We have a Commissioning Engineer position available in our Biddeford, ME office. This individual will be responsible for commissioning transmission and distribution substation additions or modifications to ensure they are installed, function, and are energized correctly. The role serves as a safety net to correct any errors introduced by incorrectly engineered design packages, installation errors, or equipment failures before the equipment is energized and released for service.

Ultimately the Commissioning Engineer prevents errors from compromising the reliability of the T&D system and the safety of employees involved in operating the system. Senior Engineers train new engineers/technicians in relay testing, equipment testing and substation commissioning.

• Review specifications and engineering drawings to understand the purpose and functionality of the substation.
• Schedule installation and commissioning with subcontractors and customers.
• Provide safety analysis and proper equipment isolation procedures.
• Offer a day‑to‑day outage plan for customers.
• Develop detailed test procedures and sign‑off sheets for each piece of equipment.
• Monitor construction and be available to address technical questions during construction, installation, and testing.
• Identify and resolve design errors.
• Assist field crews and dispatch in developing proper sequence for switching and ensuring hold points for testing are incorporated.
• Directly witness or perform critical tests such as DC Functional Trip Testing prior to energization and in‑service.
• Direct crews during critical work junctures, typically during final commissioning just before and through initial energization.
• Acknowledge that substation modification is complete and functional, and formally hand it over to Dispatch for operation within its design limits.
• Support several capital projects simultaneously, rotating among jobs while monitoring test results and work to anticipate problems and gauge technical support needs.
• Expect extended hours/days in a row at a particular job site near project completion when equipment is ready for functional testing and energization.
• Develop and maintain strong working relationships with customers, demonstrating awareness of their needs, preferences, and time and financial constraints.
• Manage resources and services required to install electrical equipment.
• Show proven customer service, sales ability, and the ability to handle difficult situations with customers and achieve satisfaction.
• Assist in developing estimates for client proposals and further business development.
• Understand AC and DC elementary diagrams, wiring diagrams, and one‑line drawings to determine system operation and develop testing requirements and procedures.
• Develop standard testing documentation, training procedures, and maintain all project documentation including certifications and calibration records. Candidates should be able to obtain NICET certification or equivalent.
• The ideal candidate must have a diverse skill set, work independently, act as a technical lead on projects, and guide lower‑level engineers/technicians.

Bachelor’s degree in engineering (electrical, mechanical, or engineering technology) is preferred. An associate degree is acceptable provided the candidate has proven experience in the field.

3+ years with capabilities in the areas below is preferred:

• In‑depth understanding of:
  • Three‑phase power systems
  • Protection and control schemes and implementation
  • Equipment testing – circuit breakers, transformers, circuit switchers, MOABS, CTs, PTs, batteries and chargers, transfer switches, line tuners, wave traps, carrier relays, etc.
• Experience in:
  • Testing, troubleshooting, evaluating, and servicing electrical distribution and control systems is highly desirable
  • Util…
