Job summary

POWERX Co. is seeking a P&C Senior Test Engineer to independently execute testing, commissioning, and validation across transmission, distribution, and generation substations.

This role emphasizes system-level understanding of protection schemes and mentoring junior staff. You will work with leading protection platforms (Doble, Omicron, RTS, SEL AcSELerator, GE Enervista) and develop comprehensive test plans.

Qualifications

• Minimum 2+ years of experience in high-voltage Protection & Control testing and commissioning.
• Experience commissioning substations from 12.5kV through 765kV preferred.
• Experience with SEL, GE, ABB, Siemens, Westinghouse, or equivalent relay platforms.
• Bachelor’s degree in Electrical Engineering or Electrical Technology, or an Associate degree in Electrical Technology or related field experience preferred.
• OSHA 30 certification preferred.

Responsibilities

• 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.
• Develop complete test plans, isolation plans, energization plans, commissioning procedures, Human Performance mitigation plans, and job hazard analyses for assigned scopes independently, ensuring all documents reflect the full protection scheme and operational risk profile.
