Description

IT Manager

IT Manager Summary: 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. 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 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

Security & Compliance

• 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

Backup, 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 exercises
• Ensure ongoing data integrity, redundancy, and availability

Leadership & Collaboration

• 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
• Maintain vendor relationships (hardware vendors, network providers, security tool vendors)
• Define budgets, forecasts, and capital expenditures for infrastructure-related investments
• Produce regular reports on infrastructure health, security posture, capacity, and performance

Documentation & Standards

• Maintain up-to-date documentation (network diagrams, infrastructure inventories, configurations, troubleshooting guides)
• Define and enforce infrastructure change control, patch, and maintenance windows
• Set standards for naming conventions, IP schemes, hardware configurations, and standard operating procedures

Qualifications & Experience Required

• 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 execution
• Familiarity with cloud connectivity or hybrid infrastructure setups
• Strong analytical, troubleshooting, and problem-solving skills
• Excellent communication skills (verbal, written) and ability to interface with non-technical leadership

Preferred

• Certifications such as CISSP, CISM, CCNP / CCIE, VMware VCP, or similar
• Experience with infrastructure as code, automation tools (Ansible, Terraform)
• Prior experience operating in regulated industries or compliance frameworks
• Experience with hybrid or multi-cloud setups
• Experience with monitoring, alerting, logging (e.g. Nagios, Zabbix, Prometheus, ELK, Splunk)

Key Performance Indicators (KPIs) / Metrics

• Infrastructure uptime / availability (percentage)
• Mean time to restore (MTTR) for outages
• Number / severity of security incidents tied to infrastructure
• Patch compliance / vulnerability remediation metrics
• Capacity utilization vs headroom
• Number of successful DR test recoveries
• Infrastructure costs vs budget

Working Conditions

• May require occasional off-hours or weekend support for planned maintenance or emergency issues
• May require physical presence in data centers or server rooms
• On-call rotation for critical infrastructure support
