Key Responsibilities

Design and manage infrastructure using AWS, Kubernetes, and Terraform, with a focus on Terraform module design, remote state management, and policy-as-code.
Implement GitOps practices using tools like Flux or Argo CD for declarative, version-controlled environment management and drift detection.
Take ownership of Kubernetes as a Service (KaaS) platforms, including multi-cluster lifecycle management, version upgrades, and advanced autoscaling strategies.
Troubleshoot complex traffic flows and optimize cloud networking, including CNI configurations, ingress controllers, and load balancing.
Build and support CI/CD pipelines to enable efficient and reliable deployments.
Automate infrastructure provisioning and configuration using tools like Ansible, Puppet, or Chef.
Write and maintain infrastructure-as-code and configuration-as-code for all environments using Terraform.
Monitor, troubleshoot, and optimize infrastructure performance, availability, and cost.
Integrate and manage third-party tools, plug-ins, and internal scripts as needed.
Create and maintain technical documentation, including runbooks and architecture diagrams.
Participate in on-call rotations and contribute to improving incident response processes.
Collaborate cross-functionally to ensure infrastructure meets application and business needs.
