- Collaborate with experts across the UK and globally as part of WSP’s international Practice Area Network in flood and weather forecasting.

Your work will be varied and challenging and is likely to include:
- Delivering and leading flood forecast modelling and hydrology studies using tools such as Flood Modeller, PDM and hydrodynamic routing.
- Preparing and reviewing model boundaries, undertaking rating reviews and completing performance testing.
- Carrying out quality assurance and independent technical reviews of forecast products.
- Producing clear, high quality client and public facing deliverables and contributing to the visualisation of complex data.
- Supporting the development of WSP’s flood forecasting service offering.
- Mentoring less experienced modellers.
- Supporting or leading bid proposals and helping develop innovative solutions for clients.
- Managing project delivery including commercial, financial and stakeholder aspects.
- Collaborating with UK and international WSP teams.
- Promoting a safety first approach in line with WSP policies and procedures.

Your Team
Our national fluvial and pluvial modelling team delivers flood modelling (real time and non-real time) to support a broad portfolio of work including flood warning improvements, FCERM studies and strategic infrastructure projects across energy, transport, government and water sectors.

As an experienced flood forecast modeller, you will be part of the growing UK based real time modelling capacity, supporting junior colleagues and contributing to WSP’s international Practice Area Network focused on flood and weather forecasting.

We offer a dynamic but supportive environment for a motivated and talented individual to fulfil their potential. We recognise that our people are central to our success as a business.
