Summary
The IT Manager of Infrastructure & Security is responsible for leading, managing, and maintaining the organizations 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.
Key Responsibilities
- 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
Network & Connectivity
Design, implement, and maintain LAN, WAN, wireless, and remote access infrastructureConfigure and manage network security devices (firewalls, IDS / IPS, VPNs)Ensure high availability, resilience, and load balancing of network servicesMonitor network traffic, detect anomalies, address congestion or performance bottlenecksMaintain network diagrams, documentation, and change logsSecurity & Compliance
Define, implement, and enforce infrastructure and network security policies and best practicesManage firewall rules, intrusion detection / prevention, vulnerability scanning, security audits, and patch managementOversee system hardening and secure baseline configurations for servers, network devices, and hardwareLead threat detection, incident response, and forensic investigations when infrastructure is implicatedEnsure compliance with regulatory or industry security standards (e.g., PCI, HIPAA, GDPR, ISO 27001) as applicableWork with external security vendors or auditors on penetration tests, security assessments, and remediation plansBackup, Disaster Recovery & Business Continuity
Develop, manage, and test backup, restore, and disaster recovery strategies (offsite backups, replication)Establish and validate recovery time objectives (RTO) and recovery point objectives (RPO)Plan and execute infrastructure failover and disaster recovery exercisesEnsure ongoing data integrity, redundancy, and availabilityLeadership & Collaboration
Lead and mentor infrastructure / operations staff and contractorsCollaborate 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 incidentsMaintain vendor relationships (hardware vendors, network providers, security tool vendors)Define budgets, forecasts, and capital expenditures for infrastructure-related investmentsProduce regular reports on infrastructure health, security posture, capacity, and performanceDocumentation & Standards
Maintain up-to-date documentation (network diagrams, infrastructure inventories, configurations, troubleshooting guides)Define and enforce infrastructure change control, patch, and maintenance windowsSet standards for naming conventions, IP schemes, hardware configurations, and standard operating proceduresRequired
Qualifications & Experience
Bachelor???s degree in Computer Science, Information Systems, Engineering, or equivalent experience7+ years of experience in IT infrastructure, network, or systems operations3+ years of direct leadership / management experienceStrong hands-on experience with servers, storage systems, network devices (routers, switches, firewalls), virtualization, and datacenter operationsDeep knowledge of networking protocols (TCP / IP, OSPF, BGP, VLANs, MPLS, VPNs, etc.)Proven experience in infrastructure security, firewalls, IDS / IPS, network segmentation, vulnerability managementExperience with backup, replication, disaster recovery planning, and executionFamiliarity with cloud connectivity or hybrid infrastructure setupsStrong analytical, troubleshooting, and problem-solving skillsExcellent communication skills (verbal, written) and ability to interface with non-technical leadershipPreferred
Certifications such as CISSP, CISM, CCNP / CCIE, VMware VCP, or similarExperience with infrastructure as code, automation tools (Ansible, Terraform)Prior experience operating in regulated industries or compliance frameworksExperience with hybrid or multi-cloud setupsExperience with monitoring, alerting, logging (e.g. Nagios, Zabbix, Prometheus, ELK, Splunk)Key Performance Indicators (KPIs) / Metrics
