Water Quality and Coastal Modelling Consultant

Water Quality and Coastal Modelling Consultant

Understand Water. Model Change. Protect Our Environment.

Tetra Tech is seeking talented hydraulic modellers, engineers and environmental scientists to join our growing Water Quality and Coastal Modelling teams in Belfast. We work on a wide range of projects involving water quality assessment, hydrodynamic and coastal modelling, environmental impact assessment, marine consenting, offshore renewable energy, and coastal flood and erosion risk management.

This is an opportunity to contribute to technically challenging and environmentally important projects while developing your experience across water, coastal and marine environments. We have opportunities available at different levels, depending on your skills, knowledge and experience.

As a Water Quality and Coastal Modelling Consultant, you will support the delivery of numerical modelling, environmental assessment and water management projects. Your work may include coastal modelling of tides, waves, sediment transport and dispersion, as well as water quality assessments involving catchment delineation, rainfall and river-flow modelling, calibration and solution development.

You will collect, analyse and interpret hydrological, met‑ocean, spatial and environmental data, using the results to support technical reports, Environmental Statement chapters, marine consenting applications and client presentations. You will work closely with engineers, environmental scientists, planners, GIS specialists and project managers to deliver practical and evidence‑based solutions.

Depending on your experience, you may support defined technical tasks, lead specific work packages or take responsibility for elements of project delivery under the guidance of senior colleagues.

In the short term, you will contribute to high‑quality modelling, data analysis and technical reporting across live projects. As your experience develops, you will take greater ownership of technical tasks and work packages, contribute to client and stakeholder discussions, and support the delivery of environmental assessments and consenting applications.

Over time, you will have the opportunity to develop specialist expertise in water quality, hydraulic, hydrodynamic or coastal modelling and contribute to the growth of Tetra Tech’s water and environmental services across Ireland and the UK.

At Tetra Tech, we recruit using core capabilities—the essential skills, experience and behaviours required to perform the role effectively. There is no such thing as the perfect candidate, and we welcome applicants who meet most of the requirements and are keen to develop further.

You will have knowledge or experience in one or more relevant modelling areas, including water quality, hydraulic, hydrodynamic or coastal modelling. This may include catchment delineation, rainfall and flow boundary generation, river‑flow modelling, water quality calibration, tides, waves, sediment transport or dispersion.

You will be confident working with hydrological, met‑ocean, spatial and environmental data. You will be able to organise and quality‑check information, identify trends or anomalies, interpret modelling results and present your findings clearly in reports, figures, tables and presentations.

Strong attention to detail and the ability to explain technical information to both technical and non‑technical audiences are important for this role.
