- Collaborating with multidisciplinary teams, including civil, process, electrical, and environmental engineers, to develop integrated solutions that improve water quality, protect the environment, and meet client objectives.
- Assisting with site visits, inspections, and surveys, gathering information and supporting the assessment of existing assets to inform upgrades, refurbishment projects, and future investment strategies.
- Engaging with equipment suppliers, contractors, and clients, helping to review technical submissions, resolve engineering challenges, and ensure projects are delivered to required standards of quality, safety, cost, and programme.
- Contributing to sustainability and innovation initiatives, supporting projects that improve energy efficiency, reduce carbon emissions, enhance asset performance, and strengthen the long-term resilience of public water and wastewater services.
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.
