Senior - Principal Backend Engineer | FinTech | London or Amsterdam
Join an early-stage Fintech building AI-powered infrastructure to simplify how businesses operate across borders.
International growth still comes with a lot of disconnected financial systems, manual processes and operational complexity. This team is bringing those pieces together into a platform that makes it easier for businesses to enter and operate in new markets.
The role
You’ll build core backend systems across payments, multi-currency ledgers, tax engines and workflow automation from scratch, taking ownership from early design decisions through to production.
Reasons to use Rodeo
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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The engineering team is small, so you’ll have significant influence over the architecture, work directly with the founders and help decide how the platform develops as the business grows.
Expect technically demanding work where correctness, reliability and scale matter, alongside the freedom to make decisions and see them through.
The team
You’ll join experienced engineers and operators who have helped build the likes of Revolut, Airwallex, Adyen & Yandex. They bring deep experience in payments and financial infrastructure, with strong funding behind them and plenty still to build.
