How to Apply for Principal Water Quality Modeller

at AECOM

🏢 About AECOM

AECOM is a global infrastructure consulting firm that stands out for its commitment to 'building sustainable legacies' through innovative environmental solutions. Working here means contributing to high-profile UK and international projects that address critical water quality challenges while collaborating with multidisciplinary teams of hydrologists and engineers.

About This Role

As a Principal Water Quality Modeller at AECOM, you'll lead technical water quality assessments for rivers, lakes, and coastal waterbodies, using specialized tools like MIKE+ and InfoWorks ICM. This role is impactful because you'll develop innovative modelling solutions that directly inform environmental impact assessments and help clients meet regulatory requirements while mentoring junior staff and contributing to business development.

💡 A Day in the Life

A typical day might involve leading a virtual team meeting to coordinate a river water quality assessment, building or checking models in MIKE+ for an environmental impact study, reviewing technical reports from junior staff, and participating in client calls to discuss modelling approaches. You'll balance hands-on modelling work with strategic contributions to bids and mentoring activities.
