You’ll combine technical depth with sound judgement, commercial awareness and confident communication, enabling you to build credibility with senior customers and provide clear, evidence-based technical advice even where information is incomplete or uncertain. You’ll also be passionate about developing others and strengthening technical capability through mentoring, improved methods and professional communities. A relevant engineering, scientific or technical qualification, or equivalent professional experience, is expected, with Chartered Engineer status or an appropriate route towards Chartership preferred.
