Security isn't always the first thing that comes to mind when you think of BT, but when it comes to keeping everyone safely connected, We Are The Protectors. We deal with thousands of cyber-attacks every day, so that millions of people can safely go about their daily lives and run their businesses. We deliver vital work at scale, with real breadth and impact. We connect for good.
You'll be joining a specialist security team that is a trusted partner to governments worldwide, protecting critical national infrastructure and committed to the safety and security of our nation and global communities. Our mission focused work is innovative, inspiring and technologically challenging in a way that makes every day different and stimulating. We provide the opportunity to work on rare projects, with exciting tools and brilliant people. Everyone has access to unparalleled professional and personal development opportunities and your contribution is always valued.

Why this job matters

As a member of our network engineering team you'll be playing a leading role in a growing team that has full responsibility for the design and implementation of world-class customer focused network solutions, ranging in size from small bespoke solutions to large enterprise scale deployments.

The team is customer focused so you'll have the opportunity to work directly with end customers, understand their requirements and lead the design of solutions that make a significant difference in protecting the society in which we live.

This job role can be based in London or Ipswich. Hybrid (5 days office based). Monday-Friday (37.5 hours per week). You must be able to obtain DV clearance in order to start this role. You will need to have lived in the UK for 10 years+ to obtain this.

What you'll be doing

• Lead the creation of high and low level network designs for complex IP networks.
• Be hands on implementing these solutions, using vendor products such as Cisco.
• Work directly with our customers to understand their requirements and use this to inform your solutions.
• Work with support teams to enable management and the ongoing support of deployed solutions.
• Provide some third line support to deployed solutions.
• Provide support to other members of project teams, setting the technical direction for their own deliveries.

Essential Skills

You'll definitely have

• Have experience of internal and external stakeholder management and engagement.
• Have a certification in a network engineer discipline such as CISCO CCNP Routing and Switching. Though while desirable, practical experience using specific vendors' equipment, such as Cisco is more important.
