EVERYTHING YOU NEED TO KNOW
We’re looking for a Senior Modeller to join our Risk Validation team, with responsibility for confirming model fitness for use to meet Severn Trent Water design standards and project specific requirements.
In this role, you’ll be evaluating the wastewater network performance to identify new/validate existing risks and needs. Developing notional solutions for projects that will be passed over to the capital delivery teams for further feasibility and design, you’ll be delivering improvements to Severn Trent Water’s wastewater network in line with the company’s business plan. Some of the typical risks that will require validation will include sewer flooding, growth, water framework directive / CSO performance and sewage pumping station performance.
You’ll also lead project specific hydraulic modelling requirements, including model audits/fitness for use assessments, model build and verification, and risk validation of catchment drivers.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
