Job Description

The postholder will design and develop across the Claritas development stack, work closely with business teams to understand requirements, and help deliver secure, reliable and scalable solutions that support ongoing project delivery and operational efficiency. As part of a wider development team, the role also offers scope to contribute to broader development work and technology initiatives beyond Claritas.

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.
