5. Guide the team in building automated, self-healing systems.
6. Own and evolve incident response processes, including on-call practices and post-mortem culture.
7. Mentor engineers on reliability, operational readiness, and scalable infrastructure best practices.
8. Drive Infrastructure as Code (IaC) initiatives using Terraform, Kubernetes, CloudFormation, and GitOps.
9. Collaborate with security, DevOps, and software teams to ensure compliance and operational excellence.
10. Evaluate and introduce tools and practices to improve platform performance and reliability.

Desired Skills & Experience:

1. Experience leading SRE transformations.
2. Hands-on expertise with Kubernetes (EKS preferred) in production.
3. Strong experience with AWS core services (EC2, EKS, RDS, S3, ALB/NLB, IAM, CloudWatch, etc.).
4. Expertise in Infrastructure as Code using Terraform and knowledge of GitOps workflows.
5. Background in observability: metrics, visualization, logging, and tracing.
6. Understanding automation, CI/CD pipelines, deployment automation, and release strategies.
7. Experience with incident management, disaster recovery, root cause analysis, and post-incident reviews.

Additional Benefits:

• Hybrid working: 1+ days a week in London office.
• Wellbeing initiatives including coaching, fitness sessions, webinars, and an annual wellbeing day.
• Subsidised gym membership.
• Private medical insurance (including dental and vision) and life assurance.
• 25 days holiday, increasing to 30 days with service.
