The candidate will also participate in advanced, code-based management of infrastructure and networking in public cloud environments, mainly AWS, including VPCs, peering, transit/VPN gateways, hybrid connectivity, and IAM.
Additional experience with Google Cloud or Azure will be valued due to the transferability of knowledge across cloud platforms.
Knowledge of database administration at infrastructure and operational level will also be valued, including relational and non-relational databases such as SQL / PostgreSQL and MongoDB. This is not an essential requirement.

## Description

We are looking for an IT Infrastructure System Administrator to support the operation, maintenance, and continuous improvement of hybrid corporate environments, combining on-premise infrastructure and public cloud services.
The role will focus on the day-to-day administration of systems, virtualization, storage, backup, critical infrastructure services, and advanced technical support for production environments.
The candidate will participate in infrastructure automation using Infrastructure as Code, mainly with Terraform for provisioning and state management, and Ansible for configuration management and idempotency, working with modular, reusable code versioned in Git.
The scope of the role is focused on infrastructure deployment and operations, not application deployment, which falls under the DevOps area.
