We are supporting a leading global technology company seeking an Infrastructure Engineer to help build, deploy and operate highly scalable systems supporting critical UK government work.

• Managing monitoring, alerting, configuration and infrastructure upgrades
• Deploying products across production environments
• Troubleshooting complex systems using observability tools and service logs
• Automating manual processes, operational workflows and runbooks
• Working with containerised environments and orchestration technologies
• Supporting infrastructure migrations and long-term scalability improvements
