Network Infrastructure Engineer Ref. 912


This role is available full-time for 37 hours per week, part-time and flexible working patterns. 

World leading software is nothing without world leading infrastructure to run it...

You’ve got the skills to build and support the platforms and infrastructure to allow systems to thrive. Working closely with our software developers and DevOps engineers, you’ll develop new skills and grow your expertise as you build and maintain the platforms and environments to boost their deployments. More importantly, you’ll build your own systems to deliver value to your customers in direct support of the national security mission.

Working as an integral part of a diverse engineering team, you’ll build and maintain the infrastructure to ensure delivery systems run seamlessly. You’ll collaborate with a team of developers, engineers, and stakeholders to ensure that infrastructure is reliable, scalable, and capable of handling the needs of our systems over time. As an experienced network engineer, you will be expected to support apprentice level and junior engineers that you work with.

You’re the person that makes ideas become real. You’ll design, develop, deliver, and support the platforms needed to deploy on, from Cloud and Enterprise builds to physical switches, firewalls, and virtual networks, and we’ll support you as you grow and learn your skills. You’ll work on systems that make a difference to the safety of the UK, and your infrastructure will be critical. You’ll enjoy coming up with creative solutions for global systems that contribute to national security.
