What you will do

• Run and scale multi-tenant Kubernetes client environments on AWS EKS across multiple accounts and regions, maintaining strong isolation and sensible resource sizing.
• Extend monitoring and alerting with Prometheus, Grafana, Loki, and OpenTelemetry, while improving service ownership of alerts and service levels.
• Maintain fast, predictable CI/CD and GitOps-based deployments so engineers can ship safely and frequently.
• Design graceful failure handling with service engineers, including retries, resource limits, queue handling, recovery, and incident prevention.
• Improve infrastructure and compute efficiency, understand the cost of each client environment, and support the addition of new clients through automation.
• Participate in a compensated out-of-hours incident rota optionally and contribute to post-incident improvements.

Requirements

• Several years of experience running production infrastructure on AWS, including EKS, IAM, and networking across multiple accounts and regions.
• Strong Kubernetes expertise beyond the basics, including multi-tenancy, Helm, scaling behaviour, and cluster performance under pressure.
• Ability to write maintainable Terraform that other engineers can safely change, applying application-code quality standards to infrastructure code.
• Programming experience with Python, Go, or a comparable language, sufficient to automate systems, build small services and controllers, and read supported applications.
• Experience building or operating CI/CD systems and using GitOps to manage deployments.
• Experience operating data-heavy systems, including message queues, search clusters, and high-volume pipelines that must not silently lose data.
• Incident response experience with a focus on learning from incidents and preventing recurrence.
• Ability to collaborate effectively with product engineers and help other teams work faster and more safely.
• Pragmatic judgement about what to automate, what to leave alone, and how to choose under time pressure.

Nice to have

• Experience with AWS and Azure, Kubernetes, EKS, Karpenter, Terraform, Helm, FluxCD, GitHub Actions, Prometheus, Grafana, Loki, OpenTelemetry, Kafka, Elasticsearch, PostgreSQL, ClickHouse, Python, and Go services; deep expertise in some of these technologies is sufficient.
