Overview
The AMHS track wiring and power-up scope typically includes, but is not limited to, the following work:
Installation, support, and termination of bus bar and conductor systems feeding Muratec OHT/OHS track segments.
Pulling and terminating 480V / 208V / 120V power feeders from designated panels to AMHS power supply units (PSUs) and track power injection points.
Low-voltage controls, communication, and signal cabling (CAN bus, Ethernet/Profinet, fiber where applicable) between track segments, controllers, OCS (OHT Control System), and host MES interfaces.
Grounding and bonding of track structure, support steel, and equipment per Muratec specs and NEC Article 250.
Coordination of cleanroom-compatible cable management, including UPW-rated cable tray, stainless hardware, and approved penetrations through cleanroom walls and ceilings.
Pre-energization checkout, megger testing, point-to-point continuity, phase rotation, and documented commissioning support alongside Muratec start-up engineers.
Safe energization (power-up) of track sections in coordinated sequence with Muratec, including LOTO management and arc-flash precautions.
Responsibilities
Field Leadership & Crew Management
Lead, schedule, and direct a crew of journeyman electricians, apprentices, and electrical foremen across multiple shifts as project demands.
Conduct daily pre-task planning (PTP) meetings, JSAs, and stretch-and-flex; ensure every crew member understands the day's scope, hazards, and quality expectations before entering the cleanroom.
Mentor and develop foremen and journeymen; identify training gaps and coordinate with the PM on corrective skill-building.
Manage labor productivity, track installed quantities against budget, and provide accurate weekly progress reporting to the PM.
Enforce gowning, contamination-control, and tool-control protocols at the cleanroom airlock and at all times within the controlled environment.
Technical Expertise & Subject Matter Authority
Serve as the on-site technical authority for AMHS electrical work, interfacing directly with Muratec field engineers, MEP design engineers, the owner's facilities team, and the GC.
Read and interpret Muratec OHT/OHS installation drawings, single-line diagrams, panel schedules, ladder logic, and controls schematics; translate engineering intent into precise field execution.
Resolve field conflicts, RFIs, and scope ambiguities; drive technical decisions in real time without compromising safety, quality, or schedule.
Verify track segment power requirements, voltage drop calculations, feeder sizing, and overcurrent protection coordination match approved drawings before any installation begins.
Lead troubleshooting on energized and de-energized systems - power quality issues, comm faults, ground loops, intermittent track faults - using meggers, oscilloscopes, multimeters, and clamp meters.
Cleanroom Protocol & Contamination Control
Champion cleanroom discipline: garmenting, glove protocol, tool wipedown, material staging, and approved ingress/egress procedures.
Ensure all materials entering the cleanroom are wiped down, certified, or otherwise approved per the site's contamination control plan (CCP).
Coordinate with the cleanroom certification team to maintain ISO classification during active electrical installation; understand the impact of cutting, drilling, and cable pulling on particle counts.
Use only cleanroom-compatible tools, lubricants, and consumables; reject any non-approved materials at the airlock.
Train and re-train crew on protocols whenever new personnel rotate onto the project.
Safety Leadership
Own the electrical safety program for the scope: enforce NFPA 70E compliance, arc-flash PPE selection, approach boundaries, and energized work permits where applicable.
Manage Lockout/Tagout (LOTO) program for the AMHS scope, including group lockout coordination during multi-trade interface work and Muratec commissioning.
Conduct and document daily safety inspections; lead near-miss and incident investigations with root cause analysis and corrective actions.
Reinforce slip/trip/fall awareness, ladder safety, scaffold and lift operation, and overhead work protocols - all elevated risks given AMHS track is overhead-mounted work.
Maintain a visible, vocal safety presence: stop work without hesitation when conditions warrant, and back the crew when they do the same.
Quality Assurance & Documentation
Verify every termination, splice, and pull against the approved drawings and Muratec installation specifications before sign-off.
Maintain installation records, megger logs, torque records, continuity checks, and as-built redlines daily - not at the end of the project.
Lead pre-energization walkdowns with QA/QC, the owner, and Muratec representatives; close out punch lists promptly.
Document and escalate non-conforming work to the PM with proposed remediation; never bury a quality issue.
Support commissioning documentation: power-up sequence records, factory-acceptance test (FAT) and site-acceptance test (SAT) participation, and final turnover packages.
Coordination & Communication
Interface daily with the GC, MEP coordinator, BIM team, and other trades (mechanical, controls, AMHS mechanical install, ceiling grid, fire protection) to manage track-overhead congestion and sequencing conflicts.
