Grand Bank - Infrastructure Engineer

Continental Finance Company•Hattiesburg, MS

46d•Onsite

About The Position

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. The Infrastructure Engineer is a hands-on, generalist engineering role within the Bank’s small Information Technology department, rather than a specialized position on a larger team. The position carries primary ownership of virtualization, backup and recovery, storage, network and perimeter security, identity, and patch management; provides tier-2 and tier-3 technical escalation; supports business continuity and disaster recovery; and produces the documentation and evidence required in an environment regulated by the Office of the Comptroller of the Currency (OCC) and examined under the Federal Financial Institutions Examination Council (FFIEC) IT Examination Handbook, where every change is documented, approved, and evidenced. The successful candidate must be prepared to serve as the Bank’s primary technical resource for rebuilding hypervisor hosts, tracing firewall rules, and restoring domain controllers, and must exercise sound judgment about operational risk. The position has no direct reports and is classified as exempt. The Infrastructure Engineer reports to the Bank’s Chief Information Officer / Information Security Officer (CIO/ISO).

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.

Working knowledge of enterprise next-generation firewall administration, including security and NAT policy, security profiles, and version upgrades.

Sound judgment about operational risk and change impact, including an understanding that an error affecting core banking or domain controller systems may trigger incident escalation and regulatory notification obligations, and willingness to escalate rather than improvise on critical systems.
Demonstrated ownership, with the ability to take a problem from first report through root cause to documented resolution with limited supervision.
Ability to move effectively between storage, network, security, and endpoint issues and to manage multiple priorities in the same day.
Strong written and verbal communication skills, including the ability to explain technical risk in plain terms to management, the IT & IS Steering Committee, and non-technical staff.
Ability to pass a background check and satisfy bonding requirements applicable to financial institution employment.
