- Operate and optimise our AWS workloads (networking,



compute, storage, security groups, IAM) with a focus on reliability, cost efficiency and scalability.
- Manage Windows servers primarily related to IIS web hosting and Active Directory, including configuration, patching and troubleshooting.
- Configure and maintain secure network connectivity, including VPNs, firewalls and VLANs, in close collaboration with network and security stakeholders.
- Build and maintain observability for our platform using Grafana and Prometheus/Loki, ensuring we have the right dashboards, alerts and metrics in place.
- If/when knowledge and experience allow, contribute to and maintain OpenStack, TeamCity build and deployment pipelines (where relevant) to support predictable and automated releases.
- Collaborate with development, support and product teams to understand requirements, troubleshoot platform issues and improve reliability and performance.
