Controls Support Specialist - MQTT (Gwinnett County)

Key Accountabilities

Support the deployment of data center control systems, ensuring on-time delivery with minimal defects through effective management of vendors during construction and L1–L5 commissioning phases.
Support final validation of controls, monitoring, and data transport systems, ensuring all functional, performance, cybersecurity, and documentation criteria are complete, accurate, and ready for handover to Operations and customers at PFHO.
Support the implementation of MQTT-based data ingestion and messaging solutions to enable scalable, low-latency telemetry exchange between field devices, control systems, analytics platforms, and enterprise monitoring tools.
Support MQTT topic structures, naming conventions, Quality of Service (QoS) levels, retained message strategies, and payload standards to ensure data consistency, reliability, and operational usability.
Coordinate integration of MQTT brokers with BMS, EPMS, PLCs, SCADA systems, and third-party platforms, ensuring compatibility, redundancy, and secure data exchange across multiple vendors and protocols.
Work with Operations Engineering to support point-to-point verification, MQTT message validation, software logic testing, and graphics validation to ensure operability, data integrity, and quality prior to on-site deployment.
Support QA/QC oversight of controls hardware installation, network infrastructure, MQTT-enabled gateways, vendor proposals, and programming deliverables throughout construction and commissioning.
Support commissioning activities to validate controls logic, alarm thresholds, monitoring configurations, MQTT data flows, broker failover, and end-to-end operability of integrated data center infrastructure systems.
Support Operations, IT, and Cybersecurity teams to diagnose and resolve Loss of Visibility (LOV), Loss of Resilience (LOR), Large Scale Events (LSE), Critical Scale Events (CSE), and other controls- or data-path-related operational incidents within defined Service Level Agreements (SLAs).
Support monitoring, alerting, and performance metrics for MQTT infrastructure, ensuring availability, throughput, message latency, and resilience meet operational and business requirements.
Support continuous improvement initiatives to enhance the efficiency, resilience, and observability of data center controls, MQTT-based telemetry pipelines, and associated operational procedures.
Work with Operations Engineering in the consistent application of standards, documentation quality, and best practices for controls systems, data models, and messaging architectures across projects, vendors, and regions.
