Senior Technical Security Consultant - H&PS
We are seeking a Senior Technical Security Consultant to provide expert advice and practical guidance across complex technology and security programmes within highly regulated and business-critical environments. The role will involve working with clients and internal delivery teams to understand security needs, assess risks, and develop proportionate solutions that support operational, regulatory, and strategic objectives. You will contribute throughout the project lifecycle, from early discovery and requirements definition through to design, implementation, assurance, and transition into service.
Key responsibilities will include conducting security assessments, threat modelling, risk analysis, and technical reviews; developing secure architectures, controls, standards, and implementation plans; and advising on cloud, infrastructure, applications, networks, identity, data protection, and emerging technologies. You will produce high-quality security documentation, including architecture decisions, risk registers, control assessments, security cases, and remediation plans. The role will also require close collaboration with architects, engineers, programme managers, suppliers, and senior stakeholders, translating complex technical matters into clear, actionable recommendations. You may also support incident readiness, compliance activities, technical assurance, and the development of security patterns and best practice.
Applicants should have substantial experience in technical security consulting, security architecture, or a closely related discipline, with a strong understanding of recognised security frameworks, risk management methodologies, and secure design principles. Relevant professional certifications such as CISSP, CISM, SABSA, or equivalent experience are desirable. You should be confident operating across multiple projects, prioritising competing demands, and influencing decisions without relying on direct authority. Strong analytical, communication, report-writing, and stakeholder management skills are essential, together with the ability to challenge constructively and provide pragmatic advice. Experience of working in regulated, public-facing, or highly complex environments would be advantageous.
