About the Organisation
Our client is a specialist UK consultancy operating at the intersection of hydrology, environmental science, and software development. Established in the early 2000s, the business is nationally recognised for developing industry-standard hydrological and flood estimation tools used widely by regulators, consultants, and practitioners across the UK.
The company combines scientific research with commercial software development to deliver cost-effective, sustainable solutions for water resources, flooding, and climate change. As an employee-owned organisation, it offers a supportive, dynamic working environment with a strong focus on professional development, collaboration, and shared success.

The Role

The successful candidate will join the organisation's software development and science team, playing a key role in the development and ongoing management of national hydrological modelling tools and methods.
You will work on software that underpins UK national design standards, addressing real-world challenges including river seasonality, flood mitigation, and climate resilience. The initial focus of the role will be on a national water resources modelling platform, with opportunities to contribute across a broader flood modelling software suite.
A key element of the role will involve applying machine learning techniques alongside established hydrological models to enhance performance, insight, and innovation.

Key Responsibilities

Develop and manage hydrological methods within a national water resource modelling platform.
Contribute to the development and enhancement of UK flood estimation and modelling tools.
Identify and implement machine learning approaches to support and extend existing hydrological models.
Translate scientific research into robust, user-focused commercial software solutions.
Support software testing, validation, and user interface development.
Engage with regulators and end users to ensure compliance, credibility, and usability of tools.

Ability to work with complex spatial and temporal datasets (e.g. NetCDF, ASCII formats).
Strong written and verbal communication skills, with the ability to engage both technical and non-technical audiences.
Demonstrable experience in hydrology or water-related environmental science.
