Remote within the United States. Open to candidates in Minnesota and Colorado, with preference given to candidates near Mankato, MN;

About Us We are a cybersecurity-focused Managed Service Provider helping businesses get more value from technology. We provide managed IT services, cybersecurity, Microsoft 365 and cloud solutions, network infrastructure, business continuity and disaster recovery, compliance support, and strategic technology consulting. We do not outsource our technical support. Our engineers work directly with our clients and collaborate closely as a team. We value technical ability, extreme ownership, continuous learning, strong communication, accurate documentation, security, and exceptional client service.

About the Role We are looking for an experienced Level 3 Systems Engineer who can solve complex technical problems, design and implement solutions, lead projects, mentor other technicians, and serve as a senior technical escalation resource. This position combines advanced Tier 3 technical support with systems engineering, cloud infrastructure, networking, cybersecurity, and project responsibilities.

• Hybrid Active Directory and Microsoft cloud environments

You must be able to walk into an unfamiliar Windows Server environment, determine how it is configured, identify problems, and independently develop a solution.

Microsoft 365, Azure, and Cloud Engineering Modern client environments increasingly combine traditional infrastructure with cloud-hosted services. You must be comfortable supporting both, including traditional Active Directory, hybrid Active Directory and Entra , and cloud-only environments. You will:

• Administer and troubleshoot Microsoft 365 environments, including Exchange Online, SharePoint Online, Microsoft Teams, and Microsoft Intune
• Administer Microsoft Entra , including identity, roles, authentication, MFA, and Conditional Access
• Support and troubleshoot Microsoft Azure and cloud-hosted infrastructure, including virtual machines, storage, networking, identity, connectivity, servers, applications, and…
