Tetra Tech 2027 Graduate Scheme: Your launchpad to a consultancy career
Join Tetra Tech’s two-year Graduate Scheme and begin your career with hands-on experience, expert mentorship and a tailored development plan. You’ll work on a variety of real-world projects, develop technical and professional skills, and be encouraged to share your ideas and shape your future.
We are seeking talented graduates to join our growing Water Quality and Coastal Modelling teams in Belfast. You’ll contribute to technically challenging and environmentally important projects involving water quality assessment, hydrodynamic and coastal modelling, environmental impact assessment, marine consenting, offshore renewable energy, and coastal flood and erosion risk management.
Purpose & scope of the role
As a Graduate Water Quality and Coastal Modelling Consultant, you’ll work alongside experienced engineers, modellers and environmental scientists to support the delivery of water, coastal and marine projects.
You’ll gain exposure to a diverse range of technical activities, which 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.
Working with hydrological, met-ocean, spatial and environmental data, you’ll learn how to analyse and interpret information to support technical reports, Environmental Statement chapters, marine consenting applications and client presentations. You’ll work closely with engineers, environmental scientists, planners, GIS specialists and project managers to help deliver practical, evidence-based solutions.
From the outset, you’ll be supported by experienced industry specialists and given opportunities to develop your technical knowledge across water, coastal and marine environments. This is an excellent opportunity to build your career within a leading consultancy while contributing to projects that support sustainable development and protect our natural environment.
Your impact in this position
As a Graduate Water Quality and Coastal Modelling Consultant, you’ll support the delivery of modelling, data analysis and environmental assessment projects across Ireland and the UK.
In the short term, you’ll contribute to defined technical tasks, including organising and quality-checking data, supporting modelling activities, preparing figures and tables, and contributing to technical reports. You’ll also have opportunities to attend client meetings, participate in site visits and gain an understanding of the wider project delivery process.
As your experience develops, you’ll take greater ownership of technical tasks and contribute to defined work packages under the guidance of senior colleagues. You’ll gain valuable experience supporting environmental assessments, marine consenting applications and projects relating to water quality, offshore energy, marine development, coastal flooding and erosion risk management.
With the support of senior colleagues, structured mentoring and a comprehensive graduate development programme, you’ll build the technical knowledge, practical experience and professional confidence needed to progress your career. You’ll also have the opportunity to develop specialist expertise in water quality, hydraulic, hydrodynamic or coastal modelling.
