Network Infrastructure Engineer

Network Infrastructure Engineer at State Street

We are seeking a Network Infrastructure Engineer to design, build, and operate a modern global network based on Versa, Cisco and Arista technologies including SD-WAN, Network Segmentation, Wireless, Client and Vendor Connectivity and Cloud Computing. The engineer will also be responsible for third party connectivity for SD-WAN and IPSec access. This role sits at the intersection of networking and security and is critical to our transition toward Zero Trust and cloud-first architectures. The engineer will work across campus, office, WAN, cloud, and third party access environments within large, globally distributed enterprise environments, integrating SD-WAN, segmentation, and cloud-delivered security controls to deliver resilient, scalable, and secure connectivity. This role plays a key part in evolving the firm’s global network, security and segmentation posture. The engineer will implement standards and architecture decisions across campus, branch, and cloud environments globally.

This role is ideal for an engineer who is strong in one or more of these domains and motivated to deepen their expertise across secure edge, Zero Trust, and modern network architectures.

We value curiosity, adaptability, and sound engineering judgment as much as prior exposure to specific tools or platforms.

What You Will Be Responsible For

Candidates are not expected to have deep expertise in every area listed below. Strength in several of these domains, combined with the ability to learn and adapt, is highly valued.

• Strong routing and switching especially strong BGP and BGP to OSPF routing redistribution.
• SD-WAN technologies and architectures (Versa SD-WAN preferred).
• Network segmentation including VRFs, VLANs, access control, and micro segmentation.
• Designing and supporting enterprise campus networks, including wired and wireless with Cisco and Arista technology.
• Engineering and configuration of IPSec VPNs.
• Configuration and Troubleshooting skills across WAN, LAN, wireless, and secure access domains both with management tools and CLI.
• Experience with Dot1X and Port Level Security deployments.
