Principal Security Architecture Consultant

Reference: cqsr2co2xg4c81ec0qc8

We are seeking a Principal Security Architecture Consultant to provide strategic leadership and expert guidance across complex technology and information security initiatives. You will work with senior stakeholders, engineering teams, product owners and delivery partners to develop secure, resilient and scalable solutions aligned with business objectives, regulatory obligations and recognised industry standards. The role will involve translating business and technical requirements into practical security architectures, identifying risks and recommending proportionate controls across cloud, on-premises and hybrid environments.

Key responsibilities will include defining and maintaining security architecture principles, patterns, standards and reference designs; conducting architecture reviews and threat modelling; and providing assurance throughout the solution development lifecycle. You will assess proposed technologies, platforms and services, challenge design decisions where appropriate, and support the remediation of security risks. You will also contribute to security strategy, roadmaps, policies and governance forums, while helping to strengthen secure-by-design practices across programmes and operational teams. The position requires the ability to communicate complex security matters clearly to both technical and non-technical audiences and to influence decisions at senior levels.

The successful candidate will have substantial experience in security architecture, consulting or a closely related discipline, with a strong understanding of enterprise security principles, identity and access management, network security, application security, data protection, cryptography and cloud security. Experience with architecture frameworks, risk management methodologies, threat modelling techniques and relevant standards such as ISO 27001, NIST or CIS is highly desirable. Professional security or architecture certifications would be advantageous. You should be analytical, pragmatic and commercially aware, with excellent stakeholder management, communication and influencing skills. A proven ability to lead complex work, manage competing priorities and deliver clear, actionable recommendations in fast-changing environments is essential.
