• Lead active part assembly operations for liquid-filled distribution transformers in accordance with engineering drawings, bills of material, and work instructions
• Position and secure coils to the transformer core using approved methods, tools, fixtures, and assembly practices
• Perform upper yoke assembly, including installation and alignment of the top section of the core after coils have been placed over the core limbs
• Install coil wedges and specialized insulation materials required to secure coils against the core and maintain assembly stability
• Verify active part fit-up, alignment, and assembly readiness throughout the build process
• Support development and refinement of standard work and best practices for active part assembly operations during ramp-up
• Route, position, secure, and connect internal coil leads in accordance with engineering drawings and work instructions
• Verify lead placement, routing, clearances, and connection conformance throughout the active part assembly process
• Ensure internal lead connections are completed in a manner that supports assembly integrity, insulation protection, and downstream manufacturing requirements
• Identify lead-routing or connection issues and take corrective action in accordance with standard procedures
• Inspect core components, coils, insulation materials, wedges, leads, hardware, and related materials prior to use for condition, completeness, and conformance
• Verify coil positioning, upper yoke alignment, wedging condition, lead routing, and overall active part assembly integrity throughout the build process
• Perform in-process dimensional and visual checks using standard measurement and inspection tools in accordance with work instructions
• Identify defects such as poor fit-up, damaged insulation, improper wedging, lead-routing issues, missing hardware, or non-conforming assembly conditions and take corrective action
• Accurately log production data, material traceability, and quality yields into the ERP or production tracking system
• Identify recurring assembly or quality issues and support corrective actions to improve consistency and reduce rework
• Safely handle cores, coils, active part components, insulation materials, wedges, leads, hardware, and related materials using appropriate lifting or handling equipment
• Use overhead cranes, hoists, fixtures, and other approved devices as required
• Stage materials and assembly aids to support efficient workflow while maintaining organization and traceability
• Use hand tools, power tools, fixtures, assembly aids, and related equipment required for active part assembly operations
• Perform routine equipment and tool checks and report issues as needed
• Support troubleshooting of equipment, tooling, or process issues as required
• Maintain a clean and organized work area in accordance with company standards
• Support training and qualification of new operators during factory ramp-up
• Share active part assembly best practices, workmanship expectations, and quality standards with team members
• Assist supervisors in identifying process gaps, training needs, and improvement opportunities
• Interface with upstream winding, core preparation, and downstream tanking/final assembly operations as required by production flow

What You'll Bring

• High School Diploma or GED required
• 5+ years of experience in a manufacturing, industrial, or assembly environment
• 3+ years of experience in transformer active part assembly, transformer pre-assembly, core and coil assembly, or similar heavy electrical manufacturing environments
• Prior experience supporting equipment readiness, process stabilization, or operator training in a quality-critical manufacturing environment preferred

How to Stand Out

• Associate degree (AAS) in Electrical Technology, Mechanical Technology, Mechatronics, Industrial Technology, or related field strongly preferred
• Experience in liquid-filled transformer manufacturing or similar heavy electrical manufacturing environments
• Experience with core and coil assembly, upper yoke assembly, coil wedging, insulation placement, or related active part manufacturing operations
• Experience supporting process improvements, operator training, startup activities, or process documentation in a quality-critical environment
• Demonstrated ability to lead by example in quality, safety, and execution
