• Support flow survey scoping, survey verification and the development of catchment‑scale strategic solutions.
• Prepare model outputs, calculations, maps, option appraisal material and technical reports for review and issue.
• Coordinate technical tasks with Manila team members and wider AECOM project teams.

Technical Quality and Leadership

• Identify data gaps, model confidence issues, assumptions and risks, and propose practical actions to resolve them.
• Mentor junior modellers and support their technical development through task guidance and review feedback.
• Support technical innovation, workflow improvement and appropriate application of modelling tools and data management methods.
• Build positive working relationships with project managers, technical leads, client‑facing teams and colleagues across offices.

Qualifications

• Bachelor's degree in Civil Engineering, Environmental Engineering, Environmental Science, GIS, Geography, Water Resources or a related discipline.
• Professional membership or progress towards a recognised engineering, water or environmental professional qualification would be beneficial.

Essential Experience

• Proven experience in hydraulic modelling, water consultancy, wastewater, drainage, flood risk, GIS or data analysis.
• Good knowledge of hydraulic modelling or asset management software, preferably InfoWorks ICM and / or InfoAsset.
• Experience using GIS tools such as ArcGIS, QGIS or MapInfo to support modelling and spatial analysis.
• Ability to check models, calculations and technical deliverables with a strong focus on quality and traceability.
• Ability to prepare clear technical documentation and communicate modelling findings in English.
• Ability to work independently on defined technical tasks while escalating risks and assumptions appropriately.

Desirable Experience

• Experience supporting UK, Ireland, Australia, New Zealand or other international water infrastructure projects.
• Experience with 1D / 2D modelling, floodplain mapping, river modelling, pluvial modelling or integrated catchment modelling.
• Experience with HEC‑RAS, TUFLOW, Flood Modeller Pro, MicroDrainage, HY‑8, XP‑RAFTS or similar tools.
