Due to the sensitive nature of this role, you will be required to undergo DV (Developed Vetting) level Security Clearance (). An allowance of £5k per annum may be payable monthly while you hold this DV and continue to work in a role that requires that level of security clearance. The terms of this allowance will be made available if you are successful in being recruited into this role.

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.

We are engineers who build, automate, and sustain the environments and enabling services that deliver mission‑critical outcomes.

Today, we work primarily (not exclusively) with on‑premises technology stacks, however our focus is not the racked hardware or deployment cycles of vSphere or SAN storage, we are engineers consuming these technologies at the API and automation layers. We have projects using automation to deploy virtual machines and enact detailed and complex guest OS configurations across enterprise Windows and Linux environments.

Our job isn’t to follow vendor blueprints or push a single technology stack; we aim to solve complex technical problems cleanly and reliably. We have broad autonomy to pick the right tool for the job, whether that is deploying cutting‑edge open‑source projects, engineering enterprise Windows and Linux systems, or writing custom integrations to tie disparate platforms together.

Whether your background is rooted in core Windows administration, Linux, or network engineering, what matters is your ability to break down problems, automate repetitive work, and build systems that last.

This role requires eligibility for UK Developed Vetting (DV) clearance. As a result, applicants must typically be sole British citizens and have lived in the UK continuously for the previous 10 years, subject to UK Government vetting requirements.
