General Statement of Job:
The Senior Manager of IT Infrastructure leads the strategy, security, and continuous improvement of SIS''''''''s cloud-first IT infrastructure across the Americas. This leader owns the company''''''''s Cloud, Systems Administration, Networking, and Help Desk functions and is accountable for advancing SIS''''''''s Zero-Trust strategy, in which all access is verified, identity is the perimeter, and the environment is centrally managed, monitored, and documented. SIS operates a predominantly Apple environment (approximately 90% macOS) supporting a 24/7 Global Security Operations Center, so the ideal candidate pairs senior leadership ability with hands-on depth in modern cloud, identity, endpoint, and network platforms. Working within an ITIL-based operational framework, the Senior Manager of IT Infrastructure sets technical direction, develops the team, guides IT policy and purchasing decisions, and partners with leadership to deliver a reliable, secure, and scalable platform. This role reports directly to the Director of Technology.
This position leads a multi-site team that includes a Help Desk Manager, Help Desk Staff, Systems Administrator, Network Administrators, and the newly created Senior Cloud Administrator roles across Culver City, Austin, Seattle, San Jose, New York, and LATAM.

- Provide expert oversight and technical direction for enterprise cloud and SaaS platforms, including Google Workspace, Box, AWS, and Microsoft Azure, ensuring availability, performance, security, and data governance
