  Soft, including monitoring, optimisation and full or granular restores.

• Support Plesk and cPanel hosting platforms, covering web, DNS, email, databases, SSL certificates and PHP versions.

• Carry out website, server and hosting migrations between platforms and data centres.

• Work with MySQL/MariaDB and SQL Server, supporting database restores, performance troubleshooting and customer investigations.

• Monitor infrastructure using Zabbix, LibreNMS and associated platform tools, investigating alerts and contributing to capacity planning.

• Contribute to infrastructure projects involving Open Nebula, AWS backup solutions and hosting platform improvements.

• Develop automation using Power Shell, Bash and Python to improve efficiency and reduce manual administration.

• Act as a 3rd-line escalation point, providing root cause analysis, customer updates and structured change plans.

• Maintain technical documentation, runbooks and SOPs to improve support processes and knowledge sharing.

• Proven experience in a Systems Administrator, Infrastructure Engineer or similar technical role.

• Strong Windows Server and Linux administration skills, ideally including RHEL, CentOS and Ubuntu.

• Hands‑on experience with VMware vSphere/ESXi and/or KVM-based virtualisation.

• Experience with backup and disaster recovery platforms such as Veeam and R1
  
  Soft.

• Knowledge of hosting control panels such as Plesk and cPanel.

• Familiarity with web hosting technologies, DNS, SSL, email services and database administration.

• Scripting experience with Power Shell, Bash and/or Python.

• Experience with infrastructure monitoring tools such as Zabbix or LibreNMS.

• Strong troubleshooting skills, with the ability to investigate complex technical issues and identify root causes.

• An understanding of ITIL processes, change management and security standards such as ISO 27001.

• Salary: £40,000-£50,000

• Location: Nottingham, with hybrid working (3 days on-site)

• Contract: Full-time, permanent

If you're a technically strong Systems Administrator looking for a role where you can take ownership of complex infrastructure, improve existing platforms and get involved in wider technical projects, I'd be keen to hear from you.
