Lead DevOps Engineer

Job Purpose

We are seeking a Lead Site Reliability Engineer to lead the adoption of Infrastructure as Code (IaC), automation, and GitOps practices across our AWS cloud environments. This role will be instrumental in transforming traditional cloud operations into a scalable, code-driven operating model by eliminating manual processes, improving reliability, and driving automation across infrastructure and platform services.

 This position will also play a key role in mentoring team members and establishing best practices for cloud infrastructure, automation, and operational excellence.

  · Build and maintain reusable Terraform modules for AWS resources (VPCs, EC2, EKS, RDS, Aurora, IAM, and more)

  · Develop and manage Ansible playbooks for configuration management across Windows and Linux fleets

  · Champion the principle that every infrastructure change flows through code and version control – no exceptions

• GitOps and CI/CD

  · Design and implement GitOps workflows using GitHub actions and/or ArgoCD for infrastructure and application deployments

  · Establish branch protection, code review gates, and automated validation pipelines for infrastructure PRs

  · Define and enforce GitOps standards across the team, onboarding colleagues to the new way of working
