• Coordinate with engineering, construction, and client teams to resolve technical issues, clarify design requirements, and support project planning.

• Develop or refine commissioning test plans and procedures to ensure project-specific scopes are executed thoroughly and consistently.

• Maintain accurate and timely documentation, including test reports, relay settings verification, redlines, daily logs, timesheets, and expenses.

• Support startup and energization planning, including outage coordination, equipment readiness checks, and safety walkdowns.

• Provide mentoring and technical guidance to junior technicians and commissioning support staff.

• Experience creating and executing commissioning test plans, FAT/SAT procedures, and turnover documentation.

• Solid understanding of NERC PRC-005-6, equipment maintenance standards, and best practices for work in high-voltage substations.

• Ability to interpret and evaluate engineering drawings, relay settings, and electrical logic diagrams with high attention to detail.
