Job description

As a Tier 3 Support Engineer, you'll be the technical backbone of our service desk — resolving escalated tickets, mentoring Tier 1 and 2 technicians, and working directly with clients to solve complex system, infrastructure, and networking issues. You'll split your time between remote troubleshooting, on-site client visits, and project work, playing a key role in keeping clients' environments secure, stable, and running smoothly.

Compensation:

$70,000 - $90,000 yearly


Responsibilities:

  • Serve as the escalation point for Tier 1 and 2 technicians on complex tickets involving servers, networks, and end-user systems

  • Diagnose and resolve issues across Windows Server, Active Directory, Azure AD/Entra ID, Microsoft 365, and virtualization platforms (Hyper-V/VMware)

  • Manage and troubleshoot network infrastructure including firewalls, switches, VPNs, and Wi-Fi (e.g., Cisco, Ubiquiti, Meraki)

  • Support and maintain backup/disaster recovery solutions, and participate in DR testing

  • Administer and troubleshoot cloud environments (Azure, AWS) and hybrid infrastructure

  • Perform patch management, security hardening, and endpoint protection oversight across client environments

  • Document solutions, standard operating procedures, and network diagrams in our PSA/RMM and knowledge base

  • Participate in client onboarding, infrastructure assessments, and technology roadmap planning

  • Assist with project work such as server migrations, M365 tenant migrations, and network upgrades

  • Provide occasional after-hours/on-call support on a rotating basis

  • Mentor and train junior technicians, helping build team-wide technical capability


Qualifications:

  • 5+ years of experience in an MSP or IT support environment, with demonstrated Tier 2/3 responsibilities

  • Strong knowledge of Windows Server administration, Active Directory, DNS/DHCP, and Group Policy

  • Hands-on experience with Microsoft 365 / Azure AD administration

  • Solid understanding of networking fundamentals (TCP/IP, VLANs, routing, VPNs, firewalls)

  • Experience with RMM and PSA tools (e.g., ConnectWise, Axcient, NinjaOne, Kaseya) a plus

  • Familiarity with virtualization technologies (Hyper-V, VMware) and cloud platforms (Azure, AWS)

  • Working knowledge of backup and business continuity solutions (Axcient, Veeam, etc.)

  • Excellent troubleshooting, documentation, and communication skills

  • Comfortable working directly with clients, including non-technical stakeholders

  • Relevant certifications preferred (e.g., CompTIA Network+/Security+, Microsoft MS-102, Azure Administrator, CCNA)

  • Valid driver's license and reliable transportation for occasional on-site client visits
