Principal Enterprise Security Architect, Senior Associate (UK)

Intelance is an independent UK advisory firm working across enterprise architecture, cyber security and technology assurance.

We support complex and regulated organisations that need independent, evidence-based decisions about security risk and system design.

We are appointing a small number of Principal Enterprise Security Architects to our associate panel.

This is not permanent employment. Assignments will be offered according to client demand, suitability and availability. There is no guaranteed volume of work.

Tasks

You may be asked to

• Lead independent security architecture reviews for complex enterprise environments.
• Assess cloud, on-premises and hybrid architectures across identity, networks, endpoints, applications, platforms and data.
• Review security requirements, architecture decisions, trust boundaries and control designs.
• Carry out threat modelling and identify credible attack paths and design weaknesses.
• Assess identity and access management, network segmentation, encryption, logging, resilience and recovery arrangements.
• Judge whether proposed alternative controls provide equivalent protection.
• Review high-level and detailed designs and challenge unsupported assumptions.
• Work alongside governance and risk advisors, enterprise architects and technical assessors.
• Turn technical findings into clear decisions and recommendations for executives and boards.
• Produce client-ready architecture findings, diagrams and assurance reports.
• Complete scheme‑specific training and participate in internal quality reviews where required.

Requirements

You should have

• Substantial experience as a Principal Security Architect, Enterprise Security Architect or security design authority.
• Experience designing or assuring complex systems in large or regulated organisations.
• Strong knowledge of secure-by‑design principles, threat modelling and architecture assurance.
• Practical experience across cloud, hybrid infrastructure, identity, networks, applications and data security.
• The ability to distinguish genuine security requirements from unnecessary complexity.
• Excellent written English and the ability to explain technical risks to non‑technical decision‑makers.

We are particularly interested in applicants who hold

• UK Cyber Security Council professional registration at Principal or Chartered level in Secure System Architecture & Design.

We will also consider candidates who can demonstrate experience aligned with Chartered level and are willing to undergo formal professional assessment.

SABSA, TOGAF, CISSP, CCSP and cloud architecture certifications are useful, but do not replace the professional registration requirement.

You must be based in the UK, able to attend UK client sites when agreed, and able to contract through a limited company or another compliant arrangement.

Benefits

• Senior architecture and assurance assignments.
• Flexible associate working based on your availability.
• Direct access to Intelance leadership.
• Work alongside experienced enterprise architects, risk advisors and technical assessors.
• Clear scopes and independent advisory responsibilities.
• Potential inclusion in Intelance proposals and associate credentials, subject to agreement.

Please provide

• Your CV and Linked In profile.
• Your exact UK Cyber Security Council registration, specialism and registration number or public profile.
• If you are not registered, a short explanation of why your experience meets Chartered level.
• One example of a complex enterprise architecture you personally designed or assured.
• Your location, availability and expected day rate.
• Details of your architecture, cyber‑assurance and scheme‑related qualifications.
