Infrastructure Software Developer (Python) – Trading Firm – London – £140,000 + generous bonus

I'm working with a London-based trading firm that's investing heavily in how its infrastructure is built, and they're hiring a Python developer to write the software that runs it.

Established, technology-driven trading business
Small, collaborative engineering team
Real appetite to treat infrastructure as a software problem

This is a development role first and foremost. You'll sit within the infrastructure team, but your day-to-day will be designing, writing and maintaining the code and internal tools that replace manual work across the estate.

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.
