Original job description

Description SUMMARY The Network, Security & Cloud Infrastructure Manager partners with the Director of Technology to ensure the performance, resiliency, and security of the School's network, cloud, identity, virtualization, cybersecurity, and enterprise systems. This senior-level, hands-on role advances cybersecurity, disaster recovery, business continuity, and cloud infrastructure while providing front-line support, serving as an escalation point for complex issues, and establishing the standards, governance, and guardrails that enable faculty, staff, and students to innovate safely with cloud services, artificial intelligence, automation, and software development.

This is a full-time, 12-month, exempt-level position. Most work takes place during normal school hours, with after-hours support required during maintenance windows, infrastructure emergencies, and cybersecurity incidents.

IN THIS ROLE, YOU WILL…

Administer, maintain, and modernize the School’s wired and wireless network, Cisco Meraki security infrastructure, Proxmox virtualization, Windows and Linux servers, enterprise storage, and related systems. Monitor performance, capacity, availability, patching, and lifecycle; maintain architecture documentation; recommend upgrades and modernization initiatives; and provide hands-on support for complex infrastructure issues.
Design, implement, and govern Microsoft Azure infrastructure and services, including standards for secure cloud provisioning, resource utilization, lifecycle management, and appropriate use of cloud services.
Serve as a senior, hands-on member of the cybersecurity team and a primary contact for cybersecurity incidents. Lead threat detection, hunting, triage, containment, remediation, and post-incident review; coordinate vulnerability assessments and penetration testing; and administer Microsoft Defender, Red Canary, and related security controls protecting systems, data, identities, and infrastructure.
Develop, maintain, monitor, and regularly validate on-premises and cloud backup, recovery, and disaster-recovery processes, and collaborate with the Director of Technology on business continuity and organizational resilience.
Establish and govern secure development environments, source-code repositories, application hosting, authentication, secrets, APIs, cloud resources, and deployment workflows for faculty, staff, and student software-development initiatives.
Establish secure deployment standards and maintain governance for internally developed applications, including ownership, privacy, security, supportability, lifecycle, and retirement requirements.
Help evaluate and govern emerging technologies, including generative AI; establish standards and guardrails for AI-assisted software development, AI coding assistants, application-development tools, and cloud-based AI services.
Lead infrastructure, cybersecurity, cloud, and modernization projects; develop technical standards, policies, procedures, and documentation; and evaluate vendors, managed services, products, and solutions aligned with organizational goals.

Requirements

A SUCCESSFUL CANDIDATE HAS…

A bachelor's degree in a technology-related field and at least 8 years of related work experience.
Deep, hands-on experience with Cisco Meraki firewalls, switching, wireless networks, and security services; extensive experience with Proxmox, VMware, Hyper-V, Windows and Linux servers, storage, patch management, and infrastructure troubleshooting.
Demonstrated ability to investigate, hunt, detect, triage, contain, and remediate threats, with practical experience using advanced security products such as Microsoft Defender, Red Canary, SentinelOne, Arctic Wolf, or FireEye.
Strong knowledge of the Microsoft 365 ecosystem across cloud and on-premises environments, including Azure, Entra ID, Intune, Active Directory, DNS, Windows, Microsoft Defender, Microsoft Purview, and related identity and data-protection services.
Current experience with cybersecurity frameworks, risk management, security monitoring, data protection, backup, disaster recovery, business continuity, and cloud-based solutions such as Azure or AWS.
Strong troubleshooting, project-management, documentation, analytical, written, and verbal communication skills, with the ability to work independently, prioritize complex work, manage multiple assignments, and make decisions within a budget process.
A collaborative, security-first mindset that enables innovation and creativity; a commitment to unmatched customer service, confidentiality, teamwork, and building standards, processes, and guardrails for long-term organizational success.
Preferred experience in K-12, higher education, or nonprofit environments; Microsoft Sentinel, SIEM and incident-response tooling; Azure App Services, Functions, SQL, and cloud-native hosting; GitHub administration; vulnerability and penetration testing; AI governance; and PowerShell, Python, or similar automation languages.
Preferred certifications such as CCNA, Cisco Meraki Solutions Specialist, Microsoft Azure Administrator Associate, Azure Security Engineer Associate, Cybersecurity Architect Expert, CISSP, CompTIA Security+, or Network+.

PHYSICAL REQUIREMENTS AND WORK ENVIRONMENT

Works primarily in an office or classroom environment, with frequent interaction with faculty, staff, students, parents, and alumni.
Most work occurs during normal school hours with some flexibility in start and end times; light travel for professional development is possible.
Regularly sits for long periods and works at a desk and computer.
Ability to walk up to 2 to 3 miles in a day around campus and to occasionally lift equipment weighing 50 to 75 lbs.
Ability to maintain appropriate professional boundaries with students, fellow staff, and all community members.
