Oversee the design, implementation and administration of network infrastructure (LAN/WAN, switches, routers, VLANs) and connectivity solutions to ensure secure, scalable and high-performance communication across sites.
Administer and maintain server infrastructure (Windows Server, Linux distributions), virtualization platforms (VMware, Hyper-V), and containerization where applicable, ensuring optimal performance, patching and capacity planning.
Operate and optimize identity and access management systems (Active Directory, Azure AD, Single Sign-On) and maintain secure authentication/authorization policies for users and services.
Direct endpoint management and security (SCCM, Intune, JAMF, antivirus/EDR) including OS deployment, patching, configuration standards, and device lifecycle management for desktops, laptops and mobile devices.
Oversee cloud services administration (Azure, AWS) and hybrid architectures, including cost optimization, instance sizing, security groups, IAM, and cloud backup/DR procedures.
Enforce cybersecurity best practices: manage firewalls, VPNs, IDS/IPS, encryption standards, vulnerability scanning, regular patch cycles and coordinate incident response and forensic investigation as needed.
Manage backup, disaster recovery and business continuity plans (Veeam, native cloud backups) and conduct periodic DR testing, documentation updates and remediation planning.
Supervise the IT helpdesk and ticketing processes (ServiceNow, Jira Service Desk, Zendesk), set SLA/KPI targets, triage escalations, ensure timely resolution, and continuously improve knowledge base and support workflows.
Lead IT projects from requirements gathering to implementation and post-implementation review — including network upgrades, system migrations, Office 365/Microsoft 365 rollouts, VoIP deployments and hardware refreshes — using appropriate project governance (Agile/Waterfall).
Maintain IT asset and license management: track hardware inventory, software licensing compliance, procurement cycles, warranty and vendor renewals while optimizing TCO.
Coordinate vendor and third-party relationships: negotiate contracts, manage SLAs, evaluate vendor performance, and escalate procurement issues to procurement or finance when required.
Establish and continually refine IT policies, standard operating procedures and change management processes to minimize operational risk and ensure audit readiness and regulatory compliance (PCI, HIPAA, SOX as applicable).
Monitor IT performance metrics, produce executive and operational reports (uptime, ticket trends, patch compliance, security posture), and present improvement plans to leadership.
Execute cost control and budgeting activities for infrastructure, software, cloud spend and services, and provide forecasts and variance reports to finance and senior management.
Drive operational automation initiatives (scripting in PowerShell, Python, Ansible) to reduce repetitive tasks, speed provisioning and improve consistency across environments.
Ensure secure configuration and lifecycle of network security appliances (Cisco, Fortinet, Palo Alto), including firmware updates, rule reviews, change control and logging/alerting.
Provide technical oversight and support for collaboration and productivity platforms (Office 365/Microsoft 365, Teams, Exchange, SharePoint) including migrations, mail hygiene and retention policies.
Lead security awareness, end-user training programs and runbooks for standard procedures, phishing simulations and onboarding/offboarding processes to reduce human risk and accelerate new-hire readiness.
Manage physical infrastructure aspects such as datacenter/rack organization, power/cooling, cabling standards, on-site vendor coordination and remote site connectivity.
Coordinate with legal, HR and compliance teams for data protection matters, access reviews, and audit support requests, ensuring timely and accurate evidence collection.
Drive continuous improvement through root cause analysis for major incidents, postmortem documentation, corrective action plans and knowledge sharing across IT and business teams.
Oversee configuration management and maintain accurate, versioned documentation for networks, servers, applications, runbooks and escalation contacts to ensure business continuity.
Participate in strategic IT roadmaps and solution architecture discussions to align infrastructure projects with business growth, digital transformation and security priorities.
