Quantitative Analyst — Front Office Analytics
About Calypso (a Nasdaq product)
Nasdaq Calypso delivers mission-critical risk, regulatory, and trading technology to the world's largest financial institutions. The platform powers trading and trade processing across every major asset class — FX, rates, equities, credit, commodities, and digital assets — serving hundreds of banks, broker-dealers, asset managers, and central counterparties globally.
Our Quantitative Analytics team sits within a global organization of 10,000+ colleagues with offices across North America, EMEA, and APAC. We combine the engineering depth of a leading fintech with the scale, stability, and client reach of a publicly listed market infrastructure leader.
This role is based in Mumbai and operates on a hybrid working model (typically 3 days in office, 2 days remote).
Role Overview
We are hiring a Quantitative Analyst to join our Front Office Analytics team. You will design, implement, and productionize pricing and risk models used directly by our clients' trading desks.
This is a hands-on quant role: you will own models end-to-end, from mathematical derivation through C++/Python implementation, performance optimization, testing, documentation, and client support. Our library covers all major asset classes, so you'll have exposure well beyond any single desk.

What You'll Do

• Develop and maintain pricing, risk, and XVA models across rates, FX, credit, equity, and/or commodities

• Translate mathematical specifications into high-performance, well-tested production code

• Work directly with clients' quants and traders to calibrate, validate, and extend models to new products and markets

• Partner with Engineering on performance (vectorization, GPU/parallel compute, AAD/adjoint sensitivities)

• Give to our AI/ML initiatives for model acceleration, calibration, and anomaly detection

• Write clear technical documentation and defend methodology in model validation reviews

Skills & Requirements

Required

• 5+ years as a quantitative analyst in derivatives analytics (any asset class considered)

• Strong development skills in C++ (modern C++17/20) and/or Python; comfort with Git, CI/CD, and code review culture

• PhD (or equivalent research experience) in Mathematics, Physics, Engineering, Computational Finance, or a related quantitative field

• Solid grounding in stochastic calculus, numerical methods (Monte Carlo, PDE, finite difference), and derivative pricing theory

• Passion for writing industrial-strength, reusable analytics code

Nice to have

• Experience with AAD / algorithmic differentiation libraries

• Exposure to XVA, SIMM, FRTB, or IM/VM calculation engines

• ML/AI applied to pricing, calibration, or risk (PyTorch, JAX, scikit-learn)

• Cloud-native development (AWS / Azure / GCP), containers, Kubernetes

• Experience contributing to a vendor or sell-side production analytics library

What We Offer
• Competitive base salary and discretionary performance-based bonus
• Nasdaq equity (RSUs) and employee stock purchase plan
• Comprehensive health, retirement, and wellbeing benefits
• Hybrid working, generous leave, and paid learning & conference budget
• A global team of quants, engineers, and researchers working on problems that directly move markets
