Join the power movement as a Contract Technician - Welding and Assembly

Join a cutting-edge team working to assemble, weld and test high precision electromechanical assemblies — critical to unlocking the future of clean energy. As a (TIG) Welder and Technician, you'll perform complex electromechanical assembly and in-house welding of large-scale metallic structures. This work will also include micro TIG welding on smaller component assemblies. This is a hands-on role in a fast-paced, highly collaborative environment, with a focus on quality, safety, and continuous improvement.

What you'll do:

Assemble electromechanical components per detailed work instructions, drawings, and wiring diagrams

Operate production, testing, and high-powered magnet equipment

Use calibrated mechanical tools (e.g., torque wrenches, micrometers, calipers)

Troubleshoot assembly issues and suggest process improvements

Perform precision soldering, wiring, epoxy potting, injection molding, and vacuum system work

Collaborate with engineers to refine processes and improve manufacturability

Weld metallic structures and tooling using GMAW, GTAW, SMAW, and other methods

Read and analyze blueprints, perform detailed measurements, and plan welding layouts

Use manual welding equipment to produce welds in various positions (flat, vertical, overhead)

Weld stainless steel and copper, including pressure-rated and critical applications

Participate in welding equipment qualifications and inspections

Provide design feedback on weld geometries and material choices

What we’re looking for:

High school diploma or equivalent

3+ years of experience in electromechanical or electrical/mechanical assembly

3+ years of welding experience with structural systems and tooling

Proficiency with a variety of hand tools, power tools, and measurement devices

Ability to read and interpret technical documents, blueprints, and schematics

Documented training or certifications in welding processes (e.g., GMAW, GTAW, SMAW)

Must-have requirements:

Ability to lift up to 50 lbs regularly

Perform activities such as stooping, typing, standing, and sitting for extended periods of time

Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics

Willingness to travel occasionally or do required nights/weekends/on-call
