Lead Infrastructure Engineer (Cloud & Compute Security)
Salary: £92,701 - £115,000 per annum
Location: Leeds, Bristol, Edinburgh, Manchester
Hours: Full‑time – 35 hours per week
Working Pattern: Hybrid – at least two days per week (40%) at one of our office sites.
What you’ll be doing
The Chief Security Office (CSO) is a vital part of delivering our vision of putting customers at the heart of everything we do, helping Britain prosper and protecting the Group and customers from security threats. As the Group continues its transformation towards its technology vision of being the UK’s biggest fintech, CSO is evolving into a highly engineering‑led function, focused on delivering security as a platform that supports and accelerates the wider business – increasing automation, improving visibility of risk, and strengthening protection across a complex, multi‑cloud environment.
The Cloud and Compute Security Lab sits at a critical inflection point in that journey and is seeking a dynamic Lead Infrastructure Engineer to join us. We are building a Unified Exposure Management (UEM) platform from the ground up – redefining how security is engineered, delivered, and operated. This is not about maintaining existing controls; it’s about creating a modern, cloud‑native security ecosystem, fully defined through Infrastructure as Code and delivered via CI/CD.
This platform will operate at enterprise scale, monitoring and protecting thousands of workloads across multi‑cloud environments, underpinning critical banking services relied on by millions of customers every day. We are embedding security directly into the engineering lifecycle, establishing contribution and federation models that allow teams to build with us, not around us. Using modern developer tooling, we are creating a platform that scales, adapts, and evolves alongside the organisation, using AI as an extra pair of hands.
The impact is real and immediate – improving resilience, reducing exposure to threats, and strengthening the trust customers place in the bank. This is an opportunity to shape the future of security in a large‑scale fintech – not just operate within it.
Why Join us
We’re a pioneering, fast‑changing business that’s shaping finance as a force for good. If you’re after a role where you can have an impact and do the best work of your career, you’ve found it.
What we’re looking for
- Strong engineering mindset with the ability to build and scale systems, not just operate them
- Experience working in cloud environments (GCP and/or Azure)
- Understanding of compute platforms, including Windows and/or RHEL
- Exposure to Kubernetes and container‑based architectures
- Excellent DevOps engineering skills using Infrastructure as Code (Terraform) and CI/CD pipelines (Harness)
- Experience with Large Language Models and Agentic automation
- Familiarity with modern developer tooling and platform engineering concepts
- Ability to work in ambiguous environments and help define direction
- Strong communication and collaboration skills, with the ability to influence and enable teams across a large organisation
Additional experience that would be great
- Experience across multiple cloud or operating system domains (GCP, Azure, Windows, RHEL)
- Deep expertise in Kubernetes or container security
- Experience building or contributing to platform engineering or security platforms
- Knowledge of exposure management, vulnerability management, or security posture tooling
You don’t need to tick every box. We are more interested in how you think, how you approach problems, and your ability to build and evolve systems in a fast‑moving environment.
Why this role
- Shape a greenfield UEM security platform at true enterprise scale
- Work on systems that directly protect customer‑facing banking services used by millions
- Influence how security is delivered across one of the UK’s largest financial institutions
- Be part of a team redefining what “good” looks like for modern security engineering
