Principal Cyber Security Engineer
We are seeking a Principal Cyber Security Engineer to provide technical leadership across the design, implementation and continuous improvement of enterprise security capabilities. You will define security architecture and engineering standards, guide the adoption of secure-by-design principles, and advise technology and delivery teams on risk-based controls. The role will involve shaping security strategy, translating regulatory and business requirements into practical solutions, and acting as a senior technical authority for complex security decisions.
Key responsibilities will include leading the development of security patterns for cloud, on-premises and hybrid environments; assessing solutions, applications and infrastructure for vulnerabilities and design weaknesses; and overseeing the implementation of identity and access management, network security, endpoint protection, encryption, logging and monitoring controls. You will support threat modelling, security reviews, penetration testing and incident response, while helping to improve detection, resilience and recovery capabilities. You will also contribute to security governance, risk assessments, technical standards and remediation plans, working closely with engineering, architecture, operations, compliance and third-party teams.
The successful candidate will have substantial experience in cyber security engineering or architecture, with a strong understanding of modern infrastructure, cloud platforms, application security, networking and security operations. Relevant professional certifications or equivalent practical experience are desirable. You will be confident analysing complex technical risks, communicating clearly with both technical and non-technical stakeholders, and influencing outcomes without relying on direct authority. A track record of delivering security improvements in large or complex environments, alongside knowledge of recognised security frameworks and standards, is essential. The ability to mentor engineers, challenge existing approaches constructively and remain current with emerging threats and technologies will be central to success in this role.
