• Take ownership of the civil scope within multidisciplinary delivery, promoting best practice and innovation while driving clear decisions on operability, maintainability, access, and whole-life performance. 
• Lead the development of surface water drainage strategies and the delivery of outline and detailed surface water drainage design (including hydraulic modelling), promoting the use of sustainable drainage systems (SuDS) and nature-based-solutions for a range of clients in the regulated and non-regulated water sector.
• Lead and support on the civil aspects of appraisal, feasibility, optioneering, design and delivery of flood and erosion risk management projects.
• Work on flood risk assessments advising clients on the most appropriate solutions to mitigate flood risk through design in line with policy and regulation.
• Support the development of the team’s expertise in river engineering and river restoration.

• Act as a senior client-facing technical lead, running workshops and design reviews, advising clients, and building long-term relationships with clients both in the regulated and non-regulated water sectors.
• Provide design assurance and technical support during delivery phases, including reviewing contractor submissions, answering design queries, and supporting handover/commissioning activities when required.

Business Growth & Team Development

• Grow the civil capability through business development and work winning: identify opportunities, shape scopes, contribute to bids, and build a healthy forward pipeline.
• Help translate the UK water growth strategy into practical actions: target sectors, priority accounts, capability gaps, and delivery plans.
• Help in building the civil arm of the UK water consultancy team through recruitment, mentoring and skills development, including pathways, coaching and technical governance.

• Demonstrable experience in Microdrainage / Infodrainage and drainage related hydrology.
• A strong interest for nature-based-solutions and the desire to champion a more strategic and sustainable approach to water management would be highly beneficial.
