CI/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.

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).
