ABOUT THE ROLE

Join the Information Security Engineering team at John Lewis Partnership to help build a secure future for an iconic brand. We work to protect our customers, Partners, and business against an ever-evolving cyber threat landscape.

The John Lewis Partnership’s Information Security strategy is bold and ambitious. We provide a collection of security services, delivered via people, processes and technology. Working collaboratively, these services ensure that customers can shop with us efficiently, safely and securely, every single day.

Our Threat Defence team is at the forefront of our cyber resilience, proactively monitoring threats, identifying vulnerabilities, and engineering robust security defences.

This is a great opportunity to directly shape our security posture, getting hands-on with next-generation cyber security tools. You'll thrive in an agile, supportive, and highly collaborative team where innovation isn't just encouraged, it's expected.
