Communications & Soft Skills
Ability to manage multiple tasks and projects while maintaining high-quality outputs. Excellent communication, organisation and problem-solving skills, with experience working effectively in multidisciplinary teams.

Leadership and Collaboration
Ability to build strong working relationships with clients and project partners, while supporting, guiding and developing junior and early-career engineers.
