Lead transformer commissioning and acceptance testing for complete substations, including energization planning and switching sequences. Direct transformer repair, overhaul, refurbishment and retrofit programs, including LTC overhaul and internal inspection. Lead transformer failure investigations, report findings, and recommend repair, refurbishment, retrofit, or replacement. Define transformer test plans, standards, and acceptance criteria for the region and support their inclusion in the Technical Qualification Program. Interface with engineering and OEMs on transformer design limits, loading, and warranty or return material authorization (RMA) determinations. Field & Program Leadership Provide technical leadership during outages, turnarounds, and critical recovery events; communicate status, risks, and mitigation plans. Direct testing activities and manage multiple work fronts; lead field crews, contractors, and junior engineers. Approve commissioning documentation and close out actions with customer sign-off. Mentor and supervise Field Service Engineers and technicians at Levels 1 through 4; review work quality and coach troubleshooting approach. Modernization & System Integration Lead equipment-level and system-level modernization, retrofit, and integration projects. Define execution strategies, risk mitigation plans, and field quality standards for complex programs. Interpret retrofit drawings, relay and control information, and confirm field readiness for execution. Direct corrective maintenance and repair activities, including breaker overhaul support, mechanism adjustments, alignment, lubrication, and component replacement. Safety Leadership Lead on-site safety briefings and enforce LOTO, arc-flash, energized work restrictions, job hazard analysis, and permit requirements. Lead root cause investigations, including high-potential safety events, and drive corrective and preventive actions. Standards, Process & Customer Enablement Develop and standardize field procedures, commissioning standards, and best practices; support development of the Technical Qualification Program. Coordinate with project managers, engineering, factory, and supply chain on parts identification, RMA/warranty, technical escalations, and root cause analysis. Produce high-quality field service reports, test records, punch lists, commissioning checklists, and nonconformance documentation. Deliver customer training and knowledge transfer on system operation, basic maintenance, and safety considerations. Identify modernization opportunities and communicate leads through the appropriate channels. Qualifications Required 11+ years of progressively responsible field experience with MV/HV switchgear, breakers, and protection and control systems; OR a Bachelor's or Associate's degree in an aligned discipline such as Electrical Engineering, Mechanical Engineering, Project Management, or a related technical field, combined with demonstrated field experience and technical competency equivalent to this level. Demonstrated ability to lead field crews and manage on-site execution for complex commissioning and service events. Strong working knowledge of electrical safety practices (NFPA 70E/OSHA or local equivalents), including LOTO and arc-flash risk controls. Proven experience reading, troubleshooting, and redlining schematics, wiring diagrams, and one-line diagrams. Demonstrated authority in transformer field testing and condition assessment, including interpretation of DGA and electrical diagnostic results against IEEE C57 criteria. Ability to develop commissioning and test plans, verify I/O, and perform functional checks from drawings and sequences of operation. Ability to write clear field reports and maintain accurate test documentation. Valid driver's license with an acceptable motor vehicle record, maintained throughout employment; ability to travel as required, sometimes on short notice. Must be at least 21 years of age to be assigned and operate a company-provided service vehicle. Must be able and willing to obtain Department of Transportation (DOT) non-CDL qualification, including a current DOT medical card where required for towing test trailers or oil-processing equipment, and comply with applicable DOT regulatory requirements. Preferred Experience commissioning digital protection relays and IEC 61850/GOOSE networks, where applicable. Certification or formal training in SFRA, partial discharge, or other advanced transformer diagnostic methods. Experience leading transformer failure investigations and refurbishment or retrofit programs.
