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 mai...
