TalentoHC is partnering with a leading travel and tourism organization seeking a System Administrator, IT Services to join its global IT team. This role is responsible for the day-to-day administration, support, and reliability of core infrastructure and end-user computing — keeping employees productive across headquarters and global offices. Unlike the cloud/network/security-focused counterpart role, this position is centered on hands‑on infrastructure support across VMware virtualization, Citrix Cloud, Microsoft 365, Active Directory/Entra , endpoint management, and telephony.

The ideal candidate pairs solid technical depth with strong customer service instincts and a commitment to clear documentation and reliable follow‑through.

• Administer Citrix Cloud environment including virtual desktops, delivery groups, machine catalogs, image updates, and end‑user session troubleshooting
• Provision, patch, monitor, and maintain Windows Server and select Linux servers on‑premises and in Azure/AWS, including backup verification
• Manage backup and recovery jobs across VMs, Microsoft 365, and file servers; verify successful completion and perform periodic restore tests

• Administer Microsoft 365 services — Exchange Online, Teams, SharePoint, One Drive — including mailbox management, distribution lists, licensing, and collaboration configuration
• Administer Active Directory and Microsoft Entra  — user and group lifecycle, Group Policy, Conditional Access, MFA, and hybrid identity synchronization
• Manage Windows and macOS endpoints via Microsoft Intune — enrollment, compliance policies, software deployment, patch management, and remote remediation
• Administer iOS and Android mobile devices via Intune

• Provide Tier 2/Tier 3 support for employees across headquarters and global offices via ITSM ticketing system, resolving escalations within agreed SLAs

• Support audiovisual and meeting‑room technology including Microsoft Teams Rooms and conference room AV
• Coordinate with vendors and MSPs (VMware, Citrix, Microsoft, Cisco, Dell, Lenovo, Apple, ISPs) for procurement, warranty service, and support cases

• Administer 8x8 telephony — user provisioning, call routing, ring groups, voicemail, and call‑quality troubleshooting
• Support Cisco network infrastructure including switches, routers, wireless, and VPN; perform first‑line troubleshooting and partner with the network team for changes beyond scope
• Support core office infrastructure — LAN, Wi‑Fi, VPN, firewalls — and maintain reliable connectivity across locations

• Enforce IT hygiene standards in partnership with Security — MFA enrollment, EDR/AV, encryption, USB policy, phishing remediation, and least‑privilege access
• Perform regular patching and vulnerability remediation across hypervisors, servers, network devices, and endpoints
• Maintain accurate IT asset records — hardware inventory, software and cloud licensing, warranty tracking, and decommissioning
• Document procedures, runbooks, and knowledge‑base articles; keep documentation current as the environment evolves

• Associate's or Bachelor's degree in IT, Computer Science, Information Systems, or equivalent experience
• 3–5 years of professional experience in system administration or infrastructure support beyond Tier 1 Help Desk
