Energy Marshal

About the role

Ajax Building Company, part of the STO Building Group, is seeking an experienced, hands-on Energy Marshal to oversee the safe execution of energization and energy-isolation activities on mission critical data center projects.

Responsibilities

• Manage energy-control and commissioning activities from pre-energization through project completion and turnover.
• Develop, administer, and enforce the site-specific Lockout/Tagout (LOTO) program.
• Manage electrical-room access permits, access controls, and required room attendance.
• Conduct pre-energization inspections and verify that systems, documentation, and safety controls are complete before energization.
• Ensure compliance with established safe-work practices during energization, de-energization, testing, and isolation activities.
• Review and verify commissioning plans, energization plans, quality reports, and supporting documentation.
• Review, approve, and audit energy-isolation procedures for safety, accuracy, and compliance with project standards.
• Serve as the subject matter expert for energy isolation, providing technical guidance and support to project teams, trade partners, and other stakeholders.
• Attend daily and weekly High-Risk Activity (HRA) and Job Hazard Analysis (JHA) meetings, providing procedural support for work involving energy isolation.
• Interpret one-line diagrams, system drawings, and equipment redundancies to ensure LOTO procedures are properly designed and implemented.
• Provide guidance regarding the control of multiple energy sources, with particular emphasis on electrical systems.
• Verify the safe installation and energization of electrical equipment across multiple voltages, including AC and DC systems.
• Audit field practices against established procedures, written standards, and applicable safety requirements.
• Partner with project teams to identify risks, resolve issues, and implement continuous-improvement strategies.
• Clearly communicate technical requirements and energy-related concepts to both technical and nontechnical audiences.
• Exercise independent stop-work authority whenever unsafe energy-isolation or energization practices are identified.
• Participate in weekly project safety meetings and other required planning or coordination meetings.

Requirements

• Mission critical data center construction and commissioning experience required.
• 4+ years of direct experience in energy isolation, MEP systems, construction safety, commissioning, or a closely related field.
• 7+ years of commercial construction experience preferred, ideally in an Energy Marshal, Superintendent, MEP, commissioning, or electrical-safety role.
• Current NFPA 70E training or certification required.
• Strong knowledge of hazardous-energy control, LOTO procedures, energized electrical work, and electrical-safety practices.
• Familiarity with multiple energy sources and complex system redundancies, particularly within data center environments.
• Ability to read and interpret one-line diagrams, electrical drawings, system schematics, and commissioning documentation.
• Working knowledge of electrical equipment and systems across various voltages, including AC and DC systems.
• Demonstrated ability to audit site practices against written procedures, safety standards, and project requirements.
• Bachelor’s degree in Construction Management, Engineering, Occupational Safety, or a related field preferred; equivalent relevant experience will also be considered.
• Strong judgment and the confidence to independently stop work when unsafe conditions or practices are identified.
• Excellent communication skills, including the ability to explain complex technical concepts to engineers, field personnel, trade partners, and nontechnical stakeholders.
• Ability to collaborate across project teams and drive procedural and process improvements.
• Ability to lift more than 30 pounds when needed, climb ladders, and access confined or restricted areas to perform inspections and support equipment energization.
