Lead Data Security Engineer
We are seeking a Lead Data Security Engineer to design, implement, and continuously improve security controls that protect sensitive data across cloud, on-premises, and hybrid environments. You will provide technical leadership across data security initiatives, working closely with infrastructure, application, governance, risk, and compliance teams to embed secure-by-design principles throughout the organisation. The role will involve assessing data risks, defining security architectures, and translating regulatory and business requirements into practical, scalable solutions.
Key responsibilities include developing and maintaining data protection strategies covering encryption, tokenisation, masking, key management, data loss prevention, identity and access management, and secure data handling. You will lead security reviews for platforms, databases, APIs, analytics environments, and data pipelines; identify vulnerabilities and control gaps; and oversee remediation activities. You will also establish monitoring and detection capabilities, support incident response investigations, contribute to threat modelling, and help ensure that security controls are tested and evidenced effectively. As a technical lead, you will mentor engineers, influence architectural decisions, document standards, and communicate complex security topics clearly to both technical and non-technical stakeholders.
The successful candidate will bring substantial experience in data security engineering, cybersecurity architecture, or a related discipline, with a strong understanding of cloud security principles and modern data platforms. Practical knowledge of encryption technologies, secrets and key management, IAM, DLP, network security, vulnerability management, and security monitoring is essential. Experience with major cloud providers, infrastructure-as-code, CI/CD security, database technologies, and security automation would be highly valuable. You should be comfortable leading projects, balancing risk with delivery needs, and working within recognised security frameworks and privacy regulations. Relevant professional certifications or equivalent experience are desirable, alongside strong analytical, communication, and problem-solving skills.
