Job Description — Energy Marshal (LOTO / PTW)

Position Summary

The Energy Marshal supports safe, compliant, and efficient execution of construction, pre-commissioning, and start-up activities on a semiconductor fabrication (fab) project. This role serves as the central coordination point for all energy control activities impacting construction and tool hook-up work—spanning electrical, mechanical, hydraulic, pneumatic, chemical, gas, and stored energy sources.

Working closely with Construction Management, Quality Assurance/Quality Control (QA/QC), Commissioning (Cx), and Operations/Facilities, the Energy Marshal manages isolations, lockout/tagout (LOTO), and permit-to-work (PTW) processes to enable safe work in a complex, high-tech environment.

Key Responsibilities

1) Energy Control & Safety

• Lead implementation and enforcement of Energy Control Procedures (ECPs) and LOTO programs for all construction and commissioning activities within the fab and supporting facilities.
• Identify, verify, and document all energy sources, including but not limited to:
• • High/medium/low voltage electrical systems
  • Process gases and ultra-high purity (UHP) gases
  • Chemicals and chemical distribution
  • Vacuum, compressed air, water, thermal systems
  • Stored mechanical energy and other hazardous energy sources
• Ensure isolations, locks, tags, and zero-energy verification are in place, validated, and documented prior to starting work.
• Coordinate safe energization/de-energization of equipment, tools, and systems (e.g., substations, distribution boards, temporary power, exhaust systems, process utilities).
• Maintain strict controls for live work, troubleshooting under power, and deviations from standard isolation practices—ensuring required approvals, controls, and documentation.
• Conduct field verifications, pre-job walkdowns, and support job hazard analyses (JHAs) for energy-intensive tasks (tie-ins, tool hook-ups, turnovers, cutovers, start-ups).

2) Permitting & Work Authorization (PTW)

• Review, authorize, and track permits involving energy hazards, including:
• • Electrical work and HV/MV switching
  • Hot work in cleanroom/support areas
  • Confined space entry (pits, tanks, sub-fab areas)
  • Work on process gases, chemicals, and other hazardous energy systems
• Coordinate work windows, isolations, and clearances with Construction, trade contractors, Commissioning, and Facilities/Operations.
• Ensure robust documentation and traceability including isolation plans, LOTO logs, switching orders, red-line drawings, and permit closeout records.
• Verify removal of locks/tags and safe restoration of systems to service upon completion, including permit closeout and turnover readiness.

3) Coordination & Communication

• Act as the single point of contact and “source of truth” for energy status within assigned areas (e.g., sub-fab, cleanroom, central utility building).
• Participate in daily SIMOPS planning, PTW meetings, and coordination calls to align schedule, work fronts, and energy-related constraints.
• Communicate energy status, planned shutdowns, start-ups, and isolation changes to impacted contractors and client teams.
• Escalate and resolve conflicts (overlapping scopes, competing shutdowns), unsafe conditions, or deviations from procedure—driving alignment across stakeholders.

4) Compliance & Documentation

• Ensure compliance with company policies, client standards, and applicable regulations/codes (e.g., OSHA 1910/1926, NFPA 70E, NFPA 70/NEC, relevant SEMI standards).
• Maintain current and accurate energy control documentation, such as:
• • Energy status boards
  • One-line diagrams
  • P&IDs and utility drawings
  • Isolation lists and red-lined drawings reflecting field conditions
• Support internal/client audits, inspections, and incident investigations related to energy control, LOTO, and PTW.
• Contribute to development and continuous improvement of fab-specific ECPs, LOTO standards, and switching/turnover plans.

5) Training & Safety Culture

• Coach supervisors, foremen, and technicians on proper energy isolation, LOTO, and permit compliance—especially personnel new to fab environments.
• Deliver or support training in energy awareness, electrical safety, process gas/chemical hazards, and semiconductor-specific energy risks.
• Promote strong safety culture through hazard identification, near-miss reporting, and active use of stop-work authority for energy-related concerns.

Requirements

7+ years of experience in industrial construction, semiconductor construction, power/utility systems, or process plant environments (pharma, chemical, oil & gas, data centers, etc.).

• Demonstrated experience leading or coordinating LOTO and energy isolation programs on large, complex projects.
• Working knowledge of:
• • Electrical distribution: HV/MV/LV, switchgear, MCCs, panels
  • Mechanical/utility systems: chilled water, DI water, CDA, vacuum, exhaust
  • Hazardous gases/chemicals typical to semiconductor fabs (e.g., toxic/pyrophoric gases, acids, solvents) or strong willingness to learn quickly
  • Process piping, pipefitting, welding; familiarity with WWT and UPW systems is highly valued
• Ability to read and interpret one-line diagrams, P&IDs, utility layouts, and construction/commissioning procedures.
• Strong communication and coordination skills across multiple contractors and disciplines.
• Proficiency with basic digital tools (MS Office) and willingness to use digital PTW/LOTO systems.
• • Direct semiconductor fab experience (greenfield, brownfield, tool install, major expansion).
  • Prior role as Energy Marshal, LOTO Coordinator, PTW/Permit Coordinator, Authorized Person, or Electrical/Utilities Safety Officer.
  • Certifications/training such as:
  • • NFPA 70E Electrical Safety
    • OSHA 30 (Construction); OSHA 50 or equivalent
    • High-voltage switching or substation operations training
    • HAZCOM / process safety / hazardous materials training
• Experience working in cleanroom/sub-fab environments; understanding of contamination controls, access controls, and gowning protocols.

Competencies

• Strong safety mindset with a high sensitivity to hidden/complex energy sources.
• High attention to detail and disciplined execution of procedures and documentation.
• Ability to influence and hold multiple contractors accountable without direct line authority.
• Skilled at prioritizing and managing multiple simultaneous work fronts and shutdown windows.
• Clear, concise verbal and written communication; comfortable leading briefings and coordination meetings.

Working Conditions

• Primarily field-based on an active construction and commissioning site, including sub-fab, utilities areas, and cleanroom spaces (with appropriate gowning).
• Exposure to construction noise, working at heights, confined spaces, and high-voltage/hazardous materials with appropriate PPE and controls.
• May require shift work and extended hours (nights/weekends) to support critical tie-ins, shutdowns, and commissioning milestones.
• Occasional travel to other project sites or client locations as required.

Benefits

What Makes This Opportunity Different

This isn’t a volume-hiring environment. We are a high-performing, reputation-driven team known for delivering elite execution in complex, high-stakes projects. As a small, family-oriented company, we prioritize how people are treated—while maintaining uncompromising standards for safety, quality, and professionalism. We are selective and intentionally hire only individuals who are recognized leaders in their craft and who align with a culture built on integrity, respect, and accountability.
