In support of this growth, we are looking for a Linux Systems Administrator to support and maintain our hosted server environments.   Most of the servers run Red Hat Enterprise Linux which is virtualised using VMWare vSphere on a Cisco UCS blade infrastructure.   The role sits within the Hosted Services team whose primary objective is to maintain 24x7 performance, availability and security of our hosted services.

  • Work with the engineering/architecture teams to design solutions so as to maximize performance, efficiency and operability of hosted solutions.
  • Lead and/or participate in the provisioning and deployment of server, network and other hosting-related equipment, including hands-on build and configuration as/when required.
  • Participate in the deployment of new applications and/or changes, ensuring that all service components are monitored and integrated into the company’s operational processes.
  • Work with stakeholders across the solutions lifecycle to ensure that pre-operational sign-offs are obtained, so as to ensure that solutions can be operated in a way that meets or exceeds performance targets e.g. security, availability and response times.
  • Assist with the troubleshooting of integration issues.

Responsibilities – Operations

  • Hands-on administration and maintenance of hosted servers and related infrastructure (firewalls, switches, storage, etc.) including pro-active identification and fixing of potential incidents, backup management, etc.
  • Participate in the definition, documentation, operation and continuous improvement of operational processes e.g. ITIL-based processes such as incident, change, problem and configuration management, and the smooth integration of these with wider company processes and systems.
  • Define, implement, monitor and report on metrics that are required for the delivery of highly-available hosted services, as well as to meet the needs of the wider organization e.g. management, engineering, customer services and our customers.
  • Provide third-line technical support for all areas of hosted services, including participation on a 24x7 on-call rota; ensure the timely resolution of incidents and/or problems affecting hosted solutions and deploy approved changes and/or updates as required.
  • Track, troubleshoot and resolve hardware issues, and manage RMA processes with various vendors.
  • Support and enable the automation of hosting-related processes e.g. deployment of changes, deployment of new services, inventory management, security scanning, service level reporting, etc.
