Responsibilities

  • Serve as the sole onsite IT resource in NYC, providing white-glove technical support to C-suite executives and end users across phone, email, chat, and in-person channels.

  • Administer and maintain Microsoft 365, Active Directory, Okta, Microsoft Entra ID, and Intune for identity management, device lifecycle, and endpoint compliance.
  • Manage the provisioning, configuration, shipping, and lifecycle of IT equipment for U.S. and international employees, including coordinating customs for global shipments.
  • Support and maintain conference room technology, Zoom Rooms, Microsoft Teams Rooms, A/V equipment, Wi-Fi, VPN, and office infrastructure.
  • Manage Help Desk tickets with timely resolution, clear communication, and SLA adherence.
  • Perform routine system maintenance, patch management, software deployments, and endpoint updates.
  • Partner with vendors including Okta and others to resolve technical issues and manage contracts and licensing.
  • Leverage PowerShell or other automation tools to streamline and improve IT operations.
  • Maintain accurate IT asset inventory, documentation, and support procedures.
  • Support remote onboarding and offboarding for new hires across global offices.

Qualifications

  • 5 years of hands-on IT support or systems administration experience in a corporate environment.
  • Strong proficiency across Windows and macOS environments.
  • Hands-on experience with Microsoft 365, Okta, Microsoft Entra ID, Azure and/or AWS, Intune, Active Directory, and SharePoint.
  • Experience supporting international or globally distributed users, including remote provisioning and equipment shipping.
  • Solid understanding of networking fundamentals including VPN, TCP/IP, DNS, DHCP, Wi-Fi, and firewall concepts.
  • Experience configuring and supporting video conferencing and conference room technology (Zoom Rooms, Microsoft Teams Rooms).
  • Strong vendor management and communication skills; comfortable negotiating and managing third-party relationships.
  • Proficiency with PowerShell scripting or other automation tools.
  • Executive presence and polish comfortable working directly with and supporting senior leadership in-person.
  • Excellent communication, interpersonal, and organizational skills with a metric-driven, detail-oriented mindset.
  • Associate's or Bachelor's degree preferred.
