COMPANY: Quanta Government Solutions
JOB TITLE: Sr IT Support Specialist
DEPARTMENT: Information Technology
LOCATION: Hybrid
REPORTS TO: Senior Manager, IT Operations
CLASSIFICATION: Exempt
POSITION OVERVIEW:
Quanta Government Solutions is seeking a Sr IT Support Specialist to serve as the escalation point for complex technical issues across our enterprise environment. This role owns Tier 3 support, administers our Microsoft 365 environment, and delivers high-quality end-user support. The ideal candidate brings deep Windows and M365 expertise, general familiarity with Azure, a customer-first mindset, and willingness to travel to field locations as needed. Beyond day-to-day escalation and administration, this role also contributes technical direction on the ongoing architecture, licensing strategy, and lifecycle roadmap of the Microsoft 365 and Azure environment.
What You'll Do
Serve as the Tier 3 escalation point for all endpoint-related issues (hardware, software, OS, and applications) unresolved by Tier 1/2, driving resolution with minimal downtime and engaging vendor support directly when the technology requires manufacturer- or vendor-level resolution.
Administer Microsoft 365 (Exchange Online, SharePoint, Teams, OneDrive, Intune, Azure AD, Defender, Purview, and licensing) and enforce endpoint security and compliance (BitLocker, MFA, Conditional Access).
Deploy, configure, and maintain Windows 11 workstations, laptops, peripherals, iOS/Android mobile devices, and Microsoft Cloud PCs; manage device lifecycle from imaging through retirement using automation and best practices, and manage Azure Virtual Desktop (AVD) environments.
Monitor endpoint health, patching, and remote support via RMM tooling (NinjaRMM or equivalent); maintain automation scripts, alerts, and device policies.
Troubleshoot core network connectivity issues (DNS, DHCP, VPN, wireless, firewall rules) and monitor backup jobs across on-prem and cloud workloads, performing restores and escalating to network/security teams as needed.
Communicate technical solutions clearly to non-technical users; act as a trusted technology advisor to staff and leadership.
Participate in a shared on-call rotation providing after-hours and weekend support for critical outages; assist with Tier 1/2 tickets during peak volume, backlogs, or staff absences.
Travel to company sites and project locations for on-site support, installations, and technology deployments.
Provide architectural input and recommendations on the Microsoft 365 and Azure platform roadmap, partnering with IT leadership on endpoint management strategy, tenant configuration standards, and technology lifecycle planning.
Own software and cloud licensing budget planning for supported platforms, including cost forecasting, vendor contract review, and renewal negotiation.
Own and maintain IT support SOPs and process documentation, leading process-improvement initiatives across the support organization.
