  • Document and maintain Azure network diagrams, architecture standards, and routing policies.

ATM Network Management

  • Serve as the primary owner for all ATM network connectivity, hardware, and vendor coordination.
  • Manage vendor and carrier relationships to ensure ATM network reliability, SLAs, and uptime objectives are met.
  • Continuously monitor ATM network performance, latency, and connectivity health.
  • Verify that ATM communication modules, network routers, and circuits remain fully operational.
  • Coordinate and verify hardware maintenance, firmware upgrades, and configuration changes.

Video and Surveillance Systems

  • Own and manage the CCTV video system, including NVR servers, switches, cameras and connectivity.
  • Act as the primary contact for surveillance vendors, overseeing escalations, service calls, and equipment life cycles.
  • Perform routine video system health checks, ensuring camera functionality, recording status, video quality and storage integrity.
  • Coordinate with physical security teams for deployment planning, upgrades, and maintenance.

Network Services & Systems

  • Administer and troubleshoot DHCP, DNS, and Radius authentication systems.
  • Implement and maintain 802.1X network access control (NAC) across wired and wireless environments, ensuring only authorized devices gain network access.
  • Support secure onboarding for corporate and IoT devices using Radius policies and certificate-based authentication.
  • Manage UPS, PDU, and management systems to ensure power reliability and environmental visibility across network infrastructure.

Monitoring & Performance

  • Utilize PRTG Network Monitor for proactive monitoring, performance analysis, and alert response across all infrastructure and cloud resources.
  • Develop and maintain dashboards and alerting systems to identify and resolve issues before they impact operations.
  • Conduct capacity planning and trend analysis to ensure optimal network performance.
  • Educate and instruct system and security engineers on the capabilities of the monitoring systems.
  • Continually evaluate the system and offer suggestions for additional monitoring needs.

Documentation & Compliance

  • Maintain comprehensive network diagrams, inventories, and configuration documentation.
  • Champion Change management and ticketing processes for the organization.
  • Ensure compliance with internal IT standards, audit requirements, and industry security frameworks.
  • Participate in disaster recovery testing, documentation, and network resiliency planning.

  • Strong hands-on experience with corporate networking technologies (Wireless, switching, SDWAN, routing and firewalls)
  • Proven experience managing vendor relationships.
  • Proficiency with Azure networking, including VNets, routing, ExpressRoute, NSGs, and hybrid architectures.

  • Experience working in financial institutions or other regulated environments supporting ATMs and video systems.

Competencies

  • Strong sense of ownership and accountability for network uptime and reliability.
  • Deep understanding of hybrid (on-prem + Azure) network architecture.
