We are looking for an experienced Zero Trust Security Architect to design, implement and optimise enterprise-scale Zero Trust security architectures.

Youll work across users, devices, applications and data, helping organisations modernise their security through cloud-first, identity-centric and SASE-based approaches. The role offers hands-on exposure to leading Zero Trust technologies, including Zscaler, while working with cross-functional security, networking and infrastructure teams.

Key Responsibilities
  • Design and implement enterprise Zero Trust architectures aligned to NIST 800-207 and CISA principles.
  • Develop secure access models using Zscaler ZIA, ZPA, ZDX and Client Connector.
  • Design identity-centric controls covering SSO, MFA, device posture and least privilege.
  • Deploy and optimise technologies including DLP, CASB, FWaaS, Cloud Firewall and App Connectors.
  • Integrate Zero Trust platforms with Entra ID, Okta, SIEM/SOAR and endpoint security platforms.
  • Support migration from legacy VPN, proxy and firewall technologies to modern Zero Trust models.
  • Conduct POCs, technical validation, threat modelling and security gap assessments.
  • Troubleshoot and optimise Zero Trust deployments, telemetry and access controls.
  • Provide technical guidance, mentorship and architectural governance.
Key Requirements
  • 510+ years experience in cybersecurity architecture or senior engineering roles.
  • Strong hands-on experience with Zscaler ZIA, ZPA, ZDX and Client Connector or similar Zero Trust technologies.
  • Experience with App Connectors, Cloud Firewall, Cloud Sandbox, DLP and CASB.
  • Strong understanding of Zero Trust, NIST 800-207, SASE and SSE.
  • Knowledge of IAM, Entra ID/Azure AD, Okta or Ping.
  • Understanding of SD-WAN, DNS security, routing and endpoint security/EDR/XDR.
  • Strong communication and stakeholder management skills.
  • Ability to explain complex security concepts to technical and non-technical audiences.
  • Experience working in large, matrixed enterprise environments.
Desirable Certifications
  • Zscaler certifications such as ZCCA-IA, ZCCA-PA or ZCCP.
  • CISSP, CCSP or equivalent.
  • Azure, AWS or GCP cloud certifications.
  • SASE/SSE certifications such as Palo Alto Prisma or Netskope.
  • CCNA or equivalent networking certification.
