Principal Facilities Electrical Engineer (High Voltage)

We are seeking an Electrical Engineer with specialized expertise in commissioning, project execution and operational readiness within a high-demand semiconductor manufacturing environment. This critical role ensures the seamless integration of new and upgraded electrical systems - from design validation through energization - while maintaining uninterrupted fabrication operations. The ideal candidate will have extensive experience with medium-voltage electrical systems up to 12,000 V and a proven track record of executing complex projects safely and efficiently.

Key Responsibilities:

• Commissioning & Startup Leadership:
• Lead commissioning for facility upgrades, expansions and new tool installations.
• Develop commissioning plans and validation protocols for performance, functionality and compliance with design and operational requirements.
• Troubleshoot and resolve technical issues to ensure timely energization and successful system handoff.

• Project Execution & Documentation:
• Author, review and approve electrical project scopes of work (SOWs) 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.

• Facility Upgrades & Tool Installation:
• Provide electrical engineering support across the project lifecycle, including 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.

• Power System Reliability & Safety:

• Apply load-shedding and restoration strategies to minimize risk during planned outages and unplanned events.

• Champion electrical safety, particularly during medium-voltage (up to 12 kV) energization and maintenance.

• Maintain compliance with NFPA 70E, OSHA and NFPA 70B standards.

• Ability to read single-line drawings.

• Develop and implement robust LOTO procedures for complex multi-sourced and medium-voltage systems.

• Maintain accurate as-built documentation and participate in electrical incident.

• Preferred Bachelor’s degree in Electrical Engineering or equivalent

• 5-10 years of electrical engineering experience, construction support, and operational troubleshooting.

• Proficient in power distribution systems, motor control centers (MCCs), VFDs and backup/emergency power systems.

• Experience with low and medium-voltage systems up to 12,000 V is required.

• Good knowledge of electrical codes and standards, including NEC, NFPA 70E, IEEE, and NETA.

• Skilled in Revit and CAD drafting platforms (e.g. AutoCAD). Preferred Qualifications

• BS in Electrical Engineering with a focus on power systems or controls. 

• Control systems troubleshooting and commissioning experience.

• Experience performing power systems studies, including protective device coordination, arc flash analysis, short circuit calculations and cable schedules.

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

• This role will work on site in Roseville, CA.

• This position works Monday- Friday, overtime as required

• Indefinite US work authorized individuals only.  Future sponsorship for work authorization unavailable.
