About The Security & Capability Team

Our team is responsible for providing and maintaining tools used by Tesco in order to monitor and secure our systems, while also helping our colleagues globally.

We maintain global hybrid instances of our chosen tools for SIEM, Application Performance Monitoring, Log Monitoring, Backlog Management, Identity Access Management, Service Desk, self-help portals for colleagues and incident communications. In addition to the challenges delivering this capability brings, we're also the team responsible for the security operations centre and our security architecture, working across Tesco globally to secure our systems and data! Our Technology Risk & Compliance team works tirelessly to further develop a risk aware culture and drive audit and regulatory improvements across the technology team in all Tesco countries.

We aim to provide colleagues with a great experience by providing world class tooling, processes and advice. We believe in solutions that are either self-service or invisible to the end user - that's not always easy to achieve, but it's what we strive for. With over 460,000 colleagues globally, this is an opportunity to make your mark.
