System Startup & Commissioning
Lead startup, commissioning, and acceptance testing of electrical systems including medium voltage switchgear, low voltage switchgear, switchboards, motor control centers (MCCs), and variable frequency drives (VFDs). Support safe system energization and turnover to customers while ensuring all systems operate as designed.
Testing & Troubleshooting
Perform advanced electrical testing such as insulation resistance, contact resistance, relay testing, and functional verification. Diagnose and resolve complex system issues in real time while interpreting one-line diagrams, schematics, and control logic.
Planning & Execution
Review project scope, drawings, and testing requirements prior to execution to ensure readiness. Ensure proper setup, calibration, and use of all test equipment and make real-time technical decisions during commissioning and system energization activities.
Safety & Compliance
Ensure strict adherence to OSHA regulations, NFPA 70E standards, and company safety policies. Identify and mitigate electrical hazards in field environments while following proper energized work practices and arc flash safety requirements.
Reporting & Documentation
Prepare complete, accurate, and customer-ready field service reports documenting testing results, deficiencies, and corrective actions. Maintain clear and consistent communication with project stakeholders throughout the duration of field activities.
Continuous Improvement
Support ongoing improvement of field service processes and standards by sharing lessons learned and best practices. Maintain and expand technical knowledge related to evolving power system technologies and equipment.
Technical Knowledge (Required)
Strong understanding of medium voltage and low voltage power distribution systems is required, along with working knowledge of commissioning and testing procedures. Candidates must have experience interpreting electrical schematics, one-line diagrams, and control systems, as well as advanced troubleshooting and diagnostic capabilities.
Strong knowledge of NFPA 70E electrical safety requirements and OSHA electrical safety standards is expected. Familiarity with NETA testing standards, protective relays, control systems, and OEM equipment such as Siemens, Eaton, Schneider, and ABB is preferred.
Essential Duties and Responsibilities
Work primarily in the field at customer sites performing commissioning, startup, and testing activities. Lead advanced electrical diagnostics and troubleshooting efforts while interpreting technical drawings and specifications. Coordinate with project stakeholders in real time and mentor junior technicians. Ensure compliance with all safety standards, prepare detailed service and testing reports, and travel locally to support multiple project sites. Perform additional duties as assigned.
Qualifications
Candidates should have 5 to 10 or more years of experience in field service, commissioning, or electrical testing, along with experience working on medium and low voltage power systems. Proven ability to lead field projects independently is required.
