Job description

Own the network. Shape it with the people who run it.

You will own the direction for our LAN, Wi-Fi, WAN and network security platforms and play a leading technical role in Polaris, our journey towards a more standardised network landscape. The challenge is not simply to design the right architecture. You must turn it into secure, supportable solutions together with Security, country IT organisations, technical specialists and Atea Managed Services.

This role is for someone who can make sound technical decisions, challenge constructively and create commitment across organisational boundaries.

Your primary responsibilities

You will:

• Own and evolve the technical direction for Atea’s LAN, Wi-Fi, WAN and network security platforms.
• Develop architecture, principles and standards together with key stakeholders and service providers.
• Take a leading technical role in Polaris and translate the target architecture into practical network solutions across Atea offices.
• Turn business and site requirements into pragmatic solutions that balance security, standardisation, operability and cost.
• Set direction for migrations and complex network changes, while providing deeper expertise when escalations require it.
• Drive lifecycle and vulnerability management, documentation, licensing and continuous improvement of the network platform.

About you

You combine strong enterprise networking expertise with the judgement needed to take technical ownership across a complex organisation.

We expect you to bring:

• Solid practical experience with enterprise LAN, Wi-Fi and WAN or SD-WAN, combined with a strong understanding of network architecture.
• Experience with areas such as segmentation, access control, firewalls, network security or NAC.
• The ability to create and assess both high‑level and low‑level solution designs and connect architecture with operational reality.
• Experience working across stakeholders and with managed service providers, where success depends on clear expectations, constructive challenge and follow‑through.
• Experience from large, multi‑site environments, including lifecycle or vulnerability management.
• Ideally, practical experience with Cisco enterprise networking. Our environment includes Cisco SD‑WAN, Software‑Defined Access, Catalyst Center, ISE and Secure Access. Relevant certifications are an advantage, but practical experience matters more.

You are proficient in English, including technical IT terminology. Proficiency in Danish, Norwegian, or Swedish is considered an advantage.

This is

This is not a pure operations role, nor is it a role where you can succeed by producing architecture and handing it over to others. You need to be comfortable owning the technical direction while working through multiple stakeholders and service providers to turn decisions into practical outcomes.

Why choose Atea?

This is an opportunity to influence what Atea’s network becomes, rather than simply maintain what already exists.

Through Polaris, you will help shape a common network architecture across Atea offices and work closely with experienced colleagues in networking, security, cloud, professional services and managed services.

The role gives you significant technical ownership, but also a real challenge: balancing security, standardisation, operational needs and cost while bringing different stakeholders along. If you enjoy making architecture work in the real world and want visible influence on a large, multi‑site network landscape, this is where the role stands out.
