Position Summary: The Infrastructure Engineer is responsible for the day-to-day operation, maintenance, and security of the technology infrastructure that supports Grand Bank for Savings, FSB (the “Bank”). The position administers the Bank’s primary and secondary data centers, the Windows Server virtual machine environment, the storage and backup platforms beneath them, and the network and firewall layer connecting them.

Maintain build standards and hardening baselines for current Windows Server releases and manage the server lifecycle from provisioning through decommission. Backup, Replication, and Recovery Administer Veeam Backup & Replication, including job design, scale-out backup repository health, cloud capacity tier offload, and replication between the primary and secondary data centers. Perform and document automated restore verification and produce restore evidence for internal audit and regulatory examiners. Maintain and test the technical recovery procedures supporting the Bank’s business continuity and disaster recovery plans. Storage Administer the shared storage area network (SAN) at both data centers, including LUN and volume provisioning, multipathing, firmware currency, capacity forecasting, and performance troubleshooting. Coordinate storage vendor support cases and hardware replacements. Network and Perimeter Security Administer enterprise next-generation firewalls, including security and NAT policy, security profiles, OS upgrades, remote-access virtual private network (VPN), and log forwarding to the security information and event management (SIEM) platform. Administer cloud-managed enterprise switching and wireless, including VLAN and port configuration, SSID and wireless policy, firmware management, and dashboard alerting. Maintain accurate network documentation, including VLAN assignments, zone definitions, and segmentation diagrams, to the standard expected by auditors and examiners.

Operate the endpoint and server patch management program on an enterprise patch management platform, including deployment rings, compliance reporting, failure triage, and exception documentation. Support vulnerability remediation driven by scanner findings and act on SIEM alerts in coordination with the CIO/ISO.

At least 5 years of experience administering Windows Server infrastructure in a production environment, including at least 3 years with primary ownership of virtualization, backup, and network administration. Demonstrated experience as a generalist infrastructure engineer in a small IT organization, or equivalent evidence of independent end-to-end ownership. Production administration experience with VMware vSphere, including vCenter Server, ESXi, clustering, vMotion, and host maintenance. Working knowledge of current versions of Veeam Backup & Replication, including job configuration, repositories, replication, and restore execution. Experience with shared SAN administration (iSCSI or Fibre Channel), LUN provisioning, and multipath troubleshooting. Working knowledge of enterprise next-generation firewall administration, including security and NAT policy, security profiles, and version upgrades. Experience with cloud-managed switching and wireless administration, VLAN and trunk configuration, and wireless SSID policy.
