Technical Operations Specialist

Role Overview:

We are a team of driven and passionate colleagues that strive for top quality. A performance-driven work culture through collaborative review and feedback. Exposure to complex & challenging projects within an international context.

As a Technical Operations Specialist, you will keep the datacenter and multi-site store infrastructure of our international enterprise client healthy, secure and available, day to day.

You will own monitoring, patching, backups, user and print support, certificate hygiene and first response on incidents across a Windows Server, Hyper-V cluster, Active Directory and internal PKI environment.

Key Responsibilities:

Daily

• Monitor cluster, node and VM health (Failover Cluster Manager, iDRAC alerts, storage, CPU/RAM on session hosts).
• Review AD replication and domain controller health (repadmin, dcdiag), separating expected noise from real issues.
• Monitor business-critical application pools and cloud IoT connections to catch resource or port exhaustion before customers are impacted.
• Confirm overnight backups completed and investigate any failure the same day.
• Triage the IT queue: password resets, account changes, remote access, store printer and PIN pad issues.
• Review endpoint security alerts and act on detections.

Weekly

• Check PKI health: CRL validity on LDAP and HTTP CDPs, upcoming certificate expiries.
• Review store connectivity across site firewalls and site-to-site VPN tunnels.
• Audit RDS session hosts for stray local print queues and session issues.
• Review event logs for recurring Kerberos, NETLOGON or TCP/IP errors.
• Update the environment reference document and incident log.

Monthly

• Patch Windows servers in a maintenance window, one cluster node and one DC at a time.
• Update Dell firmware and drivers via Lifecycle Controller, as approved.
• Test a restore from backup (a file, a VM, a SQL database in rotation).
• Review AD accounts: disabled users, stale computers, privileged group membership.
• Report on uptime, incidents, open tickets and certificate expiries.

As needed

• First response on incidents: diagnose, contain, escalate and write the post-incident note.
• Raise change requests with a rollback plan for any change touching production.
• Onboard and offboard staff and store sites.

Required Qualifications:

• 3+ years administering Windows Server (2019/2022/2025) in a production environment.
• Hands-on Hyper-V experience, ideally with failover clustering, and Dell server management (iDRAC).
• Solid Active Directory, DNS, DHCP and Group Policy skills; comfortable with repadmin, dcdiag and nltest.
• Remote Desktop Services: session hosts, logon scripts and printer management.
• PowerShell for day-to-day administration and simple automation.
• Networking fundamentals: TCP/IP, VLANs, site-to-site VPN and firewall rules.
• IIS basics: sites, bindings, app pools and SSL certificates.
• Disciplined about change control, documentation and backups.
• Excellent written & spoken English communication; comfortable working directly with international stakeholders.
• Willing to be available round the clock as per business needs, including incident response outside regular hours.
