\n The ideal candidate is a technical authority who has owned infrastructure and cloud initiatives, rather than someone focused primarily on user support or administration. The role has significant hands-on responsibility across Azure, Microsoft 365, Intune, Entra ID, and Windows infrastructure, while also serving as a senior escalation point for the broader IT environment. \n

\n The environment is fast-paced and highly executive-facing. The successful candidate will be comfortable making independent technical decisions, troubleshooting complex issues, applying security policies in real time, and working directly with senior leadership. Third-party vendors provide specialized support in areas such as networking, security, and AV, so the expectation is broad technical fluency rather than deep specialization in every discipline. \n
