Support endpoint management platforms (Intune/SCCM) for imaging, patching, and configuration compliance.
Troubleshoot network connectivity issues including LAN/WAN, VPN, and Wi-Fi across office and remote locations.
Document recurring issues and root causes, and build knowledge base articles to improve first-contact resolution at L1/L2.
Participate in an on-call rotation for after-hours critical incident support as needed.

Maintain accurate technical documentation, including network diagrams, configuration standards, and runbooks.
Monitor system health and performance, proactively identifying and addressing potential issues.
Mentorship & Process Improvement
Mentor and provide technical guidance to Level 1 and Level 2 support engineers.
Recommend and help implement process improvements to reduce ticket volume and improve overall support quality.
Partner with cross-functional IT teams (Security, Infrastructure, Applications) on projects and escalations.
Contribute to the evaluation and rollout of new tools and technologies that improve the end-user and IT support experience.
Qualifications, Skills and Requirements:
Considerable, hands-on experience (typically 5+ years) in IT support, systems administration, or a related technical role, with demonstrated ability to independently resolve complex, escalated issues.
