Description
Apply electrical engineering principles to assist in the design, integration, testing, commissioning, and maintenance of power distribution, control, and building electrical systems. Develop drawings and calculations, troubleshoot equipment, implement modifications, and document results to support reliable, efficient, and code-compliant operation under the direction of engineering staff.
Job tasks Attributes
  • • Replace defective electrical components or parts using hand tools and precision test instruments.
  • • Set up and operate electrical and power-quality test equipment to diagnose or analyze system performance.
  • • Read blueprints, one-line diagrams, wiring schematics, and engineering instructions for assembling or installing electrical systems.
  • • Identify and resolve equipment malfunctions, coordinating with manufacturers or vendors to procure replacement parts.
  • • Assemble electrical panels, control cabinets, or prototypes using hand tools and measuring instruments.
  • • Review electrical engineering plans for adherence to design specifications and applicable codes and standards (e.g., NEC, NFPA, IEEE).
  • • Assemble, test, or maintain circuits or electrical components according to engineering instructions or technical manuals.
  • • Review and update electrical design criteria, standards, or procedures to remove outdated material.
  • • Maintain system logs, test reports, and operation manuals to document commissioning and maintenance activities.
  • • Select electrical equipment, components, or systems—such as transformers, switchgear, breakers, or VFDs—to meet functional specifications.
  • • Perform load calculations, voltage drop and short-circuit checks, and prepare cost, material, and resource estimates, schedules, and budgets.
  • • Train operators or maintenance staff on the proper use and care of electrical equipment.
  • • Supervise or support the installation, startup, and commissioning of electrical and control systems.
  • • Compile and maintain records of schematics, installed equipment, field issues, resources used, repairs, and corrective actions.
  • • Modify prototypes, panels, or systems to correct functional deviations or improve performance.
  • • Integrate hardware and software for automation, using PLCs, HMIs, or SCADA architectures.
  • • Procure parts, manage inventory, and maintain related documentation.
  • • Participate in training or continuing education to stay current with electrical codes, tools, and technologies.
  • • Research equipment or component needs, sources, pricing, lead times, and lifecycle or operating costs.
  • • Provide engineering support and recommendations for new or existing systems regarding installation, upgrades, or enhancements.
  • • Plan, coordinate, or conduct quality control and acceptance testing procedures.
  • • Produce electrical, control, and instrumentation drawings using computer-aided design (CAD) software.
  • • Install, program, or maintain electrical control systems, motor controls, variable frequency drives, and programmable logic controllers.
  • • Design or modify schematics, single-line diagrams, and layouts for power distribution in residential, commercial, or industrial facilities using CAD.
  • • Interpret test results and field data to resolve design-related or operational problems.
  • • Conduct cost or statistical analyses to compare alternative designs, retrofits, or maintenance strategies for sustainability and efficiency.
  • • Support development, testing, or deployment of energy-efficient lighting, power management, or renewable integration projects.
  • • Develop, review, or prepare preventive maintenance standards and procedures.
  • • Assist with protective device coordination activities, arc-flash data collection, and equipment labeling.
  • • Modify, maintain, or repair electrical equipment or systems to ensure proper functioning.
