Senior Zero Trust Network Access (ZTNA) Engineer

Experience Level: 3-5 Years

Role Type: Full-Time

Role Overview

We are seeking a Senior Zero Trust Network Access (ZTNA) Engineer to architect, deploy, and manage our modern identity-centric perimeter security solutions. Spanning the complete service delivery lifecycle-Assess, Build, Transition, and Operations-this role is pivotal in replacing legacy VPN architectures with least-privilege, context-aware access controls. The ideal candidate will have hands-on experience integrating ZTNA platforms with enterprise Identity Providers (IdP), enforcing device posture checks, and securing hybrid enterprise applications.

Key Responsibilities

Assess (Architecture Review Posture Analysis)

• Conduct comprehensive audits of existing remote access models, legacy VPN concentrators, and internal application exposure.
• Analyze user access patterns, application dependencies, and data flows to map out micro-segmentation and least-privilege policies.
• Evaluate current Identity Provider (IdP) readiness, multi-factor authentication (MFA) enforcement, and endpoint device posture compliance mechanisms.

Build (Deployment Policy Engineering)

• Deploy, configure, and manage enterprise ZTNA solutions (e.g., Zscaler ZPA, Palo Alto Prisma Access, Cloudflare One, or Cisco Secure Access).
• Design and implement context-aware access policies combining user identity, device health, location, and risk scores.
• Provision and configure ZTNA connectors (gateways/brokers) across on-premise data centers, AWS, Azure, and GCP environments.
• Integrate ZTNA platforms with enterprise Single Sign-On (SSO) and Directory Services (e.g., Entra ID/Azure AD, Okta).

Transition (Migration, Testing Handover)

• Drive the phased migration roadmap from legacy VPN solutions to ZTNA with minimal disruption to business units.
• Coordinate User Acceptance Testing (UAT) with business application owners to validate seamless context-based access.
• Develop "As-Built" architecture diagrams, policy migration runbooks, and troubleshooting guides for support desks.
• Conduct enablement sessions for IT helpdesks and operations teams on ZTNA client troubleshooting and policy management.

Operations Continuous Management

• Serve as the senior escalation point for complex ZTNA connectivity, identity assertion, and connector health issues.
• Perform continuous policy lifecycle management, reviewing access rules, removing stale policies, and refining posture checks.
• Monitor ZTNA tunnel performance, broker throughput, and client app stability across global endpoints.
• Ensure real-time security telemetry and access logs stream successfully into the SIEM for threat hunting and compliance monitoring.
• Understanding of ITIL-based Change Management, managing end-to-end change lifecycle activities, CAB coordination, and compliant implementation of infrastructure and application changes

Required Skills Qualifications

• Experience: 3-5 years of dedicated experience in network security, identity and access management (IAM), or zero trust architecture implementation.
• Core Technologies: Hands-on expertise with market-leading ZTNA platforms (e.g., Zscaler Private Access, Palo Alto Prisma Access, Cloudflare One, or Microsoft Global Secure Access).
• Identity Networking: Strong grasp of IAM principles, SAML/OIDC authentication protocols, Active Directory/Entra ID, and foundational networking (DNS, TCP/IP, routing, firewalls).
• Zero Trust Principles: Deep understanding of "Never Trust, Always Verify" paradigms, micro-segmentation, and device posture validation frameworks.
• Certifications: Relevant vendor or cloud security certifications (e.g., Zscaler Certified Cloud Security Professional, PCNSE, AWS/Azure Security, or CISSP/CCSP) are highly preferred.
• Soft Skills: Strong cross-functional collaboration skills, ability to manage enterprise-wide change initiatives, and excellent technical documentation capabilities.
