Supervisor, Maintenance (I&E High Voltage)

The I & E Supervisor (High Voltage) leads a specialized team of instrumentation and electrical technicians responsible for the safe operation, maintenance, and testing of medium- and high-voltage electrical equipment across midstream facilities. Beyond day-to-day supervision, this role carries a strategic mandate: to build and grow an in-house high-voltage testing capability by transitioning the team from writing permits and coordinating third-party testing contractors toward directly performing medium- and high-voltage electrical testing. The successful candidate will assess current team capabilities, develop technician skills and qualifications, standardize testing procedures and equipment, and progressively reduce reliance on external testing contractors — all while strengthening equipment reliability, personnel safety, and regulatory compliance. Responsibilities include, but are not limited to: Leadership & Team Development Lead, coach, and develop a team of high-voltage I&E technicians; set performance expectations, provide feedback, and build long-term bench strength. Assess current team capabilities against the skills required to perform MV/HV testing, and build a structured training, qualification, and mentoring roadmap. Grow the group as scope and staffing expand; foster a culture of ownership, safety, and accountability. Provide training and technical support to technicians and cross-functional partners. Electrical Equipment Testing Capability Establish standardized testing procedures, methods, and acceptance criteria aligned with NETA MTS and NFPA 70B condition-based maintenance practices. Develop a standardized equipment testing program — insulation resistance, power factor / tan delta, VLF, transformer turns ratio, contact and winding resistance, and protective relay testing (primary and secondary injection). Develop technician qualification programs so all testing is performed safely by qualified personnel under a clear competency standard. Progressively reduce reliance on external testing contractors while maintaining reliability, safety, and schedule, retaining contractor support strategically where it makes sense. Maintenance, Reliability & Compliance Oversee installation, troubleshooting, testing, and maintenance of MV/HV equipment — substations, switchgear, breakers, transformers, protective relays, substation and branch feeders, variable frequency drives, and associated controls. Implement and maintain preventive and condition-based maintenance programs, aligning PM intervals with NFPA 70B. Champion electrical safety; ensure compliance with NFPA 70E and applicable codes, proper permitting, lockout/tagout, and safe work practices. Interpret and maintain P&IDs, one-line diagrams, and complex electrical drawings; ensure drawings and documentation are kept current. Planning & Coordination Coordinate and prioritize testing and maintenance activities with Operations to maximize equipment availability and minimize unplanned downtime. Plan and schedule outages, turnarounds, and testing campaigns; manage workload, priorities, callouts, and overtime. Support budget development and cost control, capturing savings as in-house capability reduces contractor spend. Communicate effectively with technicians, Operations, Engineering, and third-party stakeholders at all levels of the organization.
