How to Apply for Senior Water Scientist and Hydrologist

at AECOM

🏢 About AECOM

AECOM is a global leader in infrastructure and environmental solutions, known for delivering innovative projects that build sustainable legacies. Working here offers the chance to collaborate with multidisciplinary experts on high-impact water science initiatives across the UK, with a strong emphasis on technical excellence and client-driven outcomes.

About This Role

This role involves leading water science services from bid preparation to project delivery, including complex fieldwork, hydrological modeling, and multidisciplinary team coordination. As a Senior Water Scientist and Hydrologist, you'll directly contribute to solving critical water resource challenges while driving commercial success through high-quality bids and client relationships.

💡 A Day in the Life

A typical day might involve reviewing bid documents in the morning, then leading a team meeting to coordinate fieldwork logistics for a river restoration project. After lunch, you could analyze hydrological data using MIKE SHE, followed by a client call to discuss project milestones. The day often ends with updating project budgets and planning next week's monitoring campaign.
