The HPU is built around a supercritical CO2 chiller system utilizing a high-speed electrically driven turbomachinery core. Our system aims to reduce energy consumption in data center thermal management by greater than 25% and increase energy density by 10x.

At Karman Industries, we are committed to fostering a dynamic and inclusive work environment where innovation thrives. Our team is composed of passionate professionals dedicated to making a tangible impact on the future of industrial manufacturing. 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.
