These libraries underpin real-time and end-of-day risk workflows and ensure consistency between valuation, risk, and front-office systems. The role requires a technically skilled developer with a solid grasp of financial mathematics and derivatives pricing, capable of implementing and optimising complex models in a production setting. Key Responsibilities • Develop and maintain Python pricing and risk libraries covering vanilla and structured options across commodities and equities. • Implement and calibrate models such as Black–Scholes, Heston, SABR, and Monte Carlo-based approaches for structured instruments (APOs, CSOs, ULDs, P1X). • Design and maintain volatility surface calibration workflows, including interpolation, extrapolation, and smoothing. • Collaborate with quantitative researchers and data engineers to translate model specifications into robust, production-grade code. • Manage market data dependencies, proxy logic, and curve handling for valuation and risk analytics. • Enhance model performance, numerical stability, and diagnostic visibility. • Contribute to regression testing, benchmarking, and CI/CD workflows in Python and AWS environments. • Act as subject-matter expert for pricing models and valuation logic, supporting risk and trading teams globally. Skills and Experience • Expert-level Python developer with strong experience in numerical computing (NumPy, SciPy, Pandas). • Deep understanding of derivatives pricing theory, volatility modelling, and stochastic calculus. • Experience with calibration, curve bootstrapping, and risk measures (Greeks, sensitivities, VaR). • Background in pricing and risk models for commodities or equity derivatives. • Familiarity with cloud-based compute environments (AWS ECS, Lambda, S3) and DevOps tools (Git, Jenkins, Docker/Kubernetes). • Knowledge of C++ or C# for potential model integration advantageous. • Ability to interpret and implement quantitative research efficiently and transparently. Profile • 5–10 years of experience in quantitative development or model engineering within trading, banking, or commodities. • Advanced degree (Master’s or PhD) in Mathematics, Physics, Financial Engineering, or a related quantitative field. • Demonstrated delivery of robust pricing models and scalable production code. • Strong analytical skills and precision in solving complex numerical problems. • Excellent communicator, comfortable bridging quantitative, technical, and business perspectives. Why This Role Matters This position underpins the evolution of the firm’s global pricing and risk architecture. The Quant Developer ensures model integrity, accuracy, and scalability—contributing directly to trading performance and decision-making.
