How to Apply for Senior Aquatic Ecologist

at AECOM

🏢 About AECOM

AECOM is a global infrastructure consulting firm committed to delivering sustainable solutions that positively impact communities and the environment. Working here means joining a diverse team of experts who collaborate on high-profile projects, from habitat restoration to water resource management, with a strong emphasis on innovation and technical excellence.

About This Role

As a Senior Aquatic Ecologist, you will lead aquatic ecology inputs into Environmental Impact Assessments (EcIA) and multi-disciplinary projects across the UK. Your work will directly shape sustainable infrastructure by ensuring aquatic ecosystems are protected and enhanced, from survey design to mitigation strategies.

💡 A Day in the Life

A typical day might start with reviewing survey data from a recent river assessment, followed by a team meeting to plan upcoming fieldwork. You could then draft an EcIA chapter for a new infrastructure project, liaise with a client on mitigation options, and end the day reviewing a junior ecologist's report.
