Job description

Akkodis is seeking an OT Network Engineer to support industrial networking within a large, distributed manufacturing environment. This position will initially focus on hands‑on troubleshooting, incident response, and stabilization of OT network infrastructure, with an emphasis on resolving connectivity issues across plant and manufacturing locations.

The engineer will work primarily with industrial switches, firewalls, network segmentation, and remote‑access technologies such as Ewon, supporting network connectivity on the operational technology side of the IT/OT boundary.

As the environment matures, this individual will also help improve network documentation, identify recurring issues, evaluate site readiness, and support the transition of selected locations toward more proactive monitoring and support.

Salary Range: $135,000-150,000/annually, the rate may be negotiable based on experience, education, geographic location, and other factors.

Responsibilities:

• Troubleshoot OT networking incidents involving industrial switches, firewalls, VLANs, interfaces, routing, ACLs, and remote connectivity.
• Diagnose Ewon remote‑access connectivity and similar industrial remote‑access solutions, including device reachability and network‑path issues.
• Support network connectivity within the OT environment, particularly infrastructure located downstream of the IT/OT firewall boundary.
• Work with IT networking teams when troubleshooting involves technologies such as Cisco ISE, SD‑WAN, firewall policies, routing, access control, or shared network infrastructure.
• Review network diagrams, device inventories, connection methods, and existing site documentation to better understand plant environments.
• Perform initial discovery of network devices and infrastructure at manufacturing locations.
• Identify recurring incidents, configuration concerns, infrastructure gaps, and opportunities to improve supportability.
• Maintain clear documentation of troubleshooting activities, device information, network conditions, escalation paths, and recommended follow‑up.
• Assist with basic Layer 2/Layer 3 documentation, VLAN information, port mapping, network diagrams, and as‑built records.
• Follow established change‑control, maintenance‑window, approval, rollback, and escalation procedures for production environments.
• Help identify sites and devices that may benefit from future proactive network monitoring, lifecycle management, and managed support.

Qualifications:

• Strong network troubleshooting background covering switches, firewalls, VLANs, trunk and access ports, interfaces, routing fundamentals, ACLs, and remote connectivity.
• Previous experience supporting networking infrastructure within manufacturing, industrial, plant, or OT environments.
• Hands‑on Cisco networking experience, particularly switch configuration and troubleshooting.
• Experience troubleshooting Ewon or comparable industrial/vendor remote‑access appliances.
• Ability to determine whether an incident originates within the network infrastructure versus a PLC, SCADA, HMI, control system, or production application.
• Experience working across IT and OT teams to resolve infrastructure issues.
• Comfortable entering environments where documentation, network standards, and technical resources may vary between locations.
• Strong troubleshooting documentation and communication skills.
• Understanding the importance of change control and risk management within operational manufacturing environments.

Preferred Experience

• Cisco Industrial Ethernet / IE-series switches
• Rockwell Automation / Stratix networking environments
• Catalyst Center
• ThousandEyes
• Claroty
• TrustSec / Security Group Tags (SGTs)
• EtherNet/IP
• PTP / CIP Sync
• DLR or REP network resiliency
• QoS and OT network segmentation
• Purdue Model and IT/OT architecture principles

Experience creating or maintaining L2/L3 diagrams, VLAN documentation, port maps, device inventories, and network as‑built documentation is also beneficial.
