Senior DevOps Engineer - AWS & KubernetesIn this role, you will lead the organization's containerization strategy, build enterprise-grade automation workflows utilizing GitHub Actions, and manage the Infrastructure as Code (IaC) lifecycle to ensure high availability, optimal performance, and cost efficiency. You will work closely with a team of six, driving CI/CD automation, Kubernetes cluster management, cloud infrastructure, and DevSecOps practices.
Key ResponsibilitiesCI/CD & GitHub Actions Automation- Workflow Architecture: Design, build, and optimize matrixed, self-hosted, or cloud-hosted GitHub Actions workflows for continuous integration and automated testing.
- Reusable Infrastructure: Build and maintain version-controlled custom GitHub Actions and reusable workflow templates to standardize pipelines across multiple engineering teams.
- Secret Management: Manage secure environment variables, contexts, and deployment keys using GitHub Secrets, Environments, and integrations with AWS Secrets Manager or HashiCorp Vault.
- Secure Delivery: Implement OpenID Connect (OIDC) to authenticate GitHub Actions runners natively with AWS IAM, eliminating long-lived credentials.
Kubernetes & Container Orchestration- Cluster Management: Design, deploy, and maintain multi-cluster production AWS EKS and Kubernetes environments.
- Upgrades & Maintenance: Execute seamless, zero-downtime cluster upgrades, patch releases, and routine maintenance node recycling.
- Autoscaling & Cost Optimization: Configure and tune cluster autoscaling using tools like Karpenter or Cluster Autoscaler, alongside horizontal/vertical pod autoscaling (HPA/VPA).
- Package Management: Build, maintain, and version control internal Helm charts for streamlined application delivery.
AWS Infrastructure & Automation- Infrastructure as Code (IaC): Provision and manage 100% of cloud resources using Terraform or AWS CDK to maintain strict environment consistency.
- Cloud Architecture: Administer core AWS services including EC2, VPC, IAM, S3, Route53, and RDS platforms.
- Scripting & Tooling: Write clean, maintainable automation scripts using Python and Bash to eliminate manual interventions.
GitOps & Release Management- GitOps Adoption: Implement and maintain GitOps-driven deployment frameworks utilizing tools like ArgoCD or Flux to sync EKS state with source repositories.
- Container Registry: Oversee Docker container builds, multi-stage layering, and registry vulnerability management via AWS ECR, triggered natively via GitHub Actions runner hooks.
Networking, Security, & DevSecOps- Cloud Networking: Manage sophisticated container networking interfaces (VPC CNI) and advanced ingress routing controllers (ALB, NGINX, or Traefik).
- Access Control: Enforce security guardrails utilizing AWS IAM Roles for Service Accounts (IRSA) to grant fine-grained pod permissions.
RequirementsCandidate RequirementsExperience Required- No degree required.
- 5+ years of professional experience in dedicated DevOps, Site Reliability Engineering (SRE), or cloud infrastructure roles.
- 3+ years of heavy practical experience writing, testing, and modularizing complex GitHub Actions workflows.
- 5+ years of hands-on, architecture-focused experience across major AWS services.
- 3+ years of deep technical experience running production-grade workloads on Amazon EKS, including advanced troubleshooting.
- Expert proficiency with Terraform and at least one scripting language (Python or Bash).
Preferred Qualifications- Certifications: Certified Kubernetes Administrator (CKA), CKAD, or AWS Certified DevOps Engineer Professional.
- Runner Administration: Experience managing scaling policies for enterprise-scale GitHub Actions self-hosted runners on Kubernetes (e.g., using Actions Runner Controller - ARC).
