London | Hybrid | Fintech

The Role

A fast-growing fintech is building a new in-house engineering team and is looking for a Senior Back-End Developer to become a key technical hire.

You’ll take ownership of a modern platform built with C#/.NET microservices, PostgreSQL, Redis, and Google Cloud, helping shape architecture, engineering standards, and future development.

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.
