Senior Level 3 Technician

Company Overview

We are a Milwaukee-based managed services provider (MSP) delivering end-to-end technology support and infrastructure services for a diverse set of clients. Our focus is on practical, high-quality solutions that keep our clients secure, productive, and confident in their technology.

As a growing, service-driven company, we value accountability, clear communication, and a team-first mindset. You will work directly with the owner and a close-knit service team, with real influence on how we design, deliver, and improve our services.

The Opportunity

This Senior Level 3 Technician role is ideal for a seasoned MSP engineer who thrives on solving complex problems, owning escalations, and improving client environments over time. You will be the go-to technical expert for cloud, networking, security, and on-premise systems across multiple client environments.

In this position, you will have a direct impact on client stability, security posture, and user experience. You will handle advanced issues, lead technical improvements, and contribute to projects and scoping. If you are looking for a role where your decisions matter and your work is visible at both the technical and business levels, this is a strong next step.

What You'll Do

• Independently resolve advanced technical issues and serve as the primary escalation point beyond Level 1/2 support for cloud, server, and networking incidents.
• Review, troubleshoot, and remediate complex issues across Microsoft 365, Azure, Entra (Azure AD), Intune, and on-premise Active Directory environments.
• Drive infrastructure improvement initiatives to enhance client stability, performance, and security, including network design fundamentals, VLANs, and core routing/switching concepts.
• Participate in and help execute technical projects such as cloud migrations, system upgrades, and security hardening efforts, including contributing to scoping and solution planning.
• Maintain strong ticket hygiene, documentation, and response-time discipline while collaborating with internal teams to ensure consistent, high-quality service delivery.

What Success Looks Like

• Within the first 36 months, you are the trusted escalation point for complex incidents, consistently resolving Level 3 issues without needing outside assistance.
• Client environments show measurable improvement in uptime, performance, and security posture through your remediation work and infrastructure recommendations.
• Technical projects (migrations, upgrades, security initiatives) are delivered on time with minimal disruption, and your input is sought in scoping and planning.
• Tickets are well-documented, response times are reliable, and clients consistently report positive experiences with your communication and follow-through.

What We're Looking For

• Approximately 4+ years of relevant hands-on technical experience, ideally in a managed services or multi-client support environment.
• Proven ability to independently troubleshoot and resolve complex issues in Microsoft 365, Azure/Entra, Intune, Windows Active Directory, and core networking.
• Working knowledge of cybersecurity practices including vulnerability management, security scanning and remediation, and general security and compliance concepts.
• Strong vigilance, attention to detail, and a practical problem-solving mindset, with a security-first, team-oriented work ethic and the ability to manage remote and on-site client needs.

Compensation and Benefits

• W-2 employment
• Healthcare allowance
• Full-time, on-site role in Milwaukee, WI (must be local; includes vehicle usage/SUV for driving to and from client sites)
• Standard schedule MondayFriday, 8:00 a.m. to 4:00 p.m., with possible round-robin on-call rotation as needed
