You'll be responsible for ensuring our microservices platform is reliable, scalable, and cost-efficient while empowering developers to ship with confidence. Our stack runs on AWS EKS with modern tooling including Karpenter for intelligent node scaling, KEDA for event-driven autoscaling, and Datadog for full observability. If you enjoy working with Kubernetes at scale and have a passion for automation, we'd love to hear from you. What You'll Do

• Own our Kubernetes platform: manage and evolve our AWS EKS cluster, including node pools, networking, scaling policies, and cluster upgrades.

• Build reliable CI/CD pipelines: design and maintain GitHub Actions workflows for building, testing, and deploying containerized microservices to production.
• Drive observability: own our Datadog implementation for logs, APM, metrics, and alerting-ensuring we catch issues before our users do.
• Manage secrets securely: maintain our secrets management flow using AWS Secrets Manager and External Secrets Operator.
• Support the development team: collaborate with backend engineers on Node.js/TypeScript services, helping debug performance issues and optimize deployments.
• Maintain supporting infrastructure: manage Redis clusters (used for Bull job queues), ALB ingress configuration, and DNS management.
• Implement Infrastructure as Code: use Helm, Kustomize, or Terraform to ensure our infrastructure is reproducible and version-controlled.
• Respond to incidents: troubleshoot production issues, conduct post-mortems, and implement preventive measures.
• Optimize costs: monitor and reduce AWS spending through right-size, spot instances, and efficient resource allocation.

The ideal candidate will have strong AWS and Kubernetes experience, along with excellent communication skills to work within distributed teams., * 4+ years of hands-on experience with Kubernetes (AWS EKS strongly preferred).
