Senior Security Engineer, Operational Research and Development

Reference: ztx2fcpi3lqn3u23rf4q

We are seeking a Senior Security Engineer to lead operational research and development initiatives that strengthen the security, resilience and performance of complex technology environments. This role will combine hands-on engineering with structured investigation, enabling the organisation to assess emerging threats, validate defensive capabilities and develop practical solutions for evolving operational needs. You will work across security, infrastructure, software and operations teams to turn research findings into reliable, scalable improvements.

Responsibilities will include designing and conducting security research, technical experiments, proof-of-concept implementations and controlled assessments. You will investigate vulnerabilities, attack techniques, defensive technologies and operational risks; develop tools and prototypes; and evaluate their effectiveness through testing, monitoring and analysis. The role will also involve contributing to threat modelling, detection engineering, incident preparedness, security automation and the continuous improvement of technical standards. You will document results clearly, present recommendations to both technical and non-technical stakeholders, and help guide the transition of successful research into production-ready capabilities.

The successful candidate will have substantial experience in security engineering, research and development, or a closely related technical discipline. Strong knowledge of operating systems, networks, cloud technologies, secure software development and common attack and defence methodologies is expected. Experience with scripting or software development, security testing tools, automation platforms and laboratory or simulation environments would be highly beneficial. You should be comfortable working with incomplete information, questioning established approaches and communicating complex findings with clarity. A methodical approach to experimentation, strong analytical skills and a commitment to responsible security practices are essential. Relevant professional certifications or a degree in computer science, cybersecurity, engineering or a similar field are desirable, but demonstrable expertise and practical impact will be valued equally.
