About the Security Partners team

We are the trusted security advisors for Tesco Technology. Our purpose is to collaborate seamlessly with the product and engineering stakeholders, leveraging our deep expertise in cyber security to design and implement robust, resilient solutions that protect our business and customers from cyber threats.

We are a dynamic and expanding global team of 15+ experts, serving as the strategic link between the wider security group and software engineering teams that develop cutting-edge services at scale to support the retail business.

Tesco Technology comprises of several technology domains with over 100+ teams, each entrusted with their own security. These teams enjoy significant autonomy, balanced by the responsibility to make customer‑centric decisions and security. Rather than imposing controls through rigid processes and security gates, we empower these engineering teams to innovate by providing security guidance that helps them make informed decisions for Tesco. Encouragingly, these teams are enthusiastic partners in enhancing security, working more efficiently, and integrating security into every aspect of their ways of working. This collaborative approach sets us apart from traditional security teams. We proudly identify ourselves as Security Partners, not security police, emphasizing our role as the "trusted advisors" rather than enforcers.

Partners engage key people in engineering to make security contextual and frictionless. After all, security is a journey and there is no one‑size‑fits‑all.

Join the team and be part of this exciting journey!

The Role

As a Security Partner, you will deeply engage within product areas and influence the way security is delivered by them. You will be supported by experts in the team, nonetheless. To achieve this, you are good at secure design principles, cloud security, secure development practices and patterns, application security, secure pipelines, open‑source security and related. And not to mention, you are versatile to learn anything that comes along your way.

Being the trusted advisor

As enterprise applications become more distributed, adaptive to technological advancements, and run from hybrid infrastructure, teams need to navigate through different complexities and make key security decisions along the way. A trusted security advisor empowers teams to achieve scalable and sustainable security maturity throughout the SDLC process.
