Experience delivering work across multiple project stages, from early studies and concept design through construction and commissioning.

Proven ability to lead technical teams, manage interfaces and coordinate multidisciplinary design delivery.

Strong understanding of design risk, technical assurance, quality management and the responsibilities of a senior design leader.

Confident client-facing skills and the ability to explain complex technical matters clearly to different audiences.
