Architecte Senior Réseaux et Infrastructure OT/IT (H/F)

Consulting role for customer assignments in Denmark.

As a Senior OT/IT Network & Infrastructure Architect at Opoura, you will work as a consultant in customer environments where experienced technical judgment is needed. You will typically take responsibility for complex OT/IT infrastructure challenges that span architecture, implementation, and transition into reliable operations.

When a suitable assignment is confirmed, you will join Opoura in a permanent position and work primarily with the customer, usually on assignments lasting 6-12 months or longer.

We are currently seeing increasing demand for this level of expertise and already have active customer needs and concrete opportunities where relevant Architects may come into consideration. We are therefore building a talent pool of experienced profiles so we can move quickly when there is a strong match between a customer need and your background.

This is not a vacancy tied to one specific customer or immediate start date. The opportunity depends on the right assignment, but when the match is there, the process can move quickly.

Your role

You will join OT Solutions within Opoura's Digital Services Business Unit and work closely with customer specialists, operations teams, suppliers, engineers, and other technical stakeholders.

Most assignments will place you directly within an existing customer environment. That means understanding the infrastructure already in place, identifying what needs to change, and helping the customer make technical decisions that work not only on paper, but also in implementation and day-to-day operations.

The role is deliberately broad enough for you to work across architecture and technical detail. You might be defining an infrastructure design, reviewing network segmentation, resolving gaps before operational handover, or helping improve the way recurring infrastructure activities are standardized and automated.

You will report to Kent Weiling, OT Solutions Manager, who will remain your direct manager and point of contact for sparring and alignment.

Our customers within this area are currently concentrated in Greater Copenhagen, the Triangle Region and Central Jutland. You should expect to work at the customer site around 2-3 days per week, depending on the assignment, combined with remote work and occasional time at Opoura's headquarters in Silkeborg. International travel is not expected.

Your main responsibilities

Depending on the customer assignment, you will:

• Own OT/IT network and infrastructure solutions from technical assessment and architecture through implementation and operational handover.
• Design, assess, and troubleshoot industrial networks, including routing, switching, VLANs, segmentation, firewalls, VPNs, remote access, and site connectivity.
• Drive technical site intake and operational readiness, including documentation, access, monitoring, ownership, maintainability, and closure of identified gaps.
• Contribute senior expertise during implementation, commissioning, migrations, and complex root-cause analysis together with customer teams, suppliers, and operations.
• Improve lifecycle management, standardization, and automation through reusable designs, Infrastructure as Code, source-of-truth data, templates, and automated validation where relevant.

To be successful in this position, you

• Understand complex existing environments quickly and distinguish between what needs to change and what can remain.
• Move comfortably between architecture-level decisions and configuration-level detail.
• Build credibility with customers through clear reasoning, dependable delivery, and direct technical communication.
• Challenge assumptions constructively and turn unclear technical issues into practical decisions and next steps.
• Work independently without losing alignment with the wider customer organization or Opoura.
• Apply standards where they add value while remaining pragmatic when the environment calls for a different approach.

Your background

This is a role for an experienced Architect who can contribute at senior level from the outset. We are not looking for one narrowly defined CV, and you do not need equal depth across every technology area.

We expect that you bring several of the following:

• Significant experience within network and infrastructure engineering or architecture, combined with substantial exposure to OT, SCADA, industrial systems, or other operational environments.
• Experience taking infrastructure from assessment and design through implementation, handover, or operations.
• Strong industrial networking knowledge across areas such as routing, switching, segmentation, firewalls, VPNs, remote connectivity, and multi-site environments.
• Experience with infrastructure platforms and core services such as Windows Server, Linux, Active Directory, DNS, DHCP, PKI, virtualization, storage, backup, and recovery.
• A practical understanding of secure and resilient OT infrastructure, including controlled access, hardening, maintainability, and lifecycle considerations.
• Experience with automation or Infrastructure as Code using technologies such as Python, PowerShell, Terraform, Ansible, Git-based CI/CD, APIs, or source-of-truth platforms is an advantage.

Professional fluency in English is required. Danish or another Scandinavian language is an advantage, but not a requirement.

Experience from wind, renewable energy, utilities, manufacturing, process industries, transport, system integration, or other critical infrastructure can all be relevant. Experience with technical site intake and transition to operations is particularly valuable.

What we offer

For an experienced Architect, the value of this role is the combination of technical depth, variation, and continuity.

You can expect:

• Longer assignments that give you time to understand the environment, shape the solution, and see the outcome of your decisions.
• Customer situations where you are brought in for your experience and judgment, not simply to execute a predefined task list.
• Exposure to different OT and infrastructure environments over time, while maintaining the continuity of permanent employment with Opoura.
• The opportunity to work across architecture and practical delivery rather than being confined to one narrow layer of the technology stack.
• Scope to improve standards, automation, lifecycle practices, and delivery methods where your experience can make the work more robust and repeatable.
• Flexibility between customer-site work, remote work, and occasional time with Opoura in Silkeborg, within the needs of each assignment.
