Job Description:

The Facilities Electrical Engineer is responsible for the design, operation, and 100% uptime of the high-voltage and medium-voltage power distribution systems supporting a 24/7 semiconductor manufacturing environment. This role ensures the "mission-critical" stability of the fab by managing complex electrical infrastructure—from the utility substation to the tool-level point of connection—to prevent costly power-related production "excursions.”

System Reliability: Oversee the health of the electrical grid, including Substations, Switchgear, UPS (Uninterruptible Power Supplies), and Emergency Generators

Power Quality: Monitor and mitigate voltage sags (SEMI F47 compliance), harmonics, and transients that can damage sensitive lithography and etch equipment

Capacity Management: Lead projects by performing load flow and short-circuit calculations to integrate new systems into the existing infrastructure

Operational Excellence: Manage large-scale preventative maintenance (PM) schedules and lead Root Cause Analysis (RCA) for any electrical anomalies

Operations & Maintenance: Direct and mentor technical teams in the execution of complex operations and preventative maintenance for electrical systems to ensure peak operational reliability and safety compliance.

Safety Leadership: Ensure all site activities strictly adhere to NFPA 70E (Arc Flash) and NEC standards to maintain a zero-incident workplace

Maintain ESD program for semiconductor cleanroom by conducting routine technical audits, ensuring that all grounding systems are in place a monitored meet ANSI/ESD S20.20 compliance.

This job is for you if you can:

Power Distribution & Reliability:

High/Medium Voltage Management: Oversee the substation and incoming utility feeds down to the tool-level distribution (480V/208V).

Power Quality Monitoring: Use SCADA and PMS (Power Monitoring Systems) to detect "dirty power," such as harmonics or transient surges that could damage sensitive lithography equipment.

Emergency Systems: Maintain and test massive UPS (Uninterruptible Power Supply) banks and diesel generators to ensure the fab can survive a grid failure.

Troubleshoot Electrical Issues:

Ability to troubleshoot electrical aspects of facilities’ systems such as motors, MCCs, breakers, lighting, etc.

Capacity Planning:

Load Calculations: When a new project takes place, calculate project peak and idle electrical loads of new or replacement equipment.

Design Review: Review electrical blueprints for capacity additions, ensuring the correct circuit breakers, cables, and grounding are in place.

Short Circuit & Coordination: Run studies to ensure that if a fault occurs, only the local breaker trips rather than taking down an entire wing of the fab.

Safety & Compliance:

Arc Flash Mitigation: Lead safety studies to determine PPE requirements for electricians and minimize energy discharge risks.

Code Adherence: Ensure all installations meet NEC (National Electrical Code), NFPA 70E, and local semi-specific safety standards (like SEMI S2).

LOTO (Lockout-Tagout): Establish and audit safety procedures for high-voltage maintenance.

Job Requirements:

• B.S. or M.S. in Electrical Engineering from an accredited institution.
• 5 years direct work experience
• Certifications in NFPA 70E and OSHA 10/30 required
• You must be able to perform Short Circuit Analysis, Relay Coordination (ensuring the right breaker trips at the right time), Arc Flash Hazard Analysis.
• Experience with Load Flow and Voltage Drop calculations to ensure tools receive stable power at the Point of Connection (POC).
• Hands-on experience with Medium Voltage (MV) and Low Voltage (LV) equipment including, Substations, Transformers (Dry-type and Oil-filled), Switchgear, Motor
• Control Centers (MCCs), and Variable Frequency Drives (VFDs).
• Deep understanding of Uninterruptible Power Supplies (UPS) and Automatic Transfer Switches (ATS).
• Expert knowledge of the National Electrical Code (NEC).
• Familiarity with SEMI Standards (specifically SEMI S2 for Safety and SEMI F47 for Voltage Sag Immunity).
• AutoCAD: Ability to draft and edit Single Line Diagrams (SLDs) and P&IDs.
• SCADA/BMS: Experience monitoring facility health
• Ability to climb ladders and navigate the Sub-Fab (the utility basement) or the Interstitial (the space above the cleanroom ceiling).
• Willingness to be "On-Call" for power-related emergencies that occur outside of standard business hours.
