P&C Senior Test Engineer

Job Summary: 

The P&C Senior Test Engineer is responsible for the independent execution of testing, commissioning, and validation activities across transmission, distribution, and generation substations. This role operates with minimal supervision on assigned scopes, applies sound system-level understanding to protection testing, and actively contributes to the development of less experienced team members. 

The P&C Senior Test Engineer understands not only how to execute individual protection tests but also how the tested components interact as a complete protection system. This includes CT/VT theory and application, relay logic interpretation, control circuit verification, drawing navigation, and the ability to identify and escalate anomalies before they become operational risks. 

This role is the critical developmental step between directed execution and full project ownership. The Senior Test Engineer is building the leadership habits, system-level awareness, and planning skills required to advance to Lead. This position supports greenfield and brownfield commissioning projects involving relay protection systems, SCADA integration, breaker controls, transformer protection, and bus protection across substations up to 765kV. 

 

Supervisory Responsibilities: 

•  None. 

 

Duties/Responsibilities: 

Technical Knowledge 

• Independently execute relay protection testing using Doble, Omicron, RTS, SEL AcSELerator, GE Enervista, and equivalent testing platforms. 

• 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 and complex power calculations, symmetrical components and relay element operation, protection zones and 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, logic diagrams, cable schedules, and panel layouts with ease. 

• Identify station phasing and equipment orientation from any location in the substation. 

• Support switching activities and outage coordination independently; prepare projects through final pre-energization readiness with Lead oversight required prior to actual energization. 

• Treat every testing scope as a system validation exercise, not an isolated component check. 

• Technical Development 

• Actively engage with internal training material at the advanced levels and apply that learning directly to field assignments and commissioning scopes. 

• Develop complete test plans, isolation plans, energization plans, commissioning procedures, Human Performance mitigation plans, and job hazard analyses for assigned scopes independently, e
