Senior Field Service Engineer

Key Responsibilities
Technical Authority & Commissioning

• Lead commissioning and startup of complete electrical systems, including acceptance testing and verification of system performance.
• Serve as the primary technical escalation point for advanced control, protection, and integration issues.
• Plan and perform advanced diagnostics for equipment and protection/control issues, including intermittent faults and complex system interactions.
• Perform protection relay commissioning and end-to-end verification; validate settings implementation against approved setting files and drawings.
• Execute and direct acceptance, maintenance, and condition-based testing (insulation resistance, contact resistance, timing/travel analysis, primary and secondary injection, relay logic verification, SCADA/RTU I/O checks).

• Serve as the technical authority for transformer condition assessment and failure investigation.
• Plan and perform advanced transformer diagnostics including sweep frequency response analysis (SFRA), dielectric frequency response (DFR), leakage reactance / short-circuit impedance, partial discharge, and advanced insulation power factor testing.
• Assess transformer condition by trending electrical test data, oil analysis (DGA, moisture, furan), and inspection findings against factory acceptance, commissioning, and historical baselines.
• Diagnose complex transformer faults including overheating, abnormal gassing, bushing degradation, winding deformation, and load tap changer failures.
• 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.

• 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.

• 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.

• 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.

• 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.

• 11+ years of progressively responsible field experience with MV/HV switch gear, 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…
