Job description

Overview

Site Reliability Engineer (SRE)
Location: London

I am looking for a number of SREs for a large-scale digital organisation in the middle of a major engineering modernisation journey. This is not a BAU support role, this is a chance to help define what "good" looks like as SRE is brought fully in-house for the first time.

You'll work across high-impact platforms (web/mobile, payments, CRM, operations, cloud) and play a key role in shifting the organisation away from ticket-driven support and towards proactive, automated, AWS-first, engineering-led reliability.

Responsibilities

• Embed SRE principles to improve availability, reliability, performance and incident response
• Modernise legacy support by introducing automation, observability, shift-left practices and CI/CD
• Work across multiple domains (web/mobile, payments, CRM, cloud infrastructure, airline systems)
• Partner with vendors and internal engineering teams; influence technical and financial decisions
• Define and drive SLOs/SLIs, service health metrics and standards
• Troubleshoot, monitor and improve systems using tooling such as Datadog, Splunk etc.
• Contribute to IaC, containerisation and cloud-native adoption (AWS, Terraform, Docker/K8s)
• Mentor and support engineers as SRE ways of working are introduced across the organisation

Experience

• 3-5 years in an SRE or closely related reliability/DevSecOps discipline
• Strong knowledge of SRE practices: monitoring, observability, incident response, automation
• Hands-on with AWS and infrastructure-as-code (Terraform, Ansible or CloudFormation)
• Experience with CI/CD pipelines and container platforms (Docker / Kubernetes)
• Comfortable working with vendors, suppliers and internal product/engineering teams
• Able to communicate clearly and influence engineering culture, not just build solutions
• Exposure to large, complex or vendor-heavy environments is desirable
• Hands-on role leadership through influence, not a line-manager post
