Responsibilities

• Apply changes through Terraform and Ansible in the infra repository, by pull request.
• Build self-service tooling and automations for common request types, removing blockers to engineering work.
• Write and maintain runbooks for incidents affecting core infrastructure.
• Escalate to infrastructure engineering where appropriate.
• Monitor capacity and licence expiry, and resolve proactively before limits are hit.
