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.
