OT Network Engineer

Details

You keep the network backbone behind Eneco's wind farms, solar parks, batteries and heat installations running around the clock. You work end-to-end: from the first design conversation through commissioning to live troubleshooting. Your work directly supports the assets that drive the energy transition, in a mission-critical landscape where reliability comes first.

Why choose Eneco?

At Eneco we work towards one clear goal: being fully climate-neutral, for ourselves and our customers, by 2035. Reaching that goal depends on production assets that stay securely connected and available every hour of the day. Within our Tech organization, the Operational Technology (OT) domain keeps the network behind those assets running. Wind, solar, battery storage and heat all rely on it. As OT Network Engineer you make sure that foundation is secure, resilient and ready for what comes next, working in a team where availability and safety are taken seriously and people support each other to get it right.

Responsibilities

• Design, build and operate the OT networks behind production assets like wind farms, solar parks, battery energy storage systems (BESS) and heat installations.
• Handle both new sites (greenfield) and existing environments (brownfield), from design through implementation and commissioning.
• Set up secure, resilient site connectivity, including network segmentation and clear separation between IT and OT.
• Troubleshoot live network and connectivity issues, taking ownership from first analysis to full resolution.
• Work across SCADA and PLC systems and OT network protocols such as IEC 60870-5-104, OPC-UA and Modbus, applying security standards like IEC 62443 and ISO 27001.
• Own incidents from a network perspective: analysis, resolution, escalation and clear communication until the issue is fully solved.
• Drive structural improvements, standards and lifecycle management of the OT network.

Requirements

• At least 5 years of experience in a similar network engineering role.
• A bachelor's degree in computer engineering or a related field.
• Solid expertise in network segmentation, routing, switching, firewalls and VPN technologies.
• A good understanding of security concepts and frameworks like ISO 27001 and IEC 62443.
• Hands-on experience with OT environments, including SCADA and PLC systems, and familiarity with OT protocols such as IEC 60870-5-104, OPC-UA and Modbus.
• Strong communication skills and the ability to work well with internal teams, vendors and integrators.
• A willingness to join the 24/7 on-call rotation.
• A base in the Netherlands and fluent English.
• Experience in renewable energy is a welcome plus.
