Senior IT Support Specialist

Fluxergy is a rapidly growing in vitro diagnostics company innovating on the cutting-edge of laboratory testing. We’re developing the first and only multi-modal point-of-care platform that enables molecular, clinical chemistry, immunoassay, and hematology testing on the same system.  

Our platform spans many markets including the clinical, veterinary, and food safety industries. We are seeking self-motivated problem solvers who are excited to help decentralize traditional laboratory infrastructure.  

At the core of our company’s identity is a strong foundation in engineering. We take great pride in our commitment to critical thinking and pragmatic problem-solving through a modular and systemic perspective. We hold the conviction that transparent communication, coupled with the flexibility to adjust to evolving scenarios and the willingness to venture beyond familiar territories, is crucial to both our success and yours.  

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 Will Do

• Serve as the escalation point for Tier 1 support, triaging and resolving complex, multi-system, or previously unresolved incidents.
• Provide direct, high-touch technical support to executives and other VIP users, including business-critical after-hours support when needed.
• Own root-cause diagnosis for recurring or difficult hardware, software, and business-system issues across desktops, laptops, mobile devices, printers, conference room technology, and related equipment.
• Troubleshoot network infrastructure issues (including switches, wireless connectivity, and related equipment) for problems that couldn't be resolved at Tier 1.
• Diagnose and resolve advanced deployment and configuration issues on Windows and macOS devices, including enrollment or policy failures.
• Own Microsoft 365 administrative troubleshooting, including:
  • Entra ID (Azure AD) user, group, and license management; conditional access and MFA/Security Defaults troubleshooting
  • Exchange Online mailbox configuration, permissions, and mail-flow issue resolution
  • Microsoft Intune endpoint policy troubleshooting and compliance issue resolution
  • SharePoint/OneDrive permissions and access issue resolution
  • Microsoft Teams administration and issue resolution
  • Resolve escalations and exceptions related to employee onboarding/offboarding (e.g., complex license or permission conflicts, failed automated provisioning):  routine provisioning is handled by Tier 1.
  • Provide informal mentorship and technical guidance to Tier 1 support staff, helping build their troubleshooting capability.
  • May be consulted for technical input on IT projects or rollouts led by other members of the IT team, but is not responsible for project ownership or delivery.
