Ideal Candidate Profile

The ideal candidate is a hands-on Senior Platform Engineer who has built reusable CI/CD and infrastructure patterns for application teams. This person should be able to design Terraform modules, build Jenkins shared libraries, support AWS ECS Fargate workloads, and create standardized deployment workflows across development, test, staging, and production environments.
