What You Will Do

• Design and implement PLC-based control systems for cooling distribution equipment, including pump and valve control, thermal regulation, and safety interlocks.

• Develop and debug control logic for fault detection, failover mechanisms, and system recovery in case of pump or component failure.

• Create HMI interfaces for local and remote monitoring, enabling intuitive control and diagnostics of cooling system operations.

• Define electrical interface specifications and collaborate with electrical engineering teams on panel design and layout.

• Integrate control systems with Building Management Systems (BMS) and Data Center Infrastructure Management (DCIM) platforms for centralized monitoring and control.

• Establish and configure industrial communication protocols (Modbus, BACnet, Ethernet/IP) for seamless interoperability across systems.

• Develop control algorithms for energy optimization, load balancing, and predictive maintenance.

• Produce comprehensive documentation including I/O lists, logic diagrams, commissioning procedures, and test plans.

• Support field commissioning and troubleshoot control system issues during installation and operation.

• Collaborate with cybersecurity teams to ensure control system resilience and compliance with data center security standards.

• Implement automated testing and validation procedures to ensure control system reliability and performance.
