Job Description

Are you into flood risk management and looking for your next exciting opportunity? We are seeking senior InfoWorks ICM flood modellers to join our thriving business and work on projects across the UK. If this describes you, we want to hear from you and discuss how we can help develop your career!

We have UK-wide vacancies for enthusiastic and ambitious individuals to lead and undertake projects in our world-class flood risk management team. We seek technical experts with a developing technical profile in flood risk management, capable of leading hydraulic and hydrological modelling projects, including 1D and 2D models for rivers, surface water, and coastal waters, with a focus on InfoWorks ICM software.

As a major engineering, environmental, and design consultancy, AtkinsRéalis offers opportunities for talented consultants to work on diverse projects at various scales. Our ongoing projects include flood risk management frameworks for the Environment Agency and local authorities in England, Scotland, Wales, and Northern Ireland, as well as major projects like Sizewell C and Lower Thames Crossing. We also work in natural flood management, flood forecasting, flood alleviation, and water resource and quality issues for water companies. Internationally, we are engaged in projects in the Red Sea economic zone, Al Bada developments in the Middle East, and EIA work in North America. All projects are managed with our colleagues in India, working as part of an international team.

Check out some of our recent, exciting projects.

Requirements:

You should have experience in delivering flood risk projects with a focus on integrated catchment modelling using ICM software, with the confidence to lead technical work and mentor junior team members. You should be able to build strong client relationships with collaborative skills to ensure effective working relationships.

Essential for this role:

Advantages for this role:

• Experience with other software like Flood Modeller, TUFLOW/ESTRY, or HEC-RAS.
• Knowledge of FEH hydrological assessment and UK hydrology is desirable.

Responsibilities:

• Lead detailed technical work involving ICM hydraulic modelling, data analysis, GIS, and reporting, with quality assurance responsibilities.
• Manage, supervise, and mentor junior staff.
• Support project managers and directors by following procedures, including financial and change control.
• Work effectively within a team and with other professionals to provide integrated services.
• Contribute to business development, tendering, and stakeholder engagement.

The Individual:

• Motivated, proactive, and committed to technical excellence.
• Excellent collaborative and interpersonal skills, with effective communication.
• Flexible and open to new challenges.
• Organized, able to manage multiple projects, and delegate effectively.
• Detail-oriented with high standards of work.

Competitive salary, 25 days leave plus bank holidays, with options to buy or sell leave. Benefits are aligned with experience and qualifications.
