• Support the development of our team through training, knowledge dissemination and mentoring.

• Degree qualification (or equivalent training and experience) in an appropriate environmental, physical science or engineering discipline.
• Significant experience in a comparable role (individual candidates need experience of some of the technical topic areas described above, not necessarily all).
• Good working knowledge of relevant regulations for nuclear site permitting and operations.
• Experience of bid leadership and proposal preparation.
• Ability to manage time and priorities while working on several varied projects.
• Excellent written and verbal communication skills, including tailoring outputs to the requirements of different stakeholders.
