• Deliver: Lead and input into tenders ranging from innovative one‑off projects to multimillion‑pound framework contracts. Produce and review high‑quality technical reports documenting model build and uncertainties in the model build process. Conceptualise and scope modelling and hydrological approaches, with consideration of the risks and opportunities in each.
• Collaborate: Work closely with our clients and teams of engineers and technical specialists to help our clients deliver a wide range of fluvial, coastal, surface water or drainage flood risk management projects.
• Lead: Mentor staff within the team to support their professional development and build relationships with clients and across other technical disciplines.
• Quality: Keep up‑to‑date with developments in legislation and guidelines that may affect our services. Use AECOM’s project management systems to deliver high‑quality outputs to our clients in line with the agreed programme and budget.
