Engineer/Analyst – Data Historian System Administrator

Monitoring & Diagnostics (M&D) Job Summary This position will function as part of the Southern Power Monitoring & Diagnostics (M&D) Center, which provides remote monitoring and diagnostic support to the SPC fleet of gas, solar, wind, and energy storage assets. The Data Historian System Administrator serves as the SPC Subject Matter Expert (SME) for the operational data historian platforms the M&D and Operations organizations depend on — AVEVA PI (approximately 85%) and AspenTech IP.21 (approximately 15%). The role owns day-to-day administration, health, security, performance, and expansion of these environments, including PI Data Archive and Asset Framework (AF) server management, interface and connector configuration, tag and AF governance, site onboarding, upgrades and migrations, disaster recovery, and end-user support.
