Spacecraft Fluids Systems Technician​/Thermal Control

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.

• 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 supportCOPV 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

• 3+ years of hands-on aerospace assembly and test experience in propulsion, pressure systems, fluid systems, or high-reliability hardware
• Experience with pressure testing, leak checking, proof/burst testing, or COPV handling
• Hands-on experience with tube fabrication, bending, and fitting (flare, AN, VCR, or similar fittings)
• Familiarity with MES/MRP software
• Familiar with calibrated tools including multi-meters, torque wrenches, safety cable guns, and crimpers
• Demonstrated high levelof ownership and problem-solving abilities
• Experience working with FOD, ESD sensitive hardware and clean room requirements

• Direct experience with aerospace propulsion system sand familiarity with pressure testing, vacuum chambers, turbo pumps, roughing pumps, gauges
• Ability to read mechanical and engineering drawings and interpret tolerances (including GD&T)
• Experience working with engineering teams in…
