The role will see you leading the delivery of drainage and flood risk projects from inception through to completion. You'll:
- Develop detailed hydraulic models
- Produce high-quality drainage strategies and Flood Risk Assessments
- Prepare technical drawings and reports
- Provide expert advice on surface water and wastewater management
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.
