We are seeking a Senior Zscaler Network Engineer to enhance our current Zscaler rollout capacity and strengthen day-to-day operational support. This role will focus on Zscaler Internet Access (ZIA), Zscaler Private Access (ZPA), and their integration with Palo Alto firewalls, Cisco networking, and Okta.
The engineer will work closely with an existing Principal Network Engineer (FTE) and the broader network/security teams to:
Scale and optimize our ZIA and ZPA deployments
Troubleshoot complex, day-to-day Zscaler and network issues
Own technical intake and assessment for new Zscaler-related projects from internal organizations
Mentor and upskill other team members on Zscaler and related network and identity technologies
The ideal candidate is Zscaler-certified, highly hands-on, and comfortable in a fast-paced enterprise environment. The position is hybrid, with approximately half of the time spent onsite at our Pleasanton, CA HQ and half working remotely.
Key Responsibilities -
Zscaler Rollout & Implementation (ZIA / ZPA):
Execute and enhance the rollout of ZIA and ZPA for users, sites, and applications in partnership with the Principal Network Engineer (FTE).

Contribute to implementation plans, change requests, and repeatable runbooks to ensure consistent, high-quality deployments.
Integration with Palo Alto, Cisco, and Okta
Integrate and optimize Zscaler with Palo Alto firewalls and Cisco network infrastructure (routing, switching, SD-WAN/VPN) for secure internet egress and private access.
Implement and maintain Okta integration for authentication, SSO, and user/group-based policy enforcement in Zscaler.
Work with security and identity teams to align policies across Zscaler, Palo Alto, Cisco, and Okta.
Day-to-Day Operations & Troubleshooting:
Serve as a Senior escalation point for Zscaler-related incidents and requests.
Perform detailed troubleshooting across endpoints, Cisco network paths, Palo Alto firewalls, Zscaler (ZIA/ZPA), and applications to resolve connectivity, performance, and policy issues.
Collaborate with internal teams and vendors to drive issues to root cause and permanent remediation.
Improve monitoring, logging, and alerting for ZIA and ZPA, leveraging existing tools and SIEM integrations.
Project Intake & Delivery:
Act as a technical contact for new project intake where Zscaler is a dependency (e.g., onboarding new applications to ZPA, new sites or user groups to ZIA, or new security requirements).
Assess requirements from internal teams, identify Zscaler, Palo Alto, Cisco, and Okta impacts, and propose appropriate technical designs and implementation approaches.
Provide effort estimates, dependencies, and clear technical tasks to support project planning and execution.
Mentoring & Team Enablement:
Mentor and coach other network and security engineers on ZIA, ZPA, Palo Alto, Cisco, and Okta integrations.
Share best practices through documentation, knowledge-transfer sessions, and active participation in design and review discussions.
Help standardize operational procedures, troubleshooting playbooks, and checklists for the broader team.
