•    Implement and manage firewall rules, policies, and network segmentation to support secure connectivity between bank locations, data center, and vendor environments.

•    Perform rack-and-stack installation of network hardware, along with cabling, patching, and labeling in data center and office network closets.

•    Troubleshoot connectivity and performance issues and support cutover activities, which may include occasional off-hours work.

•    Create and maintain network documentation, including diagrams, IP schemas, patching records, and change documentation.

•    Adhere to the bank’s change management, information security, and compliance standards.

•    3–7 years of hands-on network engineering experience.

•    Basic networking certification (e.g., CCNA, CompTIA Network+, or equivalent).

•    Strong working experience with routing and switching.

•    Experience configuring and managing firewalls (e.g., Palo Alto, Fortinet, Cisco ASA/FTD, or similar).

•    Hands-on physical infrastructure experience, including rack and stack, cabling, and patching.

•    Proven experience with network remediation and troubleshooting.

•    Ability to work onsite 3 days per week at either the New Canaan or Hamden, CT office.

•    Strong documentation habits and clear communication with technical and non-technical stakeholders.

•    Experience in a banking or financial services environment.

•    Prior involvement in a core banking conversion, ideally Jack Henry.

•    Familiarity with security and regulatory expectations for financial institutions.

•    Exposure to VPN, SD-WAN, and wireless technologies.

•    Advanced or vendor-specific certifications (e.g., CCNP, PCNSA/PCNSE, NSE).
