As a Quantitative Developer you will work at the boundary between quantitative research and production engineering, building the systems and datasets our researchers and traders depend on. You will partner directly with quants across the firm, and own the infrastructure that turns research ideas into results that can be trusted and repeated.

• Partner with quantitative researchers and traders to understand their research questions, and design the data, tooling and compute to answer them

• Build, operate and optimise the pipelines and execution frameworks behind our research and backtesting

• Take research prototypes into production, with the reliability, reproducibility and observability that production requires

• Own foundational shared datasets used across multiple desks, including their quality and timeliness

• Profile and optimise performance-critical numerical code, balancing runtime against compute and storage cost

• Migrate existing research pipelines onto modern data platforms, and improve the process for the migrations that follow

• Build evaluation tooling that lets researchers judge model performance

• Collaborate across the wider data and technology organisation to improve the platform every desk builds on
