What you will be doing

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

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 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.

Qualifications – Required

What your background should look like (minimum qualifications)

• High school diploma or G.E.D. equivalent.


• Minimum 7+ years of electrical and instrumentation experience, including medium- and/or high-voltage equipment, preferably in an energy-related industry.


• Minimum 2+ years in a supervisory, lead, or crew-leadership role, or demonstrated leadership of technical teams.


• Thorough knowledge of electrical codes and familiarity with AC voltage (120–480V) three-phase and single-phase plus 24 VDC; working knowledge of medium- and high-voltage systems.


• Working knowledge of NFPA 70E electrical safety practices.


• Ability to read and interpret P&IDs, one-lines, blueprints, work permits, and technical instruction manuals.


• Basic computer skills (MS Word, Excel) for creating and updating work records and reports.


• Valid driver’s license and acceptable driving record.

Qualifications – Preferred

• Graduation from a technical trade school, apprenticeship, certification, or associate degree program in instrumentation, electrical, or related studies.


• Journeyman electrical designation highly preferred.


• Hands-on MV/HV electrical testing experience (insulation resistance, power factor / tan delta, VLF, TTR, contact resistance, protective relay testing).


• Familiarity with NETA testing standards and NFPA 70B condition-based maintenance.


• Experience building, scaling, or insourcing a testing program or maintenance team.


• Experience with DCS/PLC systems, VFDs, protective relaying, and substation equipment.

Attributes

• Takes initiative, is proactive in addressing issues, and completes tasks efficiently.


• Communicates effectively in writing and verbally, and adapts style to influence, persuade, negotiate, and engage.


• Assumes responsibility, prioritizes, and responds to multiple tasks under potentially stressful and/or hazardous conditions.


• Demonstrates conscientiousness, dependability, and commitment to the role, team, and company; works effectively in a fast-paced environment with less definition, policy, and bureaucracy.
