Job description

A global medical device manufacturer is seeking a Staff Controls OT Engineer to serve as the technical bridge between Manufacturing, Controls Engineering, Corporate IT, and Cybersecurity. This is a hands-on manufacturing network role focused on designing and maintaining plant-floor infrastructure, connecting automated production cells, and implementing corporate cybersecurity requirements.

The ideal candidate is a manufacturing-focused network engineer who understands how PLCs, cameras, switches, and other devices communicate inside an automated production environment.

What You'll Do

• Own the design, maintenance, and continuous improvement of plant-floor network infrastructure.
• Design VLANs, IP addressing schemes, network segmentation, and secure remote-access processes.
• Support network connections between PLCs, cameras, HMIs, robots, controls hardware, and enterprise systems.
• Manage the network architecture connecting automation-cell switches to plant IDFs and MDFs.
• Define processes for switch replacement, password ownership, access control, and network maintenance.
• Implement cybersecurity requirements in partnership with the corporate cybersecurity team.
• Deploy and maintain approved tools such as CrowdStrike across manufacturing equipment.
• Ensure manufacturing devices have the correct software, licensing, connectivity, and security configuration.
• Review equipment network and security requirements during vendor selection, FAT, and SAT.
• Support OT incident response, disaster recovery, asset inventory, and business continuity.
• Develop standards and processes that can be implemented across global manufacturing sites.
• Travel to manufacturing locations, including international sites, to support teams and equipment.

What You'll Bring

• 6 to 10 or more years of network engineering, industrial networking, OT infrastructure, or related experience.
• Hands-on experience supporting networks within manufacturing or industrial environments.
• Strong knowledge of network design, switches, VLANs, IP addressing, segmentation, firewalls, and remote access.
• Working understanding of PLCs and controls-system communications.
• Ability to troubleshoot connectivity between PLCs, cameras, switches, and other automation-cell devices.
• Experience collaborating with Corporate IT, cybersecurity, controls teams, and equipment vendors.
• Familiarity with industrial protocols such as EtherNet/IP, Modbus TCP, or OPC UA.
• Knowledge of Cisco IE, Allen-Bradley Stratix, Moxa, or similar industrial networking products.
• Bachelor's degree in Electrical Engineering, Computer Science, Computer Engineering, Cybersecurity, or a related field.
• Strong teamwork, communication, documentation, and project-management skills.

Why This Role

• Serve as the critical link between Manufacturing and Corporate IT.
• Own plant-floor network design and maintenance rather than serving only as an advisor.
• Work directly with automated production cells and industrial controls infrastructure.
• Implement practical cybersecurity protections in a regulated manufacturing environment.
• Establish network processes and standards across global sites.
