If that’s you and this role fits, we want to hear from you.
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
