Security Architecture Lead
We are seeking an experienced Security Architecture Lead to define and advance the security architecture strategy across a complex technology environment. This is a senior role for a pragmatic security professional who can translate business objectives and emerging threats into effective, scalable and proportionate security solutions.
You will lead the development and maintenance of security architecture principles, standards, patterns and roadmaps. Working closely with technology, engineering, risk, compliance and business stakeholders, you will ensure that security is embedded throughout the design, delivery and operation of services. You will provide authoritative guidance on cloud, infrastructure, applications, data, identity and emerging technologies, while supporting informed decisions around risk and investment.
Key responsibilities will include reviewing solution designs, identifying security risks and control gaps, and defining appropriate mitigations. You will establish and promote secure-by-design practices, contribute to architecture governance, and oversee exceptions where requirements cannot be met. The role will also involve assessing new technologies and suppliers, supporting threat modelling, contributing to incident learning, and ensuring architecture remains aligned with relevant legislation, regulatory expectations and recognised industry standards.
You will bring substantial experience in security architecture, cyber security engineering or a closely related discipline, gained in a complex or regulated environment. A strong understanding of cloud security, network architecture, application security, identity and access management, data protection and security operations is essential. Experience with architecture frameworks, threat modelling techniques and risk management approaches will be highly valued, as will relevant professional certifications.
We are looking for someone who can communicate complex technical matters clearly to both technical and non-technical audiences. You should be confident influencing senior stakeholders, challenging constructively and building strong relationships across multidisciplinary teams. A structured, analytical and collaborative approach is essential, alongside the ability to balance security requirements with usability, delivery priorities and commercial considerations.
This role offers the opportunity to shape security strategy, strengthen organisational resilience and make a visible contribution to the safe delivery of technology and services.
