A long-tenured IT leader is retiring, and this firm needs a hands-on player-coach to step in. It is not a people-manager seat. You'll still do the senior systems work every day while leading and mentoring a small desktop support team. The environment is about 85% Windows and 15% Linux, supporting roughly 170 people.

What you'll own

• Active Directory and Entra ID: group design, service accounts, SPNs, app registrations, Graph API access and credential rotation
• Microsoft 365 and Exchange Online: mail routing, mail security, DLP, retention, Teams, SharePoint and OneDrive
• VMware vSphere and the Windows Server estate, plus physical servers (racking, cabling, diagnostics, part swaps)
• Windows and Samba file servers: permissions, quotas, capacity and migrations
• Networking and firewalls: TCP/IP, DNS, DHCP, VLANs, wireless, certificates and monitoring
• Security: endpoint protection, MFA, conditional access, phishing simulations and alert response
• IT controls in an audited environment: monthly access reviews, change management, exceptions and DDQ support
• eDiscovery and legal hold searches with Legal and Compliance
• Avaya PBX support and the move to an outsourced voice provider
• Licensing, renewals and vendor management (M365, Adobe, Box, Bloomberg, Verizon and more)
• Server room power and cooling: UPS, PDUs, HVAC and coordination with building vendors
• PowerShell and Python automation
• Leading and mentoring the desktop support team and serving as the top technical escalation point

What you bring

• 7+ years of hands-on enterprise infrastructure experience
• Deep Windows Server, AD, M365 and MFA knowledge
• Real experience with service accounts, Entra app registrations and credential management
• VMware vSphere
• A secure email gateway such as Proofpoint or Mimecast
• Endpoint and data-governance tools such as CrowdStrike or Varonis
• Strong PowerShell
• Experience running IT controls in a regulated or audited setting
• Experience leading projects with MSPs and vendors from start to finish

Nice to have

• Financial services background
• eDiscovery or legal hold experience
• Bloomberg administration and entitlements
• Avaya PBX experience
• AWS or Azure
• Ansible or PowerShell DSC

The details

• 100% onsite in NYC, with travel to CT and the firm's Westchester DR site as needed (transportation covered)
• Occasional after-hours work for patching and recovery testing
• US citizens only
