Everyone who works at Lidl brings something unique to the table - but we also have a whole lot in common. We're curious, collaborative, and ready to make a tangible impact on where we work.

Just like you.

Our IT infrastructure department are looking for a Senior Network Engineer to join their team.

• Model best practices for the wider team, fostering a culture of collaboration and high performance.

What you'll need

• Deep understanding of networking principles, ideally with cross-sectional experience working to CCNP level or above.

• Ability to build relationships with business departments and third-party partners.
• Initiative to 'step up' during crises and 'step in' to support colleagues, working well under pressure.
• Strategic mindset able to look beyond the 'fix' to find the 'solution,' constantly seeking ways to improve the network based on industry developments.
• Experience with Cisco Catalyst Center or Huawei Cloud Portal is desirable
• Experience with Fortinet Firewalls (Fortigate/Fortimanager) would be advantageous
• Experience with SD-WAN technologies.
• Knowledge of VoIP and QoS.
