IT Network Manager

Lead Global Connectivity - and Protect the Plant Floor

Pittsburgh, PA | Global IT Operations | Domestic & International Travel

Our client is seeking an accomplished IT Network Manager who can lead a global enterprise network while bringing deep, practical expertise in industrial Operational Technology (OT). You’ll own the infrastructure connecting offices, cloud services, data centers, and manufacturing sites - and lead the critical work of securely separating enterprise IT from production networks without compromising uptime or safety.

Why This Opportunity Stands Out

Own a complex, multi-site global network supporting around-the-clock manufacturing.

Shape IT/OT segmentation strategy using the Purdue Model, industrial DMZs, and recognized security frameworks.

Lead a technical team and collaborate directly with plant engineering, cybersecurity, and executive leadership.

What You’ll Do

Lead, mentor, and develop the network team; own priorities, network standards, budgets, and lifecycle planning.

Direct global WAN, LAN, WLAN, SD-WAN/SASE, firewalls, VPN/remote access, and unified communications platforms.

Design resilient, high-availability networks and drive incident response, root-cause analysis, and continuous improvement.

Develop and implement Purdue Model-based IT/OT segmentation, industrial DMZs, and controlled communications between enterprise and plant networks.

Lead OT network assessments, asset inventories, plant segmentation roadmaps, and secure vendor remote-access practices.

Work with cybersecurity and plant teams on OT monitoring, vulnerability management, incident response, and recovery planning.

Oversee network infrastructure for site openings, acquisitions, and integrations; manage carriers and technology partners.

Coordinate plant-safe change windows and support audits, cyber insurance reviews, and security controls.

What You Bring

10+ years of enterprise network engineering/operations experience, including 5+ years in network leadership.

3-5 years of hands-on OT/industrial control system networking in manufacturing or industrial settings.

Demonstrated Purdue Model expertise (Levels 0-5), including IT/OT segmentation and Industrial DMZ design.

Strong knowledge of BGP, OSPF, VLANs, switching, QoS, high availability, SD-WAN/SASE, and next-generation firewalls.

Familiarity with industrial protocols and assets such as EtherNet/IP, Modbus TCP, PROFINET, OPC UA, PLCs, HMIs, and SCADA.

Experience supporting global, multi-site networks and 24/7 manufacturing operations.

Bachelor’s degree in a relevant discipline or equivalent experience; willingness to travel domestically and internationally and support occasional after-hours changes.

Extra Experience We’d Love to See

Fortinet FortiGate/SASE, Cisco/Meraki, Webex Calling, Microsoft Teams Voice, VPN/ZTNA, and network observability.

ISA/IEC 62443, NIST SP 800-82, OT discovery and monitoring platforms such as Claroty, Nozomi, Dragos, or Defender for IoT.

CCNP/CCIE, Fortinet, GICSP/GRID, CISSP, ISA/IEC 62443, or PMP credentials.

The Opportunity

If you understand that plant uptime and safety come first - and you know how to make enterprise networking and industrial cybersecurity work together - this is a chance to lead meaningful change on a global scale.
