• Use declarative frameworks like Terraform and Ansible to build, manage, and configure infrastructure such as AWS, Kubernetes, Git, TeamCity, Concourse, and GitHub Actions.
• Research and implement new technologies to enhance network and compute performance, container management, workload orchestration, and cloud integration.
• Support the business by maintaining and managing storage requirements on NFS, CIFS, and S3 compatible systems within a Linux-based environment.
• Support and enhance highly available database architectures, ensuring systems are up-to-date with minimal downtime, following best practices, and coordinating with Database Administrators for updates and architectural improvements.
