Shape projects from the earliest concept stages, embedding safety by design and an operations centred approach. Engage directly with a diverse range of clients, applying your design experience to help deliver tunnel systems projects for a growing client base including Local Authorities, National Highways, major airports and National Grid. Work closely with multidisciplinary teams to deliver high quality, client focused solutions that make a real difference - while benefitting from a supportive, collaborative culture that empowers you to grow, innovate and shape the future of key infrastructure. Play a key role in developing emerging talent, shaping a high performing technical team, and influencing WSP’s tunnel systems capability.
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.
