CBEC eco-engineering UK Ltd, part of the RSK Group, is seeking a Hydraulic Flood Modeller on a full-time permanent basis. This is a hybrid home, office-based role located in London, but working on sites throughout England and Wales. This is a newly created opportunity for a Hydraulic Flood Modeller to join our rapidly growing team.

CBEC eco-engineering is a leading UK environmental consultant specialising in the provision of eco-engineering solutions for the aquatic environment. The business offers innovative, ecologically sensitive, sustainable and process-based approaches using its expertise in geomorphology, river and wetland restoration, hydrology, hydraulic modelling and field services.

Key Responsibilities:

• Develop and refine hydraulic models, including setup, friction assignment (using site photographs and visits), and flood map preparation using GIS tools.
• Conduct quality assurance and control (QA/QC) of flood models, ensuring compliance with standards such as the EA Flood Model Assessment Tool.
• Engage confidently with the EA during model discussions and reviews, representing the team’s work with clarity.
• Collaborate with surveyors on-site to direct data collection essential for accurate modelling.
• Produce clear, well-written technical reports to communicate findings and recommendations.
• Work as an active member of the modelling team, contributing to project delivery and sharing insights.
• Support the Technical Director by providing updates on model setup and QA/QC, while confidently making sensible modelling assumptions.
• Assist with project tendering and costing, offering input based on your growing expertise.
• Participate in site visits across England and Wales and attend Southern team offices as needed.

Person Specification:

• demonstrable experience required in 1D-2D flood modelling (e.g., ideally Flood modeller/TUFLOW although other experience may be acceptable), with a solid foundation in hydraulic principles (there is flexibility for the experience we require, and mid and senior level candidates are of interest).
• Comfortable engaging with the EA and NRW in model reviews and discussions.
• Strong GIS skills for setting up hydraulic models and preparing flood maps.
• Practical experience assigning model frictions using site data and guiding surveyors to collect relevant information.
• Familiarity with flood model QA/QC processes (experience with tools like the EA Flood Model Assessment Tool is a plus).
• Enthusiasm for river restoration and nature based solutions alongside flood risk modelling.
• Good report-writing abilities to produce clear, professional documentation.
• A team-oriented mind-set, eager to collaborate and learn from others.
• Full UK driving licence with access to your own vehicle is preferred.
• An appreciation of 2D modelling benefits and a willingness to develop skills in tools like HEC-RAS and TUFLOW HPC. This role will specifically be involved with delivering TUFLOW HPC models, but we expect the candidate to learn ‘on the job’ for this type of modelling, working closely with our Technical Directors

Salary and Benefits

• Appointment will be dependent on experience and is offered at Senior Consultant lower (£30,750 - £41,000) or Senior Consultant Upper (£35, 875 -£51,250). The position may be considered at Principal Consultant (£41,000+) level for a candidate with an excellent fit to the company’s requirements and with requisite experience.
• A flexible benefits programme including the option to buy additional holidays, health cash plan and discounted gym membershi
