End‑User Support & Onboarding

• Provide Tier 2/Tier 3 support for employees across headquarters and global offices via ITSM ticketing system, resolving escalations within agreed SLAs
• Own IT onboarding and offboarding — account creation, license assignment, virtual desktop entitlements, equipment provisioning/imaging, and timely deprovisioning
• 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

Telephony & Networking

• 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

Security & Documentation

• 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

Qualifications

• 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
