Job description

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 will perform complex electromechanical assembly and in‑house welding of large‑scale metallic structures. This work also includes 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

$35 - $43 an hour. This is a contract position.
