The current environment names AWS, Google Cloud, BigQuery, Terraform-based IaC, GitHub, MySQL, Redis, Elasticsearch, PHP/Laravel and Vue.js. Applicants need at least three years designing, building and maintaining infrastructure with AWS or Google Cloud, hands-on IaC experience such as Terraform, and experience designing security and scalability in cloud environments.
