Weld Technician

Karman Industries

Karman Industries is a Torrance-based thermal technology company building the backbone for giga-scale AI infrastructure. Founded by a team from SpaceX, Rocket Lab, and GE, Karman is moving beyond legacy cooling with the launch of the HPU (Heat Processing Unit)—a new category of thermal architecture designed for the 100kW+ rack era.

The HPU shrinks the exterior mechanical yard by up to 80% while reducing peak energy consumption by 10%+. Unlike traditional systems, the Karman HPU provides zero-water (WUE 0) cooling that ensures high-TDP GPUs and HBM4 memory stay at optimal thermal setpoints without throttling.

Founded in 2024, we’re a fast-growing team of passionate professionals dedicated to making a tangible impact on the future of humanity. We design, build, and test real hardware, and we lead with ownership: you’ll own your work from concept to hardware and help shape how we scale. Our values are Ownership, Performance Excellence, Radical Transparency, and Customer-Centricity.

Join us in our mission to transform the industry and contribute to a more sustainable world.

Weld Technician

We are seeking a skilled Weld Technician to join our manufacturing team. In this role, you will be responsible for a wide variety of fabrication work, ranging from heavy structural welding for large industrial equipment frames to high-precision, high-pressure pipe welding. You will work directly with our engineering team to transition new designs from prototypes into production-ready industrial hardware.

Responsibilities

• Perform a variety of high-precision welds, seamlessly transitioning between heavy structural steel fabrication and high-pressure pipe welding (ranging from structural skids to small-bore piping systems).

• Proficiently execute welds using GTAW (TIG) and GMAW/FCAW (MIG/Flux-Core) across various materials, including carbon steel, stainless steel, and specialty high-temperature alloys.

• Read and interpret complex engineering drawings, weld symbols, structural blueprints, and piping and instrumentation diagrams (P&IDs) with limited initial documentation.

• Deliver flawless, X-ray/NDT-quality welds adhering to strict industrial standards, including ASME Section IX (Pressure Piping) and AWS D1.1 (Structural Welding).

• Take ownership of full weldment preparation, including cutting, grinding, beveling, aligning, and rigging large hardware components into position.

• Partner closely with manufacturing, test, and development engineers to optimize designs for manufacturability (DFM) and provide continuous feedback on prototype assemblies.

• Maintain a pristine workspace and champion a rigid safety culture, adhering to industrial standards required for building high-energy, pressurized equipment.

Required Qualification

• Minimum 5+ years of hands-on professional experience as a combination pipe and structural welder in an industrial OEM, aerospace, oil & gas, or heavy equipment manufacturing environment.

• Documented experience or active certifications under ASME Section IX (6G/5G pipe position preferred) and AWS D1.1.

• Proven track record welding both thin-wall tubing and thick structural members, with deep knowledge of thermal distortion control and joint design.

• A high-agency operator with mission-critical discipline, accountability, and the ability to thrive in a fast-paced, prototype-to-production hardware environment.

• Ability to lift up to 50 lbs, maneuver around massive industrial frames, and work in various positions required for complex hardware assembly.

Preferred Qualifications

• Experience fabricating hardware for supercritical fluid loops, high-pressure heat exchangers, or high-temperature steam systems.

• Familiarity with non-destructive testing (NDT) methodologies, including dye penetrant, magnetic particle, or radiographic inspection prep.

• Basic rigging and overhead crane operation experience for manipulating heavy structural skids.
