Associate Flood Modeller

Associate Flood Modeller
London (hybrid working available)

An established, global Engineering and Environmental Consultancy is looking to bring in an Associate-level Flood Modeller to strengthen their growing water and flood risk team in London. With a strong and varied pipeline across both public and private sector clients, this is a key role within a team delivering complex, high-impact flood risk and hydraulic modelling projects across the UK.

This position offers more than a typical modelling role. Sitting just below senior leadership, the successful individual will act as a key support to the team lead, taking on day-to-day responsibility for technical delivery, team coordination and project oversight. It's very much a step-up opportunity for someone ready to move beyond pure modelling into a broader leadership position, with a clear pathway into more senior responsibilities over time.

The role will see you providing technical leadership across a wide range of flood modelling projects, overseeing the development, execution and review of hydraulic and hydrological models to ensure outputs meet the highest quality standards and regulatory requirements. You'll be guiding projects from early concept through to submission, working closely with clients and ensuring alignment with Environment Agency standards and UK best practice.

Technically, you'll remain hands-on where needed, leading and reviewing complex models using software such as Flood Modeller, TUFLOW, ESTRY and InfoWorks ICM. You'll apply FEH methodologies, rainfall-runoff modelling and flood frequency analysis, while also interpreting outputs and translating them into clear, actionable insights for both technical and non-technical audiences.

A key part of the role will be quality assurance and governance. You'll be responsible for reviewing and signing off models, data inputs and reports, implementing robust QA/QC processes and ensuring consistency and auditability across all modelling work. This is a role for someone confident in their technical ability and comfortable taking ownership of final outputs.

Alongside technical delivery, there's a strong leadership element. You'll be mentoring and supporting junior and mid-level modellers, helping to develop capability within the team while also assisting with workload management and day-to-day team coordination. You'll play an important role in easing pressure on senior leadership, helping to keep projects moving and standards high.

There is also an opportunity to get involved in business development activities. Supporting bid preparation, contributing to proposals and helping to shape future workstreams will form part of the role, making it well-suited to someone looking to broaden their experience beyond delivery into the commercial side of Consultancy work.

This is a position where your impact will be visible. You'll help shape flood risk strategies that protect communities and infrastructure, while also playing a key role in strengthening the team's technical capability and supporting its continued growth.

They're looking for someone degree-qualified in a relevant discipline, with strong experience in flood modelling and a background in leading or checking technical delivery. Proven experience using industry-standard software and carrying out QA and sign-off of models is essential. A solid understanding of UK policy and regulatory requirements is expected, along with the ability to mentor others and manage multiple projects effectively. Chartered status (CIWEM or similar) would be advantageous but is not essential.

The role offers a flexible and supportive working environment, with hybrid working as standard and a good balance between office collaboration and home working. The London office is well connected, and there will be occasional travel for site visits and client meetings. Flexible working patterns are supported to help balance project demands with personal commitments.