Lead weekly look-ahead planning with the PM; identify constraints, material needs, and prerequisite work two to three weeks in advance.
Communicate clearly and professionally with Muratec engineers - many of whom may be working through translation; use drawings, photos, and concise written confirmation to eliminate ambiguity.
Provide accurate, timely status updates to the PM and client representatives; flag risks early.
Qualifications
Experience
Minimum 10 years of commercial/industrial electrical experience, with at least 5 years in a foreman or general foreman role.
Minimum 3 years of direct experience working in semiconductor fab or equivalent ISO-classified cleanroom environments (ISO Class 4-6 / Class 10-1000).
Demonstrated experience installing, terminating, and powering up AMHS systems - Muratec, Daifuku, MECS, or equivalent OEM track systems strongly preferred.
Prior experience leading crews of 8 or more electricians on tool install, hookup, or fab construction projects.
Licensing & Certifications
Active Journeyman or Master Electrician license in the project state (or ability to obtain reciprocity within 30 days of hire).
OSHA 30 (Construction) - current.
NFPA 70E Qualified Electrical Worker - current within the last 3 years.
First Aid / CPR / AED - current.
Forklift, scissor lift, and aerial work platform (AWP) certifications.
LOTO Authorized / Qualified Person training.
Cleanroom gowning certification (or willingness to complete site-specific certification on day one).
Technical Skills
Expert-level ability to read and interpret electrical single-lines, panel schedules, conduit and cable schedules, controls schematics, and OEM equipment drawings (Muratec drawings often originate in Japanese - ability to navigate translated documents efficiently is required).
Strong working knowledge of NEC, with particular fluency in Articles 250 (Grounding), 300 (Wiring Methods), 408 (Switchboards/Panels), and 670 (Industrial Machinery).
Hands-on proficiency with megger, multimeter, clamp meter, phase rotation meter, ground resistance tester, and basic oscilloscope.
Familiarity with low-voltage controls, industrial communication protocols (Ethernet/IP, Profinet, CAN, fiber), and cable testing tools (Fluke DSX or equivalent).
Working knowledge of bus duct / bus bar systems, cable tray, and EMT/RMC conduit installation in cleanroom-compatible configurations.
Comfortable with construction technology: BIM 360 / Procore / Bluebeam, Microsoft Office, and digital documentation workflows.
Personal Attributes
Calm under pressure: cleanroom and AMHS commissioning happens on tight, owner-driven schedules with significant cost-of-delay; the right person solves problems instead of escalating them.
Disciplined communicator: writes clear emails, confirms verbal agreements in writing, and documents thoroughly.
Safety-first mindset, every day, no exceptions - visible and vocal.
Mentorship orientation: develops the next generation of foremen and journeymen rather than hoarding knowledge.
Respects cleanroom discipline and OEM protocols even when they slow the work down.
Preferred Qualifications
Direct prior experience on Muratec OHT/OHS installations at major semiconductor sites (Intel, Micron, TSMC, Samsung, GlobalFoundries, TI, etc.).
Experience working with Japanese or Korean OEM engineering teams; cultural awareness and patience with translation-driven communication.
Battery plant, lithium cell manufacturing, or pharmaceutical cleanroom experience (transferable contamination-control discipline).
PLC familiarity (Allen-Bradley, Siemens, Mitsubishi) sufficient to support troubleshooting at the controls interface.
Bilingual English / Japanese, English / Korean, or English / Spanish a plus.
Physical Requirements & Working Conditions
Ability to wear full cleanroom garments (bunny suit, hood, booties, double gloves, safety glasses, mask) for full shifts.
Comfortable working at heights from scissor lifts, articulating booms, and rolling scaffolds - AMHS track work is overhead, all day.
Ability to lift up to 50 lbs occasionally, stand and walk for extended periods on hard floors, and work in confined or congested overhead spaces.
Tolerance for cleanroom temperature, humidity, and noise conditions, and for rotating shift work (days, nights, or weekends) as the project requires.
Travel: this role is typically project-based; willingness to relocate or work extended per diem assignments at the project site is required.
What Success Looks Like in This Role
In the first 90 days, the General Foreman will have built a productive, safety-conscious crew, established working relationships with the Muratec field team and the GC, and delivered the first track sections energized on schedule with zero recordable incidents and zero re-work. Through the life of the project, success means a clean turnover package, a satisfied owner, a Muratec team that wants to work with this person again, and a crew of electricians who are better at their craft than the day they started.
