Network Infrastructure Engineer , Assistant Vice President

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.
