We are working with a fast-growing environmental consultancy that is seeking a Senior Environmental Data Scientist / Hydrologist to join its team in the Wallingford area. This position is ideal for someone who thrives in a collaborative scientific environment and wants to deepen their expertise in hydrological modelling, data analysis and environmental software development.


Role Overview


The successful candidate will join a multidisciplinary science and software team responsible for designing, improving and maintaining national hydrological modelling systems. These tools support key decisions relating to river behaviour, flood mitigation and long-term water management.


A major focus of the role will be on enhancing a widely used water-resource modelling platform, along with contributing to updates of national flood-estimation tools. The position also involves exploring ways machine learning can be integrated into existing hydrological methods to improve accuracy and expand capability.


Key Responsibilities


• Develop and refine hydrological modelling methods for a national water-resources platform
• Contribute to the enhancement of leading flood-estimation tools used across the UK
• Research and apply machine learning techniques to hydrological datasets
• Incorporate scientific findings into commercial software, including interface testing and usability improvements
• Work closely with regulators, end users and technical specialists to ensure tools remain accurate, compliant and user-friendly
• Support ongoing scientific research and translate outcomes into practical solutions


Skills & Experience Required:


• A good degree (2:1 or above) in a numerate or environmental discipline such as hydrology, earth sciences or civil engineering; postgraduate study is welcome but not essential
• Strong programming capability in Python and/or R
• Experience designing or applying machine learning models to environmental or geospatial data
• Ability to process and analyse complex datasets such as spatial or time-series formats (e.g. NetCDF, ASCII)
• Strong communication skills, able to explain technical concepts to both specialists and non-specialists
• Demonstrated knowledge or experience in hydrology, water-environment work or related environmental science


What the First Year Looks Like:


During the first 12 months, the new team member will:
• Build familiarity with the organisation’s hydrological modelling tools and software suite
• Develop Python modules and apply ML approaches to real hydrological challenges
• Gain an understanding of the UK’s regulatory framework for water and flood-risk activities
• Collaborate with partner research institutions and engage with national regulators
• Produce high-quality technical reports and documentation
• Begin progressing toward professional chartership (e.g., CIWEM or equivalent)


As experience grows, they will have opportunities to:
• Contribute to long-term scientific and commercial development strategies
• Identify innovative opportunities for new products, capabilities or modelling approaches
• Lead elements of research and development projects
• Support the preparation of client proposals


Benefits & Culture:
• Employee-ownership structure with tax-free profit-share bonuses
• Additional performance-related bonus opportunities
• Clear pay bands and transparent promotion pathways
• Share-option opportunities for senior grades (subject to tenure)
