  • 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
