How to Apply for Senior Flood Modeller

at AECOM

🏢 About AECOM

AECOM is a global infrastructure consulting firm committed to delivering sustainable legacies through innovative solutions. Working here means contributing to high-profile flood resilience projects that protect communities and the environment, with access to cutting-edge technology and a collaborative culture that values technical excellence and professional growth.

About This Role

As a Senior Flood Modeller at AECOM, you will lead the development and review of hydraulic models for flood alleviation schemes, flood risk assessments, and reservoir studies, using industry-standard software. Your work directly informs critical infrastructure decisions and helps shape resilient communities, while you also mentor junior staff and drive business development through tenders and client relationships.

💡 A Day in the Life

A typical day might involve reviewing model outputs from a TUFLOW simulation for a flood alleviation scheme, then leading a team meeting to discuss progress on a reservoir flood study. You could also mentor a junior modeller on hydrological analysis, followed by a client call to discuss tender requirements for a new framework contract.
