Key responsibilities include:
• Act as the primary on-site IT/OT contact for Manufacturing, QC, Engineering and Automation, Quality, vendors, and shared IT teams.
• Lead evidence-based troubleshooting for manufacturing and laboratory systems, isolate issues and system dependencies, document findings, engage the appropriate resolver teams, and drive issues through testing and resolution.
• Gather business and vendor requirements, identify specification gaps, and translate them into technical requirements for servers, storage, virtualization, networks, VLANs, firewall flows, identity and access, backup, monitoring, and recovery.
• Coordinate delivery across shared IT services, business functional areas, and vendors.
• Support regulated system implementations, technical assessments, architecture and security reviews, validation activities, operational turnover, and post-go-live stabilization.
• Create and maintain system inventories, data-flow diagrams, architecture diagrams, firewall and interface requirements, support runbooks, knowledge articles, and CMDB records.
• Support segmentation and security-zoning initiatives using ISA-95 and Purdue-model principles, including controlled communication between enterprise, manufacturing, supervisory, control, and device layers.
• Support secure industrial data connectivity between PLCs, HMIs, SCADA, historians, MES, laboratory systems, gateways, and enterprise platforms, including OPC UA, tags and namespaces, certificates and endpoint trust, authentication, secure cross-zone data flows, testing, and monitoring.
• Support regulated laboratory environments, including chromatography systems, acquisition workstations, application servers, instrument connectivity, directory integration, role-based access, and vendor coordination.
• Coordinate patching, firmware updates, infrastructure lifecycle work, and planned outages using risk-based planning, validation requirements, testing, and stakeholder approval.
• Maintain disciplined ServiceNow, change-control, and GxP documentation practices.
• Monitor operational risks including storage capacity, backup status, retention, recovery readiness, system availability, and clarity of support ownership.

REQUIREMENTS:
• Minimum five years of relevant experience in IT infrastructure or IT/OT support in a regulated manufacturing or laboratory environment.
• College diploma or university degree in Computer Science, Information Technology, Engineering, or a related field. Equivalent education, training, and relevant experience may be considered.
• Demonstrated ability to troubleshoot across device, operating-system, application, network, infrastructure, security, and vendor-support boundaries when documentation or direct administrative access is limited, including defining and testing sources, destinations, ports, protocols, authentication, certificates, and system dependencies.
• Practical knowledge of Windows administration, Active Directory, VMware, networking, VLANs, DNS, DHCP, firewall requirements, backup, storage, monitoring, and recovery.
• Experience gathering business and vendor requirements and converting them into diagrams, infrastructure specifications, actionable technical requests, test plans, and support documentation.
• Practical understanding of ISA-95 or Purdue-model concepts, segmentation, DMZs, security zones, trust boundaries, and controlled communication between OT and enterprise systems.
• Experience supporting or coordinating laboratory and manufacturing systems such as LIMS, chromatography systems, SCADA, HMI, historians, MES, and instrument-connectivity platforms, including working knowledge of OPC UA, server and gateway architectures, tags and namespaces, certificates, endpoint trust, secure data flows, testing, and monitoring.
• Working knowledge of GxP and GMP expectations, validation support, audit readiness, data integrity, documentation discipline, and risk-based change management.
• Strong documentation skills, including incident notes, technical requirements, diagrams, runbooks, knowledge articles, and asset or CMDB records.
• Strong planning, prioritization, stakeholder communication, ownership, and shared-services coordination skills, with the ability to manage concurrent operational and project work based on business, operational, and compliance risk.
• Ability to work on site at the Whitby facility and support planned maintenance, implementation, testing, and critical operational activities as required.
• Relevant Microsoft, VMware, networking, cybersecurity, automation, or IT service-management certifications are considered an asset.
