About the role
As we transition to a truly product‑led organisation, SRE becomes the pulse of engineering — the centre of excellence for reliability, monitoring, and observability. You’ll shape our new foundational platform, harden its resilience, and ensure it consistently meets the expectations of our customers. You’ll automate away manual toil, streamline operations, and build the systems and tooling that allow engineering teams to move faster with confidence. Alongside the new platform, you’ll also take ownership of our existing estate — tuning, optimising, and evolving it to modern standards. This is a hands‑on role embedded deeply in the engineering community, operating with a product mindset and delivering value just like any other high‑performing team.
Key responsibilities
- Implementing best practices for monitoring, alerting, and incident response using Datadog and other tools.
- Designing, building, and maintaining cost‑effective, reliable, and scalable AWS infrastructure.
- Collaborating with cross‑functional teams to identify and address performance bottlenecks and reliability issues.
- Conducting post‑incident reviews to analyse root causes and implement preventive measures.
- Automating routine tasks and processes to improve efficiency and reduce manual intervention.
- Participating in an on‑call rotation to respond to system outages and emergencies.
Key outcomes
- Stable, observable platform: Services meet agreed SLAs/SLOs with clear dashboards, playbooks and automated remediation where appropriate.
- Reduced incident impact: Measurable reductions in MTTD/MTTR and clear evidence of prevention from RCA actions.
- Broad adoption of SRE practices: Cross‑team improvements in reliability, testing and operational readiness guided by SRE principles.
Key experience required
- Monitoring and observability best practice including using tools like Datadog, Prometheus, Grafana.
- Expertise in setting up and managing alerts, dashboards, and logging.
- Understanding of networking concepts, security best practices, and performance optimization in AWS.
- Proficiency in AWS services: EKS, EC2, ECS, S3, RDS, VPC, IAM, Route 53, etc.
- Experience with containerization and orchestration tools like Docker and Kubernetes.
- Strong knowledge of Infrastructure as Code (IaC) tools such as Terraform, CDK or CloudFormation.
- Knowledge of scripting and automation using languages like Python, Bash, or PowerShell.
- Experience with CI/CD pipelines for deploying and testing applications in AWS.
Bonus points if you have any additional experience that includes working with AWS ECS, exposure to .NET CDK for infrastructure provisioning, or a good understanding of cloud cost optimisation and FinOps practices.
Company benefits
- 25 days’ holiday + bank holidays
- Option to buy or sell 5 extra annual leave days per year
- Vitality Health Insurance, including private healthcare, virtual GP access and mental‑health support
- Pension with 5% matched contribution
