Expiry Date: 04/11/26

Due to the sensitive nature of this role, you will be required to undergo DV (Developed Vetting) level Security Clearance (https://www.gov.uk/government/publications/united-kingdom-security-vetting-clearance-levels/national-security-vetting-clearance-levels). 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.

About The Role

This job role can be based in London, Cheltenham, Ipswich or Manchester. Due to security requirements, this role requires you to be located on site during your working hours. Mon-Fri 37.5.

DV Security Clearance is required. Must have lived in UK for 10+ years to obtain clearance.

We intend to expand our team extensively, so we would love to connect with people who have strong IT and engineering skills, and a genuine passion for building, designing, and securing modern technology platforms.

We operate in a software‑defined, automation‑first environment, where everything from infrastructure to security controls is defined programmatically. Our teams work by iterating fast, deploying at pace, and continuously improving through modern engineering practices, moving away from using manual processes or siloed handovers.

We’re particularly interested in individuals who thrive in CI/CD‑driven environments, are comfortable working with Infrastructure-as-Code, and who see automation as the default, not an optimisation. This is a space where engineers have the freedom and responsibility to build, test, secure, and deploy services in an end‑to‑end, highly automated way, with quality and security embedded into products and services from Day One.

If you’re excited by the idea of software‑defined everything, rapid feedback loops, and delivering resilient platforms at scale, we’d love to hear from you. Don’t be put off if you don’t tick all the boxes below; we wouldn’t expect you to …

What You’ll Be Doing

• Own and deliver engineering platform capabilities that enable teams to build, test, secure, and deploy services in a highly-automated, CI/CD-driven environment.
• Design, implement, and evolve CI/CD pipelines, ensuring consistent, reliable, and repeatable delivery processes across multiple teams and services.
• Embed Infrastructure-as-Code (IaC) practices, driving standardisation, scalability, and elimination of manual provisioning and configuration drift.
• Integrate security controls into engineering workflows, ensuring services are secure by design and comply with the highest standards, from initial build through to production.
• Support and enable engineering teams, providing guidance, tooling, and best practices to improve delivery velocity, quality, and resilience.
• Continuously optimise automation, identifying opportunities to remove repetitive manual tasks, reduce cycle times and improve developer experience.
