Job description

We're looking for a Senior DevOps Engineer to own and evolve the AWS EKS platform behind our cloud-native microservices application. You'll be the go-to person for infrastructure, Kubernetes, deployments, and observability, working closely with development teams to keep things fast, secure, and reliable.

What You'll Do

• Design, operate, and scale AWS infrastructure (EKS, EC2, ECR, S3, RDS/Aurora, VPC, IAM, CloudWatch) across Dev, Test, UAT, and Production.
• Run and troubleshoot Kubernetes on EKS: deployments, networking, storage, RBAC, scheduling, and Karpenter-based autoscaling across ARM64/AMD64.
• Build and maintain infrastructure as code with Terraform and Terragrunt across multiple environments.
• Develop and maintain Helm charts, manage releases, and troubleshoot deployment issues across services.
• Build and run GitLab CI/CD pipelines - builds, scans, image publishing to ECR, and environment promotion - including Kubernetes-based GitLab Runners.
• Stand up and maintain observability: OpenTelemetry, SigNoz, the ELK stack, and dashboards/alerts for logs, metrics, and traces.
• Champion least-privilege IAM, IRSA/Pod Identity, and OIDC-based auth over long-lived credentials.
• Own production incidents end-to-end and drive root-cause fixes, not just workarounds.

What You'll Bring

• 5+ years in DevOps / Cloud / Platform Engineering, with real production ownership.
• Strong hands-on AWS: EKS, EC2, ECR, S3, RDS/Aurora, ElastiCache/Redis, IAM, VPC, ELB, CloudWatch, Secrets Manager.
• Deep Kubernetes and EKS administration and troubleshooting skills.
• Terraform (Terragrunt experience is a strong plus).
• Hands-on Helm chart development and release management.
• GitLab CI/CD pipeline design and GitLab Runner management.
• Solid understanding of IAM, RBAC, OIDC, IRSA/EKS Pod Identity, and security scanning (Trivy, GuardDuty).
• Observability experience: OpenTelemetry, SigNoz, Elasticsearch, Kibana, Filebeat, Prometheus/Grafana.
• Comfortable with PostgreSQL/Aurora and Redis.
• Bash/Shell scripting (Python a plus) and solid Git fundamentals.

Nice to Have

• Production EKS at scale, with Karpenter and ARM64/Graviton workloads in a enterprise environment
• Terraform module development and Terragrunt-based multi-environment design.
• Istio TLS and ingress security.
• Container hardening and vulnerability remediation.
• Experience troubleshooting distributed microservices architectures.
• Experience with AWS networking and load-balancer architecture
