• Write and maintain automation and operational scripts using Python, Bash, and/or PowerShell

• Manage and collaborate on code using Git (GitLab preferred), following best practices for version control and code review

• Contribute to improving platform standards, documentation, and operational processes

Skills and Experience

• Proven experience as a DevOps Engineer, Site Reliability Engineer, or similar role

• Strong experience with AWS cloud infrastructure

• Hands‑on experience with Infrastructure as Code, ideally AWS CloudFormation

• Experience with version control systems, particularly Git

• Familiarity with CI/CD concepts and tooling

• Ability to write scripts and automation using at least one of Python, Bash, or PowerShell
