PowerX is a multinational engineering and power infrastructure services company delivering protection, control, commissioning, NETA field services, and compliance support across the full lifecycle of power systems. The company operates across the United States and Canada with a people-first culture recognized by Great Place to Work and Fortune Best Workplace in Construction.
The P&C Senior Test Engineer is responsible for independent execution of testing, commissioning, and validation activities across transmission, distribution, and generation substations up to 765kV. This role operates with minimal supervision on assigned scopes and applies sound system-level understanding to protection testing. The Senior Test Engineer actively contributes to the development of less experienced team members and represents a critical developmental step between directed execution and full project ownership, building leadership habits, system-level awareness, and planning skills required to advance to Lead.
Key responsibilities include:
- Independently execute relay protection testing using industry-standard platforms (Doble, Omicron, RTS, SEL AcSELerator, GE Enervista, and equivalent systems)
- Test and validate protection elements including line, transformer, bus, feeder, breaker failure, reclosing, and transfer trip schemes under Lead oversight on complex configurations
- Perform and validate CT/PT testing including ratio, polarity, phasing, saturation characteristics, and single-point grounding verification independently
- Execute complete relay input/output testing, analog-to-digital metering checks, and individual element pickup and timing tests with accurate pass/fail determination
- Interpret relay logic, phasors, event reports, and oscillography to identify abnormal conditions and communicate findings clearly to the Lead
- Apply working knowledge of AC/DC power system fundamentals, complex power calculations, symmetrical components, relay element operation, protection zones and coordination philosophy, instrument transformer behavior, and overcurrent/differential/impedance/breaker failure protection applications
- Read, interpret, and navigate one-lines, three-lines, schematics, wiring diagrams, and control circuit documentation
- Support both greenfield and brownfield commissioning projects
- Work in operational substations and construction environments with exposure to outdoor weather, noise, vibration, heat, dust, oil, grease, and energized equipment
- Travel as required and work overtime and outage schedules as necessary
Requirements:
- Ability to lift up to 50 pounds
- Ability to work in operational substations and construction environments
- Ability to travel as required
- Ability to work overtime and outage schedules as necessary
- Exposure to outdoor weather conditions, noise, vibration, heat, dust, oil, grease, and energized equipment environments
- Technical competency in relay protection testing, power system theory, and protection coordination (specific years of experience and certifications not stated in excerpt)
