Senior IT/OT Infrastructure Integration Engineer

Job description

Senior IT/OT Infrastructure Integration Engineer

We are seeking a highly skilled Senior IT/OT Infrastructure Integration Engineer to support the planning, implementation, and execution of infrastructure for a new manufacturing site. This is a hands-on, technical execution role—not a managerial position.

In this capacity, you will serve as a technical integrator, ensuring seamless alignment across infrastructure domains including networking, servers, cybersecurity, automation, validation, and cloud integration. The role spans both manufacturing operations and corporate office environments, requiring deep expertise across IT/OT architectures in regulated settings.

The ideal candidate brings proven, real-world experience delivering infrastructure solutions within GxP-regulated manufacturing environments, with the ability to operate effectively across on-premises, hybrid, and segmented IT/OT ecosystems. This role requires ownership from strategic planning through hands-on implementation, technical support, and ongoing infrastructure evolution.

Key Responsibilities

• Provide technical oversight and quality assurance for IT/OT infrastructure deployment, including networks, servers, storage, backup, disaster recovery, and segmentation
• Review and validate High-Level and Low-Level Designs (HLD/LLD)
• Ensure alignment with Purdue Model segmentation, zero-trust architecture, and regulatory compliance standards
• Coordinate cross-functional dependencies with Automation, MES, LIMS, SCADA, and laboratory systems teams
• Support integration between on-premises infrastructure and enterprise/cloud environments (Azure hybrid)
• Validate configuration standards, system hardening baselines, and network segmentation controls

Technical Skills & Expertise

The ideal candidate will have strong proficiency in:

• IT/OT network architecture and segmentation
• Network security controls and firewall rule management
• Windows Server and Active Directory architecture
• Virtualization technologies (Hyper-V preferred)
• Storage solutions (SAN, NAS, S2D)
• Backup strategies, including immutable storage
• Infrastructure monitoring and integration
• Configuration management, standards, and documentation governance
• Change management processes
• Hands-on technical support
