About the Job

Requirements

  • A high school diploma or GED and 10 or more years of applicable experience with industrial or commercial field engineering in mission-critical facilities and electrical infrastructures are required.
  • In-depth knowledge of medium-voltage (over 1,000 V) and low-voltage (under 1,000 V) power-distribution sequence of operations is required.
  • The ability to isolate potential energy sources, including potential backfeeds, and perform absence-of-voltage verifications is required.
  • Knowledge of and certification in NFPA 70E is required.
  • Hands-on experience with startups, lockout/tagout, and absence-of-voltage verification is required.
  • Leadership experience in the electrical field, preferably overseeing commissioning, is required.
  • The ability to make decisions in high-pressure environments with condensed schedules is required.
  • Knowledge of construction techniques, terminology, and documentation, including the ability to interpret blueprints, electrical one-lines, and construction drawings, is required.
  • The role requires extended exposure to computer screens and extended periods of sitting.
  • The role requires reaching with hands or arms in any direction and finger dexterity to manipulate objects, such as using a keyboard.
  • The role requires listening to and understanding spoken information, communicating information verbally, reading and understanding written information, applying general rules to specific problems, and identifying and understanding another person's speech.

Responsibilities

  • Act as the technical authority for on-site electrical operations related to the large-scale mission-critical mechanical, electrical, and plumbing system, design, and functionality, supporting 24/7/365 on-site datacenter operations.
  • Manage the site's electrical energy-isolation program for mechanical, electrical, and plumbing energy, ensuring energy-isolation activities are coordinated and executed across assigned locations according to established policies and procedures.
  • Review procedures, job hazard analyses, and permits, and audit the electrical energy program for construction, commissioning, maintenance, and operations activities to ensure safe working conditions.
  • Work with construction and commissioning teams and other stakeholders to ensure safe conditions for testing and validating the installation, operation, and performance of mechanical, electrical, and plumbing systems.
  • Coordinate electrical energizations and de-energizations with other energy marshals and stakeholders.
  • Lead pre-energization and energization kickoff meetings before first-of-kind equipment or system energizations.
  • Understand the commissioning plan of record and commissioning specifications as they relate to equipment energization at the jobsite.
  • Advance electrical safety improvements on the job and in future designs.
  • Implement the site-specific Electrical Safety Plan.
  • Review near-energized-work scenarios and develop risk assessments to determine safe work practices for activities in energized environments.
  • Provide operational oversight through field presence during major commissioning or energy-isolation activities, including first-of-kind work, methods of procedure, medium-voltage operations, and activities affecting turned-over spaces.
  • Coordinate daily commissioning-team operations with the commissioning lead.
  • Participate in safety lockout/tagout inspections and audits.
  • Coordinate all lockout/tagout and outage requests with M.C. Dean Safety, the general contractor, the client, and affected vendors and subcontractors.
  • Coordinate energization requirements and potential impacts to the jobsite commissioning schedule.
  • Coordinate access and egress for access-controlled areas.
  • Train new and existing employees in energy-isolation processes and procedures, and train and verify the competency of individuals performing lockout/tagout by equipment type.
  • Attend and participate in daily commissioning meetings and weekly jobsite all-hands meetings.
  • Develop, review, and approve lockout/tagout permits.
  • Lead and attend M.C. Dean operational risk-management safety briefs with the commissioning team and vendors.
  • Ensure personal protective equipment, tools, and other necessary equipment are suitable for use.

Desired Qualifications

  • Strong experience operating and maintaining building mechanical, electrical, and plumbing systems, including power distribution, lighting, grounding, fire alarm, security, life safety, and controls systems.
  • Experience working with battery-backed-up and generator systems.
