Key Responsibilities & Duties:
Infrastructure & Cloud Operations Manage and support IT infrastructure across on-premises, Microsoft Azure, DEEM Cloud, and hybrid cloud environments. Monitor the availability, performance, and capacity of infrastructure services and address technical issues affecting service continuity. Support data center infrastructure, servers, backup solutions, and related technology services. Maintain secure configurations and technical hardening standards across infrastructure components.
Network & Connectivity Manage enterprise network infrastructure, including routers, switches, VLANs, MPLS, WAN connectivity, and Wi-Fi environments. Monitor network performance and availability and troubleshoot connectivity and infrastructure issues. Maintain secure connectivity between on-premises environments, cloud platforms, internet services, and external service providers. Support unified communications and voice services, including Cisco Call Manager, voice gateways, and SIP connectivity, as required.
Infrastructure & Systems Security Implement and maintain security controls across networks, servers, endpoints, databases, cloud environments, and digital services. Manage infrastructure security solutions, including firewalls, VPN, web proxy, endpoint protection, and secure remote access. Monitor security events and alerts through relevant monitoring platforms and investigate incidents based on their technical impact and priority. Support incident containment, service recovery, and improvement of security monitoring controls.
Access, Vulnerability & Security Management Manage and review user, system, and application access controls in accordance with approved security policies and least-privilege principles. Support multi-factor authentication and other access protection mechanisms across relevant systems and services. Analyze vulnerability assessment results and coordinate remediation and security patching activities. Verify the completion and effectiveness of security updates, technical hardening, and corrective actions.
Business Continuity & Disaster Recovery Support backup, restore, high-availability, and disaster recovery capabilities for critical IT services. Execute and participate in disaster recovery, failover, and service restoration tests. Verify the readiness and recoverability of critical systems across DEEM Cloud and data center environments. Identify technical risks affecting infrastructure availability and support appropriate mitigation actions.
Technical Projects, Readiness & Coordination Support infrastructure implementation, upgrades, and technical projects in coordination with internal teams, contractors, vendors, and service providers. Review infrastructure and security readiness before new systems and services are moved into production. Validate that security controls do not adversely affect system performance, connectivity, or service availability. Coordinate technical requirements and follow up on infrastructure-related issues with technology vendors and service providers.
Reporting & Continuous Improvement Prepare periodic operational reports covering infrastructure availability, security incidents, vulnerabilities, risks, and remediation progress. Monitor technical and security performance indicators and identify recurring issues and improvement opportunities. Maintain technical and security documentation to support operational continuity, audit requirements, and future improvements. Recommend practical improvements to infrastructure, security controls, monitoring tools, and operational processes.
