About the Role
We are seeking a Distinguished Quantitative Engineer for a high-impact, senior individual-contributor contract role based in London. This is a position for a seasoned professional with 15+ years of demonstrable experience independently designing, implementing, and delivering production-grade pricing and risk models for complex exotic derivatives across Equity, Rates, FX, and Commodities. We require deep, hands-on ownership. You will be responsible for everything from mathematical formulation and numerical implementation to performance optimisation and direct contribution to live analytics and trading systems.
What You Will Do
- End-to-End Model Ownership: Independently design, implement, and validate pricing and risk models for complex and exotic OTC derivatives (from math formulation to production rollout).
- Core Library Evolution: Build and evolve core analytics libraries used for valuation, sensitivities, scenarios, and XVA.
- Advanced Numerical Implementation: Implement advanced numerical techniques including Monte Carlo methods (with variance reduction), Tree/lattice methods, PDE approaches, and curve construction (bootstrapping/interpolation).
- High-Performance Engineering: Deliver low-latency, high-performance implementations optimised for large books and intraday risk.
- Codebase Evolution: Review, debug, and optimise existing quantitative codebases for correctness, stability, and scalability, setting the technical standards for implementation rigor.
Required Experience & Technical Skills
- 15+ Years of Hands-On Experience: A proven track record as a quantitative developer/engineer (bridging pure modeling and pure software engineering).
- Production Delivery: Proven experience personally authoring and deploying production pricing libraries, risk engines, exotic payoff models, or calibration frameworks.
- Cross-Asset Exotic Domain Expertise: Deep understanding of exotic derivatives across Equity, Rates, FX, and/or Commodities, including front-to-back derivative lifecycles.
- Technical Stack: Strong production experience in Java is essential alongside C++ and/or Python writing numerically intensive code (not just scripting).
- Numerical Computing: Solid understanding of algorithm design, performance optimisation, memory management, and distributed systems.
- Domain Depth: Practical experience with cashflows, resets, curve frameworks (OIS, multi-curve), sensitivities, scenario risk, and regulatory measures.
What This Role Is NOT
- Not a people-management or team-lead position.
- Not a pure research or academic quant role.
- Not an architecture-only or "ivory-tower" position.
- Not suitable for candidates without direct, hands-on production code ownership.
Education
Advanced degree (Master's or PhD preferred) in Mathematics, Physics, Engineering, Computer Science, or equivalent senior-level commercial experience.
To Apply
If you are a highly autonomous, accountable expert who can deliver tangible outcomes quickly in a complex environment, we want to hear from you. Please submit your CV highlighting the quantitative components and libraries you have personally authored and moved into production.
