Senior Network Engineer

Are you a hands-on network expert who enjoys solving complex connectivity challenges in industrial environments?

We're looking for a Senior IT/OT Network Engineer to join a large-scale digital transformation program, where you'll play a key role in designing, implementing, and validating secure network connectivity across IT and Operational Technology (OT) environments.

This is an opportunity to work on cutting-edge technologies—including SDN, Kubernetes/OpenShift networking, industrial network segmentation, and Wi-Fi 7—while collaborating with multidisciplinary teams to deliver secure, reliable, and production-ready infrastructure.

As a Senior Technical Expert, you'll take ownership of network connectivity across enterprise and industrial environments by:

• Designing and implementing secure IT/OT network connectivity.
• Defining, documenting, and validating network flows between applications, platforms, and infrastructure.
• Configuring and troubleshooting VLANs, routing, trunking, firewall policies, DNS, DHCP, NTP, proxy services, certificates, and TLS.
• Supporting network segmentation, security zoning, and industrial networking requirements.
• Contributing to SDN design, implementation, and troubleshooting activities.
• Supporting Wi-Fi 7 readiness for industrial operations, mobile devices, and shopfloor connectivity.
• Collaborating closely with architecture, infrastructure, cybersecurity, application, and operations teams.
• Troubleshooting complex connectivity issues across wired, wireless, platform, and application layers.
• Producing high-quality technical documentation, network diagrams, flow matrices, and operational runbooks.
• Supporting production readiness, monitoring, knowledge transfer, and operational handover.

We're looking for someone who combines deep technical expertise with a pragmatic, delivery-oriented mindset.

Required Experience

• Extensive experience in enterprise and/or industrial networking.
• Strong knowledge of IT/OT environments and their security and operational constraints.
• Hands-on expertise with routing, switching, VLANs, trunking, firewall flows, and network segmentation.
• Solid understanding of DNS, DHCP, NTP, proxy services, certificates, and TLS.
• Experience troubleshooting complex network connectivity issues.
• Good understanding of Kubernetes or OpenShift networking concepts.
• Experience with or strong exposure to Software-Defined Networking (SDN).
• Ability to collaborate effectively with architecture, cybersecurity, infrastructure, and operations teams.
• Strong documentation skills with experience producing technical designs and operational handover material.

Experience in one or more of the following is highly valued:

• Manufacturing, industrial, warehouse, or critical infrastructure environments.
• Wi-Fi 7 or modern enterprise wireless technologies.
• RF planning, roaming optimization, wireless client connectivity, and coverage validation.
• NAC, IEEE 802.1X, identity management, certificates, or device management solutions.
• OpenShift networking, MetalLB, NMState, or similar technologies.
• Industrial cybersecurity.
• GitOps, Infrastructure as Code, or network automation.

You'll contribute to the successful delivery of a modern industrial network by producing:

• Network flow matrices and connectivity validation.
• Technical network designs and architecture recommendations.
• Firewall, routing, DNS, proxy, certificate, and TLS validation.
• SDN implementation support and troubleshooting.
• Wi-Fi 7 readiness assessments and wireless validation criteria.
• Technical documentation, diagrams, operational runbooks, and handover packages.
• Risk assessments and remediation plans to ensure production readiness.

Who You Are

• You are a senior engineer who enjoys taking ownership and delivering results. You combine strong technical expertise with a structured approach to problem-solving and communicate effectively with technical teams, vendors, and operational stakeholders.
• You work independently, document your work thoroughly, and thrive in environments where reliability, security, and operational excellence are essential.

If you're ready to help shape the next generation of secure industrial connectivity, we'd love to hear from you.
