Quant Developer – Python
Location: London
Radley James is working with leading quantitative investment firms in London that are looking to hire experienced Python-focused Quant Developers to join their front-office technology and quantitative development teams.
These roles sit close to Portfolio Managers, traders, and quantitative researchers, building production systems and analytics that directly support investment and trading decisions.

This aligns with the attached role’s emphasis on Quant Developers working directly with researchers to build scalable software for research and trading across asset classes.
Key Responsibilities
- Design and develop high-quality Python applications and quantitative tools for front-office users.
- Work directly with PMs, traders, and quantitative researchers to translate requirements into production systems.
- Build and enhance analytics covering areas such as portfolio risk, exposures, pricing, PnL attribution, and trading performance.
- Develop scalable workflows and data pipelines for research, analytics, and trading.
- Work with large financial and market datasets across a range of asset classes.
- Investigate and resolve issues across data, positions, valuations, risk, and PnL.
- Take ownership of projects throughout the full engineering lifecycle.
- Improve the performance, reliability, and scalability of existing systems.
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.
