Senior Windows Server Administrator in Southampton

A global technology business is looking for a Senior Windows Server Administrator to become the go-to escalation point for complex Wintel infrastructure issues. This is a role for someone who enjoys deep technical troubleshooting, not just keeping the lights on. You will be joining a business with a sizeable, established technology environment and current projects including a move from VMware towards Azure Local, alongside wider infrastructure integration work across newly acquired sites. The role is based in Southampton and is office based.

You will take ownership of complex Windows Server and infrastructure challenges, supporting a broad environment covering server, virtualisation, storage, file, email and collaboration technologies. The business needs someone who can be trusted as a senior technical escalation point, particularly when incidents are high priority, time-sensitive, or visible to senior stakeholders. This is not a role for someone who only wants to follow runbooks. You will be expected to understand how systems fit together, diagnose issues under pressure, explain your thinking clearly, and help less experienced administrators develop their own technical capability.

In the role, you will:

• Lead troubleshooting across Windows Server environments
• Act as a senior escalation point for complex infrastructure issues
• Support projects involving virtualisation and hyper-converged infrastructure
• Contribute to the move from VMware towards Azure Local
• Work across technologies including server, storage, file, email and collaboration systems
• Help define technical priorities, improvements and roadmap activity
• Mentor other IT Administrators within the team
• Support security, resilience, capacity and regulatory requirements
• Research new technologies and recommend practical, cost-effective solutions

The most important requirements are strong Windows Server experience and excellent troubleshooting ability. You should be confident investigating issues properly, using tools such as event logs, understanding areas such as Active Directory, Group Policy, replication, certificates and wider infrastructure dependencies.

You do not need to have worked with every technology listed below, but experience across any of the following would be useful:

• VMware, Hyper-V or Azure Local
• Citrix
• SCCM / MECM
• Exchange
• Thycotic
• Zabbix or other enterprise monitoring tools
• Agile working environments

You will need to be able to travel within Europe without restriction when required.

Benefits include:

• Up to 26 days holiday, plus bank holidays
• Additional birthday and work anniversary celebration days after probation
• 5% employer pension contribution
• Employee share purchase scheme with discounted shares
• Private medical, healthcare cash plan and Digital GP access
• Life assurance, income protection and critical illness cover

The interview process is two stages: an initial 30-45 minute Teams call, followed by an onsite interview in Southampton.
