Experience supporting electrical systems in high-reliability environments such as semiconductor, pharmaceutical, or data center facilities.

Responsibilities

Lead commissioning for facility upgrades, expansions, and new tool installations.
Develop commissioning plans and validation protocols to assess performance, functionality, and compliance with design and operational requirements.
Troubleshoot and resolve technical issues to support timely energization and successful system handoff.
Author, review, and approve electrical project scopes of work and switching/LOTO schedules for outages, tie-ins, and energizations.
Create and maintain SOPs, maintenance procedures, and emergency response plans aligned with industry best practices.
Manage electrical change orders, submittals, and RFIs during project execution.
Provide electrical engineering support across new fab construction, expansions, and tool installations.
Ensure designs comply with NEC, SEMI standards, corporate specifications, and power quality requirements for sensitive equipment.
Validate voltage, current, grounding, and harmonic performance for new tool hook-ups.
Apply load-shedding and restoration strategies to reduce risk during planned outages and unplanned events.
Champion electrical safety during medium-voltage energization and maintenance.
Maintain compliance with NFPA 70E, OSHA, and NFPA 70B standards.
Read single-line drawings and develop and implement LOTO procedures for complex multi-sourced and medium-voltage systems.
Maintain accurate as-built documentation and participate in electrical incident activities.
