Zero Trust Security Architect - London

How to design, implement, and optimise enterprise-scale Zero Trust security architectures. You will gain hands-on experience with leading Zero Trust platforms such as Zscaler and develop a strong understanding of modern identity-centric, cloud-first security models. Working alongside cross-functional teams, you will help to shape secure architectures, define strategic roadmaps, and support secure transformation across networks, applications, and endpoints.

• Leading the design and implementation of Zero Trust architectures for enterprise environments, covering users, devices, applications, and data.
• Establishing secure access patterns using cloud-based security and zero-trust platforms (e.g., Zscaler ZIA, ZPA, ZDX)
• Creating enterprise-wide security blueprints and reference architectures aligned with Zero Trust principles (NIST 800-207, CISA).
• Designing scalable identity-centric security controls using SSO, MFA, device posture, and least-privilege access models.
• Collaborating with networking teams to modernize WAN and remote access using cloud security and SASE frameworks.

• Deploying, configuring, and optimising Zero Trust technologies, including:
• Policy creation and fine-tuning (e.g., URL filtering, DLP, CASB, FWaaS).
• Managing App segmentation and connector deployment.
• Zero Trust Client Connector configuration and rollout.
• Integrating Zero Trust solutions with identity providers (Entra AD, Okta), SIEM/SOAR systems, and endpoint platforms such as CrowdStrike etc.
• Collaborating with infrastructure teams to migrate legacy VPN, proxy, and firewall solutions to cloud native Zero Trust models.
• Conducting proof-of-concept evaluations and technical validation sessions.

• Driving the organization’s Zero Trust strategy and security roadmap.
• Providing architectural governance and ensuring security best practices across projects.
• Conducting threat modelling, gap assessments, and risk evaluations for critical applications and network paths.
• Advocate for the adoption of modern security frameworks and secure-by-design principles.

• Troubleshooting Zero Trust deployment issues, performance concerns, and identity-related access failures.
• Monitoring and tuning telemetry, logs, and analytics to maintain optimal operational performance.
• Providing technical mentorship and training to internal security and networking teams.

• 5–10+ years of experience in cybersecurity architecture or senior engineering roles.
• Strong hands-on expertise with:
• Zscaler ZIA, ZPA, ZDX or similar
• Zscaler Client Connector
• App Connectors, Cloud Firewall, Cloud Sandbox, DLP, CASB
• Deep understanding of:
• Zero Trust frameworks (NIST 800-207, SASE, SSE)
• Identity and access management (Azure AD, Okta, Ping)
• Modern network design (SD-WAN, DNS security, routing fundamentals)
• Endpoint security (EDR/XDR, device posture assessment)

• Strong communication and stakeholder management skills.
• Ability to translate complex security concepts into business-friendly language.
• Experience working within large, matrixed enterprises.
• Proven ability to lead cross-functional initiatives.

By showcasing the following:

• Zscaler Certification (ZCCA-IA, ZCCA-PA, ZCCP)
• CISSP, CCSP, or similar security credentials
• Cloud certifications in Azure, AWS, GCP (highley desirable)
• Certifications form other leading SASE/SSE vendors, such as Palo Alto Prisma, Netskope are advantageous
• Network certification such as CCNA or equivalent
