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.

• Lead the modernization of the network environment toward a single‑vendor, single‑pane‑of‑glass architecture (for example, Cisco Meraki) designed for high availability, including resilient firewalls, N+1 switching, wireless, certificate‑based Wi‑Fi, and built‑in SD‑WAN
• Establish centralized logging and integrate a Security Information and Event Management (SIEM) solution to correlate signals across identity, endpoint, cloud, and network, reducing time to detect and respond and supporting incident response
