Principal Engineer - Human-Centric Technologies (Defence & Security)

This position involves designing and building intelligent systems that perceive, reason about, and adapt to human behavior in real time using multi-modal sensing. The role requires conducting human subject studies, evaluating empirical data, and synthesizing scientific insights to guide technology development. You will also perform deep literature reviews in experimental psychology, cognitive science, and human factors to translate complex concepts into engineering requirements. As a senior technical voice, you will act as the technical lead on complex projects, owning the solution and its value to the client. Additionally, you will develop proposals and costed work programmes to win new business and set the technical direction for the department. The job demands security clearance due to the nature of the defence and security work, though you will not work exclusively in that sector. A genuine interest in this field is essential for the role. The working arrangement is hybrid, with a flexible approach, although some projects may require full-time office attendance. The advert does not specify particular software tools, formal qualifications, or language requirements beyond the implied need for clear communication in a professional setting. This role suits a senior engineer with a strong background in human-centric technologies who is comfortable with both hands-on research and client-facing activities.
