PowerX is a multinational engineering and services firm specializing in power infrastructure lifecycle support, including protection and control systems, commissioning, NETA field services, and compliance across transmission, distribution, and generation substations in the US and Canada.
The P&C Senior Test Engineer is responsible for independent execution of testing, commissioning, and validation activities across substations up to 765kV. This role operates with minimal supervision on assigned scopes and applies system-level understanding to protection testing while actively contributing to the development of less experienced team members.
Key responsibilities include:
**Technical Execution:**
- 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 to the Lead
**System Knowledge:**
- Apply working knowledge of AC/DC power system fundamentals, complex power calculations, symmetrical components, and relay element operation
- Understand protection zones, coordination philosophy, instrument transformer behavior and application, and overcurrent/differential/impedance/breaker failure protection applications
- Read, interpret, and navigate one-lines, three-lines, schematics, wiring diagrams, and control circuit documentation
**Development & Collaboration:**
- Mentor and guide less experienced team members
- Support both greenfield and brownfield commissioning projects
- Identify and escalate anomalies before they become operational risks
- This role represents the critical developmental step between directed execution and full project ownership, building leadership habits, system-level awareness, and planning skills required to advance to Lead
**Physical Requirements:**
- Ability to work in operational substations and construction environments
- Ability to lift up to 50 pounds
- 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
**Requirements:**
The posting does not explicitly state years of experience, education level, or specific certifications required. However, the role assumes proficiency with relay protection testing platforms, understanding of power system protection theory, ability to interpret complex electrical drawings and relay logic, and demonstrated capability to work independently on technical commissioning activities.
