• Designing secure access solutions using SSO, MFA, device posture and least-privilege principles.
• Integrating Zero Trust platforms with identity providers such as Entra ID, Okta or Ping, alongside SIEM/SOAR and endpoint security platforms.
• Supporting the migration of legacy VPN, proxy and firewall solutions towards modern cloud-native security models.
• Leading proof-of-concepts, technical validation and security architecture assessments.
• Providing architectural governance, threat modelling and security guidance across client projects.
• Working with senior stakeholders to shape Zero Trust strategies and long-term security roadmaps.

• Good knowledge of IAM, including Entra ID/Azure AD, Okta or Ping.
• Understanding of modern network security, including SD-WAN, DNS security and routing.
• Experience with endpoint security and EDR/XDR technologies.
• Strong communication and stakeholder management skills, with the ability to explain complex security concepts to both technical and non-technical audiences.
• Experience working in large, complex enterprise environments.

What's in it for you

• Hybrid working from London
• 25 days' annual leave
• Private medical insurance
• 3 additional days' leave for charitable work
• Opportunity to work on large-scale Zero Trust and cybersecurity transformation programmes
• Exposure to leading security technologies and enterprise environments
