About the role

Job Summary

NTS is seeking an experienced
Senior Protection Engineer to lead the design, application, testing, and
commissioning of protection and control systems for power transformers and
substation equipment. This role serves as a technical authority for protective
relaying on customer projects, mentors junior engineers, and works closely with
field service, testing, and project management teams to deliver safe, reliable,
and code-compliant solutions for utility and industrial clients.

Key Responsibilities

• Design, specify, and review protection and control
schemes for power transformers, substations, and associated equipment (relays,
CTs/PTs, breakers, reclosers).

• Develop protective relay settings and coordination
studies, including short-circuit, load flow, and arc-flash analysis.

• Program, configure, and test microprocessor-based
protective relays (SEL, GE, ABB, Siemens, and similar platforms).

• Lead commissioning, functional testing, and
troubleshooting of protection schemes in the field and factory acceptance
testing (FAT).

• Review and interpret one-line diagrams, three-line
diagrams, schematics, and wiring drawings for accuracy and code compliance.

• Investigate relay misoperations and equipment failures;
perform root-cause analysis and recommend corrective actions.

• Ensure designs comply with NERC, IEEE, ANSI, NEC, and
applicable utility and client engineering standards.

• Provide technical guidance and mentorship to associate
and staff protection engineers and field technicians.

• Collaborate with project managers, sales, and clients
to scope work, develop proposals, and support project schedules and budgets.

• Prepare clear technical documentation, including test
reports, settings files, studies, and as-built records.

• Support continuous improvement of engineering
standards, templates, and quality assurance procedures.

• Travel to customer sites, substations, and project
locations as needed to support testing and commissioning activities.

Required Qualifications

• Bachelor's degree in Electrical Engineering or a
related field (or equivalent combination of education and experience).

• Minimum of 7 years of experience in power system
protection engineering, including transformer and substation protection.

• Demonstrated expertise with protective relay
programming and testing using tools such as SEL AcSELerator, DOBLE, Omicron
Test Universe, or equivalent.

• Strong working knowledge of protection principles,
including differential, overcurrent, distance, and busbar protection schemes.

• Familiarity with NERC PRC standards, IEEE C37 series,
and utility protection and control practices.

• Ability to read and interpret electrical schematics,
one-lines, and relay logic diagrams.

• Strong analytical, troubleshooting, and communication
skills, with the ability to explain technical issues to non-technical
stakeholders.

• Valid driver's license and ability to travel to project
and customer sites, including occasional overnight travel.

Preferred Qualifications

• Professional Engineer (PE) license, or ability to
obtain licensure within a defined timeframe.

• Experience with short-circuit, coordination, and
arc-flash software (ETAP, ASPEN, CAPE, SKM, or similar).

• Prior experience working with or for a utility,
transformer service provider, or substation construction/testing organization.

• Experience with SCADA, RTUs, and substation automation
and communications protocols (DNP3, IEC 61850).

• NETA certification or equivalent field testing
credentials.

Work Environment & Physical Requirements

• Work is performed in a combination of office and
field/substation environments, including energized electrical environments.

• Must be able to wear and work in appropriate personal
protective equipment (PPE), including arc-flash rated clothing.

• Ability to lift up to 25 lbs., climb ladders, and work
outdoors in varying weather conditions as needed for field assignments.

• Field travel typically ranges from 10–25%, depending on
project workload.
