The OT Infrastructure Engineer is responsible for the design, deployment, and operational integrity of Operational Technology (OT) systems across Keel Infrastructure’s global portfolio of data centers and energy infrastructure. Reporting to the Director of Global Network Infrastructure, this is a hands‑on engineering role requiring deep expertise across industrial control systems, facility automation, and OT networking – with direct accountability for the reliability and security of the OT infrastructure underpinning data center operations worldwide.

The OT Infrastructure Engineer owns the full lifecycle of the OT systems – from architecture and engineering design through commissioning, steady‑state operations, and lifecycle refresh – across SCADA platforms, distributed control systems (DCS), programmable logic controllers (PLC/RTU), building management systems (BMS), power monitoring, and facility automation infrastructure. This role works in close coordination with the Infrastructure Operations Center (IOC), IT infrastructure teams, and data center facilities to ensure full OT operational visibility and robust IT/OT integration across all sites.

• Own the architecture, design, and full lifecycle of OT systems across all Keel’s data center and energy infrastructure sites – including SCADA platforms, DCS, PLC/RTU controllers, HMI systems, historian platforms, BMS, energy management systems (EMS), and power monitoring infrastructure.
• Design, configure, and validate control logic, I/O mappings, and communication architectures for data center facility automation systems – including analog/digital I/O, interlock logic, alarm management frameworks, and setpoint management across multi‑site deployments.
• Manage OT communication protocol stacks and integration layers – including Modbus, TCP/RTU, DNP3, BACnet/IP, PROFINET, IEC 61850, OPC-UA, and MQTT – ensuring reliable, well‑documented data flows between field devices, controllers, and supervisory layers.
• Engineer, configure, and commission OT networking infrastructure – including industrial Ethernet switches (managed L2/L3), ring redundancy topologies (HSR/PRP/RSTP), serial communication converters, and OT DMZ architecture at the IT/OT boundary.
• Perform capacity planning and performance analysis for OT infrastructure – monitoring historian tag counts, controller CPU/memory utilization, polling cycle times, and OT network bandwidth to ensure headroom is maintained ahead of data center expansion.
• Maintain OT configuration management standards – including version‑controlled PLC/SCADA project backups, firmware revision logs, change history records, and golden‑image management for all programmable field devices.
• Manage the full OT asset lifecycle – from procurement and factory acceptance testing (FAT) through site acceptance testing (SAT), commissioning, and end‑of‑life decommission – maintain an accurate OT asset register and CMDB.
