• Work with databases supporting controls, monitoring, alarming, reporting, analytics, and operational data workflows.
• Partner with site operations teams to troubleshoot controls‑related events, perform root cause analysis, and support corrective actions for building automation, PLC, SCADA, and EPMS‑related systems.
• Support integration and validation of power quality meters, including devices configured for continuous waveform monitoring, event capture, power quality analysis, and electrical system diagnostics.
• Collaborate with commissioning agents, contractors, vendors, and internal engineering teams to verify system performance, sequence execution, alarm behavior, trend collection, data integrity, and turnover documentation.
• Support site operations by reviewing control logic, plant staging, pumping sequences, valve control, temperature control, differential pressure strategies, and system performance.
• Assist with operational readiness, site acceptance testing, integrated systems testing, and turnover of controls and monitoring systems from construction to operations.
• Ensure proper metering, trending, and data collection to support operational reporting, energy efficiency, reliability tracking, and long‑term optimization.
• Partner with IT, cybersecurity, network, and monitoring teams to support secure and reliable connectivity for OT systems, PLCs, SCADA servers, MQTT brokers, databases, and field devices.
• Provide technical support and training to site personnel on controls system functionality, alarm response, data interpretation, and troubleshooting procedures.
