As Chief Safety & Risk Consultant - Human Factors within Assystem’s Safety & Risk business, you will lead the strategic development and growth of our Human Factors capability across nuclear, defence and critical infrastructure programmes. This is a senior leadership role where you will shape direction, define service offerings and ensure our capability aligns with evolving client needs and market demand.

Alongside this, you will provide technical oversight on projects, ensuring that Human Factors is effectively integrated into engineering, safety and operational decision-making.

A key part of the role will be building and developing capability—leading technical teams, mentoring individuals and driving continuous improvement in methods, tools and ways of working.

You will bring deep expertise in Human Factors, with experience applying the discipline within nuclear, defence or other high-hazard environments. A strong track record in technical leadership, capability development or strategic roles is essential, along with the ability to translate client needs into practical, value-driven solutions.

You will be comfortable operating at senior level, engaging with clients, influencing stakeholders and managing competing priorities.

A relevant degree in Human Factors, ergonomics, psychology or a related discipline is required. Professional recognition (e.g. CIEHF membership) is desirable.
