This is a mid-level position ideal for an IT professional who has progressed beyond entry-level support and is comfortable independently troubleshooting issues, administering business applications, and working directly with technology vendors.

The role will primarily focus on end-user support, SaaS application administration, account and access management, and vendor coordination. Experience with networking and infrastructure is a strong plus but is not required.

Key Responsibilities

• Provide Tier 1 and Tier 2 technical support for employees, including hardware, software, Microsoft 365, connectivity, printers, and business applications.
• Manage support requests from initial troubleshooting through resolution and escalate complex issues when appropriate.
• Support employee onboarding and offboarding, including computer setup, user accounts, application access, and equipment.
• Administer business applications including Agiloft, Salesforce, Infor, Microsoft 365, DocuSign, and other enterprise SaaS platforms.
• Manage application users, licenses, roles, permissions, and access.
• Troubleshoot application issues and coordinate with software vendors when additional support is required.
• Assist with application configuration, testing, upgrades, integrations, and basic workflow changes.
• Perform routine Microsoft 365 and Microsoft Entra ID administration, including users, groups, shared mailboxes, Teams, SharePoint, and OneDrive.
• Coordinate with technology vendors, managed service providers, telecommunications providers, and hardware manufacturers.
• Open and manage vendor support cases and follow issues through resolution.
• Maintain IT procedures, system documentation, vendor information, and application support documentation.
• Assist with software licensing, renewals, technology purchases, and equipment inventory.
• Assist with basic wired and wireless network troubleshooting as needed.
• Participate in IT projects and process improvements across the organization.

Qualifications

• 3+ years of professional experience in IT support, systems administration, application administration, or a related role.
• Strong troubleshooting and problem-solving skills.
• Experience supporting Windows computers and Microsoft 365.
• Experience administering or supporting enterprise SaaS or business applications.
• Experience managing user accounts, permissions, groups, and application access.
• Ability to independently manage technical issues and work directly with third-party vendors.
• Working knowledge of common IT concepts such as Active Directory/Entra ID, authentication, networking, and endpoint support.
• Strong communication, customer service, documentation, and organizational skills.
• Ability to manage multiple priorities in a fast-paced environment.

Preferred Qualifications

• Experience with Agiloft, Salesforce, Infor, or similar enterprise applications.
• Experience with Microsoft Entra ID, Exchange Online, Teams, SharePoint, and OneDrive.
• Familiarity with Single Sign-On (SSO), SAML, OAuth, and MFA.
• Experience with Cisco Meraki or other enterprise networking technologies.
• Understanding of TCP/IP, DNS, DHCP, VLANs, switching, Wi-Fi, and basic network troubleshooting.
• Experience working in a manufacturing, industrial, or multi-site environment.
• Experience with IT service management or ticketing systems.
• CompTIA, Microsoft, Cisco, ITIL, or similar certifications are a plus.

What We're Looking For

We are looking for someone who can take ownership of day-to-day IT issues rather than simply escalating them. The ideal candidate is comfortable working directly with employees and vendors, learning new applications, troubleshooting unfamiliar problems, and knowing when an issue requires escalation.

This position offers the opportunity to work across a broad range of technologies and grow further into systems, applications, networking, and IT operations.
