A solid understanding of platform and reliability engineering approaches, including observability, performance optimisation, analytics and security best practices, underpins the role. You will also facilitate collaboration between teams, mentor more junior engineers on coding standards and troubleshooting, and help build a culture of continuous improvement.

• Experience with AWS products such as Lambdas and DynamoDB, and comfort working in Azure and Azure DevOps environments

You do not need to tick every box on this list, and the employer would rather you applied and kept learning than held back.

This role is hybrid: two days a week in the London office and roughly once a month at the Fleet office.
