You will serve as a key technical resource across cloud, networking, security, and on-premise systems for multiple clients.

Your work will directly influence client stability, security, and overall user experience. You will resolve advanced technical issues, identify and implement infrastructure improvements, and contribute to technical projects, solution planning, and scoping. If you are looking for a senior technical role where your expertise and decisions have a visible impact on both technology and the business, this could be an excellent next step.

• Client environments demonstrate noticeable improvements in uptime, performance, and security as a result of your remediation efforts and infrastructure recommendations.
• Technical projects, including migrations, upgrades, and security initiatives, are completed on schedule with minimal client disruption, and your expertise becomes a valued part of the planning and scoping process.
• Tickets are consistently well documented, response times remain dependable, and clients have positive experiences with your communication, ownership, and follow-through.

What We're Looking For

• Approximately 4+ years of relevant hands-on technical experience, preferably within an MSP or other multi-client support environment.
• Demonstrated ability to independently diagnose and resolve complex technical issues involving Microsoft 365, Azure/Entra, Intune, Windows Active Directory, and core networking technologies.
• Practical knowledge of cybersecurity best practices, including vulnerability management, security scanning and remediation, and general security and compliance concepts.
• Strong attention to detail, sound judgment, and a practical approach to problem-solving, combined with a security-focused and team-oriented work ethic.
• Ability to effectively manage both remote support responsibilities and on-site client needs.
