Senior Windows Server Administrator

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.
Senior Windows Server Administrator
Salary: £50,000 - £70,000 + benefits
Location: Southampton, 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.
