Network Engineer

OMB Bank is looking for a skilled, hands-on Network Engineer to personally implement and maintain our enterprise network infrastructure. This is an individual contributor role — the Network Engineer is expected to directly perform configuration, troubleshooting, and implementation work across all systems rather than delegate it to others.

Responsibilities

• Monitor network performance and availability, troubleshoot issues, conduct capacity planning, and maintain network documentation and configuration standards.

• Monitor AD health, audit logs, and authentication events to detect and remediate anomalies, and manage associated DNS, DHCP, PAM, and banking compliance requirements.
• Administer Microsoft Azure (virtual networks, VMs, Azure AD) and the full Microsoft 365 tenant including Exchange Online, Teams, and SharePoint.
• Administer the bank’s VoIP/PBX system including call routing, voicemail, auto-attendants, and SIP trunks, coordinating with telecom vendors for upgrades and issue resolution.
• Manage secure remote access solutions (SSL VPN, site-to-site VPN, Zero Trust, and MFA) ensuring compliance with banking regulatory and security requirements.
• Manage network security infrastructure (firewalls, IDS/IPS, SIEM, endpoint protection), conduct vulnerability assessments, respond to incidents, and ensure compliance with FFIEC, GLBA, and PCI-DSS.
• Oversee administration and maintenance of IP-based camera and access control systems across all branch locations, ensuring proper data retention, access controls, and policy compliance.
• Implement and test disaster recovery (DR) and business continuity plans (BCP) for network and IT systems.

• Effective time management skills (capable of managing and prioritizing multiple tasks).
• Demonstrated self-motivation; productive, efficient, organized, accurate work output with no supervision while working independently and within a team environment.
• Ability to apply strategic planning, activity coordination, and problem-solving techniques to complex issues of multiple facets and variables in non-standardized situations.
