Job summary

Intersect is seeking a SCADA Engineer to support real-time control systems powering our utility-scale clean energy fleet. You’ll maintain Ignition SCADA HMIs, alarms, and control workflows while ensuring high availability and OT network security in collaboration with Control Room, trading, engineering, and field operations.

You’ll work on ISO telemetry, field hardware integration, and IOC build-out, handling IEC 61850, ICCP, DNP3, Modbus, MQTT, and related protocols in ERCOT markets.

Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Systems Engineering, or equivalent technical discipline.
• 3–5+ years of hands-on SCADA and controls experience supporting control room operations for utility-scale solar PV, BESS, or high-voltage substation assets.
• Demonstrated expertise developing and maintaining Inductive Automation Ignition SCADA platforms and HMI interfaces.
• Proven proficiency with industrial communications protocols and ISO telemetry including ICCP, DNP3, Modbus, MQTT (Sparkplug B), and IEC 61850 in ERCOT, CAISO, or PJM markets.
• Direct experience programming and troubleshooting SEL RTACs, PLCs, protection relays, and Power Plant Controllers.
• Experience supporting or maintaining a Canary Labs historian (or comparable industrial time-series historian) in a production SCADA environment.
• Familiarity with Palo Alto/Fortinet firewalls and NERC CIP compliance requirements.

Responsibilities

• Provide Hands-On SCADA Support and Maintenance
• Maintain and troubleshoot Ignition SCADA HMIs, alarm modules, and control workflows for utility-scale solar PV and BESS facilities, including hands-on control parameter adjustments and logic fixes
• Diagnose and resolve plant communications and control system issues under time-sensitive conditions
• Support and extend the Canary Labs high-speed time-series historian for real-time archiving, performance trending, and operational analytics
• Ensure high system availability and rapid root-cause analysis, providing as-needed escalation support for forced outages, trips, and critical telemetry loss
• Support IOC Build-Out and Ongoing Operations
• Support the ongoing build-out of Intersect's Integrated Operations Center (IOC) from an operational standpoint, applying and helping maintain established standards for data mapping, alarm management, HMI configuration, and version control
• Support ISO telemetry and field hardware integration efforts across ERCOT, including protocols such as ICCP, DNP3, Modbus, and MQTT (Sparkplug B)
• Assist in programming and troubleshooting SEL RTACs, PLCs, protection relays, and Power Plant Controllers
• Support FAT, SAT, and commissioning activities, including telemetry validation, for new sites entering real-time operations
• Work With and Support OT Security and Compliance
• Work with OT network segmentation practices and support firewall-related tasks (Palo Alto/Fortinet) as needed
• Maintain awareness of NERC CIP compliance standards and access control policies in day-to-day work
• Support Operational Excellence and Fleet Standards
• Apply standardized practices for data management, HMI configuration, and alarm handling across operational facilities
• Partner cross-functionally to optimize system visibility and response times
• Contribute to ongoing improvements in reliability and performance across the fleet
