Maintain software-defined, declarative infrastructure at scale using automation tools such as Ansible and GitLab.
Perform software upgrades, version control, and security patching across production systems.
Proactively analyze network metrics such as capacity, latency, and availability to detect and prevent outages.
Support network operations in private and hybrid multi-cloud environments (e.g., Azure, AWS, GCP).
Partner with the Site Reliability Engineering (SRE) team to improve operational processes and reliability.
Review, consult, and prepare for planned changes and releases to the production environment.
Create and maintain detailed documentation of infrastructure, automation, and standard operating procedures.
