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. SIS operates a predominantly Apple environment (approximately 90% macOS) supporting a 24/7 Global Security Operations Center. This role 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 position leads a multi-site team across multiple locations.
Responsibilities
- Lead and develop the Cloud, Systems, Networking, and Help Desk teams across North and South America, ensuring cohesive, efficient operations aligned with business needs and the technology roadmap.

- Own the identity and access management strategy, directing the migration to a centralized Identity and Access Management platform.
- Provide expert oversight and technical direction for enterprise cloud and SaaS platforms, including Google Workspace, Box, AWS, and Microsoft Azure.
- Direct endpoint and security management across a predominantly Mac environment, including JAMF for Apple device management, Windows MDM, and SentinelOne.
- Lead the modernization of the network environment toward a single-vendor, single-pane-of-glass architecture designed for high availability.
- Establish centralized logging and integrate a Security Information and Event Management (SIEM) solution.
- Mature the ITIL-aligned operational framework—incident, problem, change, and configuration management—and drive the development of documented policies, procedures, and runbooks.
- Own and drive best-in-class disaster recovery, business continuity, data protection, and backup strategies that support SIS's 24/7 enterprise.
- Partner closely with Security Operations Center (Fusion Center) leadership to deliver a unified physical and information security strategy.
- Drive lifecycle management and remediation initiatives across endpoints, infrastructure, and cloud services.
- Maintain accurate documentation of the environment and support audit and compliance objectives such as ISO 27001 and SOC 2.
- Collaborate with cross-functional teams and senior leadership to plan and execute major infrastructure projects, upgrades, and migrations.
- Act as the principal liaison for vendor negotiations on license renewals and hardware refreshes, optimizing expenditures.
- Mentor, train, and develop IT personnel, setting clear performance goals, objectives, and growth plans.
- Provide weekly, monthly, quarterly, annual, and ad hoc reporting on systems and team KPIs and other metrics.
- Communicate complex technical information clearly to both operational security staff and senior executive leadership.
- Manage the departmental budget for infrastructure and operational expenditures.
- Perform other related duties as required.
Requirements
- Bachelor's degree in Information Technology, Computer Science, or a related field; equivalent combination of education and professional experience will be considered.

- Demonstrated experience leading cloud-first IT infrastructure in a predominantly Apple/macOS environment (approximately 90% Mac) with some Windows.
- Deep experience deploying and administering enterprise SaaS and cloud platforms (such as Google Workspace, Box, AWS, and Azure).
- Proven experience with modern identity and access management, including Active Directory/Entra ID and a modern IdP (Okta, Ping, JumpCloud, or similar), with Single Sign-On, MFA, and automated lifecycle provisioning.
- Strong working knowledge of endpoint management and security tooling, such as JAMF, Windows MDM, SentinelOne, and vulnerability management platforms.
- Hands-on experience modernizing network environments, including firewalls, switching, wireless, and SD-WAN; experience with cloud-managed, single-pane platforms such as Cisco Meraki is a strong plus.
- Firm grasp of Zero-Trust networking concepts and implementations, including certificate-based Wi-Fi, least-privilege access, and centralized logging.
- Experience implementing or operating a SIEM and supporting security operations and incident response.
- Working knowledge of ITIL operational processes (incident, problem, change, and configuration management) and the ability to lead within a structured operations environment.
- Solid understanding of networking fundamentals including DNS, DHCP, TCP/IP, VPN, and firewall administration.
- Proven track record with endpoint protection, patch management, vulnerability remediation, and disaster recovery, business continuity, and backup strategies.
