IT Manager

The IT Manager of Infrastructure & Security is responsible for leading, managing, and maintaining the organization’s hardware, networks, and core infrastructure systems in a secure, high-availability, and scalable manner. This role focuses exclusively on infrastructure and security (not business software or application development). The person in this role ensures robust, resilient, and secure operations that support all business functions.

• Oversee the design, deployment, and maintenance of all physical and virtual infrastructure, including servers, storage, network devices (switches, routers, firewalls), and datacenter equipment (racks, UPS, cooling)
• Manage procurement, setup, configuration, and lifecycle (installation, maintenance, replacement) of hardware assets
• Ensure redundant and fault-tolerant architecture (failover, clustering, backups)
• Oversee virtualization (e.g., VMware, Hyper-V) and/or containerization infrastructure (if applicable)
• Manage connections to cloud infrastructure (if hybrid environment) or network links (VPNs, WAN links, MPLS, direct circuits)
• Monitor and tune system performance; capacity planning and forecasting
• Coordinate with power, cooling, and facilities teams for data center environment

• Design, implement, and maintain LAN, WAN, wireless, and remote access infrastructure
• Configure and manage network security devices (firewalls, IDS/IPS, VPNs)
• Ensure high availability, resilience, and load balancing of network services
• Monitor network traffic, detect anomalies, address congestion or performance bottlenecks
• Maintain network diagrams, documentation, and change logs

• Define, implement, and enforce infrastructure and network security policies and best practices
• Manage firewall rules, intrusion detection/prevention, vulnerability scanning, security audits, and patch management
• Oversee system hardening and secure baseline configurations for servers, network devices, and hardware
• Lead threat detection, incident response, and forensic investigations when infrastructure is implicated
• Ensure compliance with regulatory or industry security standards (e.g., PCI, HIPAA, GDPR, ISO 27001) as applicable
• Work with external security vendors or auditors on penetration tests, security assessments, and remediation plans

• Develop, manage, and test backup, restore, and disaster recovery strategies (offsite backups, replication)

• Plan and execute infrastructure failover and disaster recovery exercises
• Ensure ongoing data integrity, redundancy, and availability
• Lead and mentor infrastructure / operations staff and contractors
• Collaborate with software and business systems teams to ensure infrastructure meets their needs (even though you don’t own those systems)
• Serve as the escalation point for infrastructure outages, performance issues, or security incidents
• Define budgets, forecasts, and capital expenditures for infrastructure-related investments
• Produce regular reports on infrastructure health, security posture, capacity, and performance

• Set standards for naming conventions, IP schemes, hardware configurations, and standard operating procedures

• Bachelor’s degree in Computer Science, Information Systems, Engineering, or equivalent experience
• 7+ years of experience in IT infrastructure, network, or systems operations
• 3+ years of direct leadership/management experience
• Strong hands-on experience with servers, storage systems, network devices (routers, switches, firewalls), virtualization, and datacenter operations
• Deep knowledge of networking protocols (TCP/IP, OSPF, BGP, VLANs, MPLS, VPNs, etc.)
• Proven experience in infrastructure security, firewalls, IDS/IPS, network segmentation, vulnerability management
• Experience with backup, replication, disaster recovery planning, and…
