IT/OT Network Architect

From the first morning coffee to the last delivery leaving the warehouse: behind every product that reaches the consumer lies a world of industrial systems, production networks, and operational technologies that must perform without fail, around the clock. As digitalisation continues to accelerate across manufacturing environments, the boundary between IT and OT is shifting fast, and the people who understand both are the ones who will define what comes next.

Tell me more…

Across factory floors and production sites around the world, smart devices, remote connectivity, and evolving cyber threats are pushing IT deeper into the domain of operational technology. Meeting that challenge requires more than technical skill. It requires architecture that is secure by design, resilient under pressure, and forward-thinking enough to support a global operation for years to come. This is where you come in.

What you’ll be working on

We are looking for an experienced and hands-on IT/OT Network Architect to join the IT/OT team, where you design and secure the network infrastructure that underpins industrial control systems, SCADA environments, and production operations worldwide. You will play a central role in a major three-year programme covering more than 40 production sites globally, with a clear mandate: create a robust split between IT and OT networks, improve segmentation, standardise infrastructure across diverse locations, and replace end-of-life hardware. The scope is growing, and so is the ambition.

As an IT/OT Network Architect, you act as the connecting force between engineering, operations, and IT. You don’t just advise. You take ownership, drive implementation, and translate architectural thinking into standards that actually get applied on the factory floor. You navigate a mixed vendor landscape, helping to shape the organisation’s direction between Siemens and Cisco environments. You develop and maintain network standards and documentation, drive modernisation of legacy environments, and ensure the organisation remains both audit-ready and cyber-resilient. You report directly to the Director IT/OT and work closely with stakeholders across IT, OT, Digital, Technology, and Operations throughout the end-to-end supply chain.

What you bring

You bring at least eight years of experience in network engineering, with three to five of those years focused on OT, ICS, or SCADA network architecture in real factory or production environments. You hold a Bachelor’s or Master’s degree in Computer Science, Information Technology, Electrical Engineering, or a closely related field. Experience with Siemens industrial networking is highly valued, Cisco knowledge is equally relevant, and familiarity with both puts you in a strong position given the environments you will be working across.

You are comfortable working with air-gapped or segmented architectures, implementing firewalls and VLANs, and managing the security and compliance demands that come with critical production environments. Familiarity with ISA/IEC 62443 is useful, though hands-on production experience carries more weight than formal certification. A Cisco or Siemens networking certification is a plus. You are able to work independently on architecture, build standards from scratch rather than simply recommending them, and you understand what is at stake when production continuity is on the line. 

What you get in return

Let’s make it concrete. You’ll receive a competitive gross monthly salary between €5,500 and €7,500, depending on your knowledge and experience, based on a full-time schedule. On top of that, you’ll receive a year-end bonus, a solid performance bonus, an 8% holiday allowance, and a solid pension arrangement.

You’ll work in a flexible environment with the freedom to work from home, plenty of vacation days, and the option to buy or sell 40 additional hours. The team comes together on Wednesdays, and the role involves occasional visits to production locations across the network. Beyond the practicalities, you’ll have real room to grow: access to training and coaching, active encouragement of internal mobility, and the autonomy to make a lasting impact on how a global manufacturing organisation integrates its digital and operational future. Apply now and help shape the network infrastructure that keeps operations running for a multi-billion dollar company.
