Lead Software Engineer / Developer

London / WFH

to £120k

Are you a skilled a backend-focused Python technologist with team leadership experience?

You could be progressing your career at a well-funded and profitable FinTech start-up.

About the Role

As a Lead Software Engineer, you'll head up a small, talented tech team to deliver new features and enhancements as well as some refactoring work, contributing to the core banking platform which integrates with major players such as HSBC. There's a relatively young codebase and lots of new projects to get stuck into.

You'll be collaboratively problem-solving in a hands-on role with approximately a 50/50 split between architecture/design and people management. You'll set the standards and mentor more junior developers, fostering a culture of continuous improvement and self-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.
