• Managing cloud (AWS) environments, including provisioning via infrastructure-as-code (e.g. Terraform or CloudFormation).
• Supporting configuration and migration from CityFibre systems, including replacement systems such as a Network Monitoring System (e.g. Zabbix, LibreNMS or Observium), NetBox (IPAM/DCIM), centralised logging (e.g. rsyslog, Graylog or the ELK stack), DNS (e.g. BIND or PowerDNS) and an ITSM platform (e.g. ServiceNow or Jira Service Management).

• Maintaining configuration compliance and a reliable patching cadence across the estate using configuration-management and automation tooling (e.g. Ansible or Puppet).

• Strong scripting (e.g. Bash, Python) and automation ability (e.g. Ansible, Terraform).
• Methodical approach to patching, compliance and change.
