You’ll focus on maintaining high service availability, improving performance, and optimising how we monitor and respond to incidents. Your expertise in reliability engineering will support continuous improvement, proactively resolve issues before they impact users, and strengthen the overall resilience of our infrastructure. Your key outcomes will be:<ul><li>Developing, Refining, and Automating Monitoring Systems: Design, manage and enhance monitoring, alerting and observability systems - such as Datadog, Prometheus and Grafana - ensuring they deliver meaningful insights and effective alerting. You'll also automate repetitive monitoring tasks to improve efficiency. </li><li>Managing SLOs/SLIs and Improving Incident Response: Define and track SLOs and SLIs for key services, contributing to better reliability insights. You'll also help refine incident response processes, support on-call operations, and improve tooling and communication during incidents. </li><li>Incident Management and Post-Mortem Analysis: Play a key role in resolving complex production incidents, leading or supporting technical response efforts. Following incidents, you’ll conduct blameless post-mortems to uncover root causes and drive lasting improvements. </li><li>Cost Optimisation Implementation: Assess infrastructure usage and apply approved strategies to optimise cloud costs - balancing resource efficiency with performance and reliability. </li><li>Capacity Planning, Performance Tuning &amp; Resilience: Using monitoring and load testing data, you’ll support capacity planning, recommend performance improvements and help implement resilience best practices across systems. </li><li>Collaboration and Knowledge Sharing: Work closely with engineering, QA, security and product teams to embed reliability practices, document key processes and mentor peers to support collective learning and growth. </li><li>Design Review Input:Take part in design reviews, offering guidance on how to improve reliability, scalability and day-to-day operability within system architecture.</li><li>Community of Practice: Actively contribute to your Community of Practice - leading discussions, sharing experiences, mentoring others and helping shape content and capability growth within your area of expertise.</li></ul> You’ll be a successful in this role if you…<ul><li>Have a Software Engineering Background: You have professional experience in programming languages such as Python, Typescript, Go, or Java, and you apply software best practices (CI/CD, unit testing, code reviews) to infrastructure. </li><li>Experienced with the Cloud: You have hands-on experience navigating the complexities of public cloud ecosystems (AWS, GCP, or Azure) and understand the nuances of cloud-native networking and storage. You can demonstrate an understanding of how distributed systems may fail, and how to design for fault tolerance. </li><li>Infrastructure as Code (IaC) Expert: You have advanced experience with Terraform, Pulumi, or Crossplane to manage at-scale infrastructure. </li><li>Data-Driven Mindset: You use metrics and logs to drive engineering decisions. You understand the foundations of SLOs and error budgets. </li><li>Problem Solver: You enjoy complex debugging. You can dive into the Linux kernel or network stack to find the root cause of a performance bottleneck. </li><li>Mentor &amp; Advocate: You are passionate about teaching "The SRE Way" to engineers, helping them take ownership of their services' reliability.</li><li>Efficiency and Cost Engineering Mindset: You treat capacity planning, performance tuning, and cost optimisation as software engineering challenges rather than administrative tasks. You naturally lean toward building "efficiency-as-code"</li></ul> Let’s talk about what’s in it for you:We’ll pay you between £64,070 and £84,569, depending on your specific skills and experience.We keep our pay ranges broad on purpose to give us, and you, flexibility to match your experience to our zero carbon mission.You’ll be eligible for an on-target bonus of 15%.
