Job Summary The Senior Controls Engineer, OT Fleet Management, is a regional technical leader responsible for advancing the security, reliability, supportability, and lifecycle health of operational technology systems across the data center fleet. The role combines deep industrial controls expertise with strong OT network, server, virtualization, database, and cybersecurity knowledge to lead Threat Vulnerability Management (TVM) execution for building management, supervisory control, power monitoring, and related OT platforms. This engineer will translate identified vulnerabilities and technology risks into executable remediation plans, coordinate vendors and contractors performing upgrades or corrective work, validate technical outcomes, and maintain clear evidence through closure. The role also strengthens regional capability by coaching local Controls Engineers, developing practical training, and establishing repeatable methods that reduce long-term dependence on external resources. The successful candidate is equally comfortable troubleshooting a programmable logic controller, reviewing an OT network architecture, assessing a Windows or SQL Server dependency, leading a vendor remediation call, and explaining risk and progress to technical and operational stakeholders. Responsibilities TVM and OT Lifecycle Management Own regional execution of the Controls Engineering TVM program, from technical assessment and prioritization through remediation, validation, evidence capture, and closureAssess vulnerabilities, obsolete components, unsupported operating systems, database dependencies, network exposures, and platform lifecycle risks affecting BMS, SCADA, PLC, historian, gateway, and related OT environmentsDevelop practical remediation strategies that balance cybersecurity risk reduction, operational continuity, platform supportability, and change risk in live critical facilitiesMaintain regional remediation roadmaps, risk registers, dependencies, technical decisions, and status reporting; escalate blockers with clear options and recommended actionsSupport platform modernization, patching, upgrade, migration, and replacement planning, including rollback, validation, and operational readiness requirements Operations Controls Engineering Provide advanced technical support for industrial controls and supervisory platformsTroubleshoot end-to-end controls issues across field devices, controllers, I/O, communications, gateways, application servers, databases, graphics, alarms, trends, and integrationsReview controls architectures, sequences of operation, control narratives, P&IDs, electrical one-lines, network diagrams, points lists, alarm configurations, and system documentationApply strong knowledge of industrial protocols such as BACnet, Modbus, OPC UA/DA, EtherNet/IP, and vendor-specific communications to diagnose and remediate system issuesPartner with engineering and operations teams to ensure remediated systems continue to meet monitoring, alarming, control, redundancy, and data-quality requirements OT Infrastructure and Cybersecurity Provide hands-on technical leadership for OT networks and server environments, including virtualization, domain and workgroup services, backup and recovery, remote access, time synchronization, certificates, and endpoint protectionReview network segmentation, firewall rules, switch configurations, routing, addressing, redundancy, access controls, service accounts, and data flows supporting controls systemsCoordinate with IT, cybersecurity, network, infrastructure, and operational stakeholders to resolve cross-domain dependencies while preserving appropriate ownership boundaries and site availabilityApply secure-by-design and defense-in-depth principles to OT changes, including least privilege, controlled remote access, asset inventory, configuration management, patch governance, and recovery preparednessLead technical validation after remediation, confirming system functionality, communications, alarming, trending, integrations, resilience, and documented rollback or recovery capability Vendor, Contractor, and Program Execution Define scopes of work, technical requirements, acceptance criteria, test plans, and required closeout evidence for vendors, system integrators, and contractorsProvide technical direction and oversight during remediation activities;
