Electrical Systems Subject Matter Expert (SME) – Mission-Critical
Location: Spartanburg, SC
Compensation: $110,000–$160,000 + Bonus
Employment Type: Full-Time | Rotating Shifts (24/7/365 Coverage)

Overview
The Electrical Systems Subject Matter Expert (SME) – Mission-Critical serves as the on-site owner’s technical authority for electrical infrastructure supporting a High-Performance Compute Center (HPCC) and its associated on-site power generation facilities.

This role is part of a five-person Electrical SME team operating on rotating shifts to ensure continuous expert oversight. Electrical SMEs work shoulder-to-shoulder with Critical Infrastructure Operators, Mechanical Systems SMEs, Hybrid Space (Liquid Cooling) SMEs, and Energy Station SMEs to deliver safe, reliable, and procedurally disciplined operations in a live, mission-critical environment.

Electrical SMEs are fully qualified to operate, maintain, and troubleshoot medium- and low-voltage electrical systems, UPS infrastructure, switchgear, and interfaces with generation and power plant systems. The role requires deep technical expertise, calm decision-making in live environments, and strong leadership presence on shift.
