POSITION SUMMARY The Supervisor, I&E - 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.

KEY RESPONSIBILITIES 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 maintain...
