About the role
As a Senior IT Support Specialist at Fluxergy, you will serve as the primary escalation point for complex, ambiguous, or business-critical technical issues that Tier 1 support cannot resolve. You bring deep, independent technical judgment to troubleshooting across end-user computing, Microsoft 365 administration, and networking, and you're relied on to own tickets through root-cause resolution, not just triage them. This role is ideal for an experienced IT support professional who thrives on solving the hard problems, supporting executives and critical business functions with confidence, and providing informal technical guidance to less experienced team members. You will work closely with a small, collaborative IT team supporting approximately 100 employees across manufacturing, engineering, and corporate functions.
What you'll bring
- 6-8 years of experience supporting Windows-based desktop environments, with demonstrated progression into complex/escalated issue resolution.
- Hands-on experience administering Microsoft 365 services (Entra ID, Exchange Online, Intune, SharePoint/OneDrive, Teams), not just supporting end users on M365 apps.
- Demonstrated ability to work independently and exercise sound judgment on ambiguous or undocumented issues, owning tickets through resolution without close supervision.
- Excellent verbal and written communication skills, including experience communicating with and supporting executive-level stakeholders.
- Strong customer service mindset and ability to work effectively with employees at all levels of the organization.
- Ability to prioritize and manage a mix of escalated tickets and ad hoc requests in a fast-paced environment.
- Associate degree in Information Technology or related field, or equivalent work experience.
- Occasional ability to move, install, lift, and transport IT equipment as needed.
- Microsoft 365 Certified: Endpoint Administrator Associate, Microsoft 365 Certified: Modern Desktop Administrator, or Security, Compliance, and Identity Fundamentals (SC-900)
- Advanced experience with ticketing/incident management systems such as ManageEngine ServiceDesk
- Intermediate-to-advanced networking troubleshooting experience
- Strong macOS administration and troubleshooting experience
