Supporting hydraulic modelling tasks such as network model builds, upgrades, calibration, operational response assessments and mains flushing programme development. Contributing to asset risk prioritisation modelling and helping collate inputs for analysis. Supporting water quality modelling activities, option assessments, and the development of technical solutions. Helping undertake growth studies and network capacity checks. Working with senior team members to ensure projects meet client expectations for quality, time and budget. Taking responsibility for your own continuing professional development, supported by your People Manager and senior colleagues, and assisting with basic tasks or knowledge sharing for junior team members where appropriate. Operating in accordance with corporate health, safety, environmental and quality standards, as well as associated client requirements. Helping maintain project‑related health and safety strategies, including preparation of risk assessments. Supporting general project delivery activities such as data analysis, report preparation, and document control. Successful candidates will become part of a respected and ambitious team, with excellent opportunities for technical and professional growth.
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.
