Are you a recent graduate looking to launch a career in flood risk and drainage consultancy, or already working at assistant level and ready for your next step? Are you looking for a flexible, remote-based role where you can develop real technical skills on live projects from day one? Are you seeking hands-on mentoring, structured CPD, and a clear route to becoming a chartered professional?

If you answered yes to any of the above…then this could be your opportunity to be part of an experienced, dynamic and fast-paced team within a successful, multi-disciplinary consultancy.

You'll be supported by experienced engineers as you learn to prepare FRAs, design drainage strategies, and engage with planning authorities, LLFAs, and water companies. If you already have consultancy experience, you'll take on your own projects sooner and your salary will reflect that.
