Job Responsibilities/Objectives

Collaborate with platform engineers to develop and enhance a reusable Terraform module for GKE, including IAM policies and VPC networking configurations.
Work on solution hardening, improving security, compliance, and reliability ahead of final sign-off in the SE environment.
Migrate existing CI/CD workflows to the new strategic Harness pipeline, ensuring smooth deployment and testing processes.
