The Zscaler Engineer will support the design, implementation, production deployment, and operational transition of a
Zscaler Private Access (ZPA)environment as part of an enterprise identity and secure access modernization initiative. The role will focus on replacing legacy VPN and site-to-site tunnel access with a scalable, Zero Trust–aligned access architecture supporting a large, distributed population of external users and organizations. The initial environment is expected to support approximately
16,600 external users across roughly 1,600 independent agencies
, with the architecture designed to accommodate future expansion to the internal workforce.

The engineer will be responsible for translating a validated proof-of-value architecture into a secure production environment, including ZPA tenant configuration, App Connector architecture, application segmentation, access policies, Client Connector and Browser Access strategies, DNS design, identity integration, logging, migration planning, documentation, and knowledge transfer. The position will work closely with cybersecurity, identity, networking, application, helpdesk, and agency stakeholders throughout implementation and rollout.
