Quantitative Developer / Quant Platform Engineer

Commodities Trading
London, UK (hybrid/onsite)

Cititec are working with a commodities trading business that is rebuilding its quantitative technology capability. They are looking for an experienced Quant Developer to play a key role in designing, building, and enhancing the firm's pricing, risk, and quantitative infrastructure.

This position will sit within the technology function, working closely with quantitative researchers, traders, and technology teams to deliver robust, scalable platforms that underpin the firm's trading activities.

  • Designing and developing scalable pricing and risk platforms for commodity trading
  • Building production-grade quantitative libraries and analytics
  • Developing frameworks that support valuation, risk calculations, and market data processing
  • Working closely with trading, quantitative, and technology teams to understand business requirements and translate them into robust technical solutions
  • Improving existing quantitative infrastructure with a focus on reliability, performance, and maintainability
  • Supporting the evolution of the firm's overall quantitative technology architecture
  • Contributing to software engineering best practices, testing, and code quality across the platform

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.
