Systems Engineer

Level II Systems Engineer Escalations, Windows Server & Networking | Protek-IT | Chicago, IL (Hybrid) | $80K – $100K Are you the tech who gets handed the tickets L1 couldn't close, and actually enjoys it? Join Protek-IT as our Level II Systems Engineer: the escalation point for our service desk, remote and onsite, across 100+ client environments. You'll work on Windows Server, Active Directory, Group Policy, Hyper-V, networking, and line-of-business application problems, handle hands-on project work, and be the technical voice when a client needs to understand what's going on.

About the Role
You take escalations from our L1 technicians and resolve them, remotely first and on-site when needed. You also execute Level II technical tasks on client projects (server and hypervisor replacements, network upgrades, office moves), scope new work for our account manager, and join client technical reviews as the technical voice. This is not a help desk, people-management, or project management role. Our team lead coaches L1, and our dedicated project manager owns project planning, schedules, and budgets. Your job is to execute the technical work, do it right, and flag risks early. Time split: ~30% escalations and troubleshooting, ~30% project tasks assigned by the PM, ~20% scoping and assessments, ~20% client technical reviews, and the rest on documentation and internal improvements. Onsite client work is about 20% of your time.

What You'll Do
• Own escalated tickets from L1 and drive them to resolution; find the root cause and document the fix so L1 can handle it next time
• Troubleshoot Active Directory, DNS/DHCP, Group Policy, Hyper-V hosts and VMs, and Microsoft 365 mail flow and identity issues
• Diagnose firewall, VPN, switching, VLAN, and Wi-Fi problems; fix configuration and recommend redesign where needed
• Troubleshoot line-of-business applications (e.g., ERP, Sage, QuickBooks, UPS WorldShip, document management etc.) at the server, database, and client level, including upgrades
• Handle vendor escalations and coordination: open and own cases with software vendors, ISPs, carriers, and hardware manufacturers until resolved, keeping the client and team updated
• Execute Level II project tasks (staging, configuration, cutover, documentation) from the PM's plan; occasional scheduled evening cutovers
• Scope client and prospect requests, including site visits, and hand the account manager a clear scope, bill of materials, and labor estimate
• Join the account manager in client technical reviews: environment health, risks, lifecycle replacements, and next steps
• Keep client documentation current in Hudu and log time accurately in HaloPSA What We're Looking For Required:
• 3+ years handling Level II escalations in an MSP or multi-client environment, both remote and onsite
