Spacecraft Fluids Systems Technician/Thermal Control

K2 Space•Los Angeles, CA

About The Position

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. As a Spacecraft Fluids System Technician, you will support assembly, integration, and test of pressurized systems at sub-assembly and vehicle level. The ideal candidate is a highly hands-on technician comfortable working across mechanical, electrical, and fluid systems in a fast-paced environment.

Experience operating forklifts, cranes, and heavy equipment
Strong communication skills with ability to communicate hardware and systems problems, and provide feedback on improving tooling processes and part design
Airframe & Powerplant License
Ability to obtain or current hold top secret/SCI security clearance

Responsibilities

Perform hands-on assembly of pressurized system hardware 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
Fabricate, bend, fit, and install precision tubing and fluid lines; perform orbital welding 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
Occasionally support COPV pressure testing and handling at vehicle level
Practice 5S principles of organizing and sustaining an efficient and presentable workspace
Provide consistent process improvement feedback to engineering and production leadership
Support vehicle integration operations and other related departments as needed
