- Lead design and implementation of ZTNA solutions (Zscaler ZPA/ZIA, ZVPN) to replace legacy VPN technologies
- On call required rotation
- Define and deliver modern Zero Trust architecture patterns, including application-level segmentation and identity-based access
- Drive legacy VPN decommissioning and migration to ZTNA platforms
- Develop and execute engineering roadmaps aligned to enterprise remote access strategy
- Partner with security, infrastructure, and business units to ensure coordinated rollout and adoption
- Document architecture, operational models, and implementation standards
- Evaluate emerging ZTNA and secure access technologies and provide data-driven recommendations
- Lead pilots and phased deployments, including testing, validation, and performance benchmarking
- Act as a Tier-3 escalation lead for complex remote access and connectivity issues
- Ensure high availability and resilience of remote access infrastructure in a 24x7 global environment
- Assess and mitigate risks related to latency, scale, and user experience during migrations
The Expertise and Skills You Bring
- 6-10 years of network/security engineering experience, including 4+ years in ZTNA or remote access transformations
- Bachelor's degree in Computer Science, Information Technology, or related field
- Hands-on experience with Zscaler (ZPA/ZIA) or comparable Zero Trust platforms
- Proven success migrating legacy VPNs to Zero Trust, cloud-delivered access solutions
- Deep expertise in ZTNA design, implementation, and Zero Trust principles (least privilege, continuous verification, no implicit trust)
- Experience designing application segmentation and identity-based access policies
- Strong knowledge of traffic steering, split tunneling, and secure access routing (ZVPN architectures)
- Experience with load balancing, gateways, and access control layers
- Advanced troubleshooting across network layers (L3-L7)
- Familiarity with hybrid environments (on-prem, cloud, SaaS)
- Ability to optimize latency, performance, and user experience in ZTNA environments
- Experience with high availability, disaster recovery, and failover strategies in global, always-on environments
- Experience with network automation tools (Python, Ansible, APIs)
- Familiarity with endpoint management and deployment tools (Intune, SCCM)
- Strong understanding of identity providers (Azure AD / Entra ID), SSO, and conditional access
- Knowledge of PKI, certificates, and modern authentication methods
- Experience integrating with SIEM, EDR, and security monitoring platforms
- Strong ownership mindset with a focus on execution and delivery
- Ability to thrive in fast-paced, ambiguous environments with competing priorities
- Excellent communication skills across technical and business stakeholders
- Proven ability to lead incident response and drive resolution under pressure
- Preferred certifications: Zscaler (ZCCA / ZCCP / ZCSE), CCNP/CCIE (Security or Enterprise), CISSP (or equivalent), ITIL Foundation
The Team
You will be part of the Enterprise Cloud, Infrastructure, and Operations (ECIO) organization, playing a central role in transforming the enterprise's remote access strategy from legacy VPN to Zero Trust. This is a high-visibility, high-impact team focused on ZVPN rollout and enterprise-wide adoption, legacy VPN decommissioning, and Zscaler-driven Zero Trust transformation.
The team operates in a global, 24x7 environment and partners closely with security, infrastructure, and business stakeholders. Together, you enable secure, seamless access to applications for a distributed workforce-reducing cyber risk, improving resilience, and supporting business continuity at scale.
