As a key member of our IT team, you will be the operational backbone of our infrastructure, keeping our server environments healthy and resilient. You will work in a complex, multi-client hosting environment alongside experienced IT staff, with exposure to the security and compliance disciplines specific to our industry. This is a hands-on role with genuine ownership from day one, ideal for someone who wants variety, responsibility, and a direct line of sight to the impact of their work., * Administer, monitor, and maintain a large Windows Server estate across on-premise virtualized infrastructure and public cloud environments

• Manage day-to-day backup operations: monitoring job health, investigating failures, and verifying recoverability

• Serve as a first line for infrastructure and application monitoring alerts: triage, investigate, resolve, and escalate with clear context

• Support application delivery platforms including remote desktop services, web server farms, and database environments

• Provide responsive internal user support: endpoint troubleshooting, account and access administration, and device lifecycle management

• Execute structured patching and maintenance cycles across servers and endpoints, maintaining compliance reporting

• Manage digital certificate lifecycles for client-facing web applications, tracking renewals and coordinating deployments

• Maintain accurate asset inventories, technical documentation, runbooks, and change records

• Develop and maintain scripts to automate recurring operational tasks and reporting

• Contribute to infrastructure projects, environment changes, and continuous improvement initiatives alongside senior team members

• Participate in a shared on-call rotation for production incidents

• 5+ years of hands-on experience in systems administration, infrastructure operations, or a similar IT operations role

• Strong knowledge of Windows Server administration in a production, multi-server environment

• Practical experience with server virtualization platforms and hypervisor-based infrastructure

• Experience operating enterprise backup solutions, including restore testing and recoverability verification

• Familiarity with infrastructure and application monitoring tools, including alert triage, investigation, and escalation practices

• Working knowledge of directory services, identity management, and endpoint management platforms

• Fundamental networking knowledge: TCP/IP, DNS, DHCP, VLANs, and firewall concepts

• Scripting ability for automation and reporting (PowerShell or similar)

• Strong documentation habits, with comfort producing and maintaining runbooks, change records, and procedures

Preferred Qualifications

• Experience in a SaaS, managed services (MSP), or multi-client hosting environment

• Exposure to hyperconverged infrastructure or hybrid cloud environments

• Familiarity with enterprise security tooling such as endpoint detection and response, log analysis, or SIEM/SOC workflows

• Experience with load balancing, reverse proxy, or application delivery technologies

• Understanding of database server administration fundamentals

• Awareness of compliance frameworks such as PCI DSS or ISO 27001 in an operational context

• Relevant certifications: Microsoft (Azure/Windows Server), CompTIA (Security+, Network+, Server+), or network and security specific credentials

• Experience contributing to CI/CD pipelines or infrastructure automation initiatives

Personal Attributes

• Hands-on and independent. You take ownership of problems and see them through without needing constant direction.

• A methodical troubleshooter. You isolate variables, read the logs, and work from evidence rather than guesswork.

• Genuinely curious. You want to understand why systems behave the way they do, not just restore service.

• Organized and consistent. Documentation, change records, and follow-through are habits, not afterthoughts.

• Calm under pressure. Production incidents focus you rather than rattle you.

• Always simplifying. You notice repetition and look for ways to automate or eliminate it.

• Security-minded by default. Least privilege and auditability are part of how you think, not a checklist.

• A clear communicator. You keep the right people informed with the right level of detail.
