operations following released procedures and safety protocols; leak checks, proof testing, pressure system functional verification on feed system and COPVs Fabricate, bend, fit, and install precision tubing and fluid lines; perform and fitting operations to required standards Fabricate wire harnesses from assembly drawings and electrical schematics Collaborate closely with manufacturing, test, quality, and design engineering to resolve hardware issues in real time Follow detailed work instructions and manufacturing procedures, performing all work in the MES system (scanning, material consumption, and built traceability) Support setup of vacuum chamber for acceptance and performance testing Support receiving, inspection, and handling of COPVs Practice 5S principles of organizing and sustaining an efficient and presentable workspace Provide consistent process improvement feedback to engineering and production leadership Occasionally support vehicle integration…
