Whether it's autonomous vehicles, life‑saving medical tech, next‑gen aerospace, or AI/cloud infrastructure - our integrated solutions don't just meet standards - they redefine them.

What You'll Do

The High Voltage Winding Technician is responsible for setting up and operating high voltage winding equipment used in the manufacture of medium- and high-voltage power transformers. This role requires a high level of workmanship, attention to detail, and process discipline to ensure conductor placement, insulation application, winding sequence, and dimensional integrity meet engineering and quality requirements.

This position is intended for experienced manufacturing personnel who will support initial factory ramp-up through precise execution, quality ownership, and successful completion of equipment and process training.

• Set up and operate high voltage winding machines in accordance with work instructions and engineering requirements.
• Wind conductors to required dimensions, turn counts, and build specifications.
• Monitor winding operations and make adjustments to maintain alignment, dimensional accuracy, and build integrity.
• Follow required winding sequences and workmanship standards throughout the build process.
• Apply, position, and inspect insulation materials in accordance with engineering drawings, work instructions, and winding specifications.
• Maintain required build sequence, spacing, clearances, and insulation integrity throughout winding.
• Inspect insulation materials for condition, fit, placement, and conformance prior to and during winding.
• Inspect conductors, insulation materials, and winding components prior to use.
• Verify winding dimensions, conductor alignment, insulation placement, spacing, and overall build quality during and after winding.
• Perform in-line dimensional inspection using standard metrology tools to verify winding dimensions, alignment, spacing, insulation placement, and conformance to specifications.
• Perform required in-line electrical conformance checks using standard electrical test equipment and document results in accordance with work instructions and quality requirements.
• Identify defects such as conductor damage, insulation irregularities, sequence errors, or dimensional non-conformance and take corrective action.
• Accurately log production data, material traceability, and quality yields into the ERP or production tracking system.
• Safely handle conductors, insulation materials, tooling, and wound components using appropriate lifting or handling equipment.
• Stage materials to support efficient workflow while maintaining organization and traceability.
• Perform routine equipment checks, daily safety inspections, and basic preventive maintenance.
• Maintain a clean and organized work area in accordance with company standards.
• Support stable output and minimize defects, scrap, or rework through disciplined execution and quality-focused workmanship.
• Assist in resolving routine process or equipment issues during ramp‑up.

What You'll Bring

• High School Diploma or GED required.
• 3+ years of experience in a manufacturing or industrial environment.
• Experience operating winding equipment, performing precision build work, or working in a quality-critical manufacturing environment.
• Ability to read and interpret technical drawings, work instructions, and production specifications.
• Basic proficiency with measurement tools such as calipers, rulers, gauges, and related inspection tools.
• Strong mechanical aptitude and attention to detail.
• Ability to identify and respond to process or quality issues.

How to Stand Out

• Associate degree (AAS) in Electrical Technology, Mechanical Technology, Mechatronics, or related field strongly preferred.
• Experience in transformer manufacturing, motor manufacturing, coil winding, or similar electrical equipment manufacturing.
• Experience applying insulation materials in a precision or quality-critical manufacturing environment.
• Experience working with engineered materials requiring repeatability, workmanship discipline, and dimensional control.
