Job Description

CW Talent Solutions is partnering with a world-renowned, multi-strategy investment firm to appoint a Quantitative Developer for its premier London Fixed Income desk. This is a front-office aligned role where software engineering meets high-finance research. You will not be building in isolation; instead, you will be embedded with Portfolio Managers and Researchers to architect the systems that drive some of the firm’s most successful systematic and discretionary strategies.

In this role, you are the bridge between raw data and executable alpha. You will be responsible for the “productionization” of complex mathematical models, turning innovative research into resilient, high-performance trading tools. Whether it’s optimizing a credit pricing engine or refining a global macro data pipeline, your work will directly underpin the firm’s daily P&L.

Key Responsibilities

Infrastructure Evolution: Architect and maintain the core research and trading platforms specifically tailored for fixed income products (rates, credit, and derivatives).
Tool Development: Design and deploy production-grade pricing engines, risk monitoring tools, and real-time analytics dashboards.
Data Engineering: Build and manage high-scale data pipelines capable of handling massive historical and real-time market datasets.
Collaborative Research: Work side-by-side with Quants to translate mathematical signals into scalable code, ensuring model integrity and performance.
System Optimization: Continuously improve the latency, scalability, and reliability of the firm’s systematic investment frameworks.

Requirements

Experience: Minimum of 2+ years as a Quant Developer or Software Engineer within a trading, research, or high-performance data environment.
Technical Mastery: Expert-level Python skills; familiarity with the numerical stack (Pandas, NumPy, SciPy) and production-standard software engineering practices.
Domain Knowledge: A solid grasp of Fixed Income mechanics—specifically interest rate curves, credit spreads, and fixed-income derivatives.
Analytical Skills: Ability to handle large-scale market data and an understanding of how risk models function within a multi-asset portfolio.

Expert Analysis

In 2026, the Fixed Income Quant space is being reshaped by Electronic Trading (e-Trading) and Credit Systematic Alpha. This role is particularly valuable because it combines “macro” product knowledge with high-end engineering. Candidates who can demonstrate an understanding of Yield Curve Construction or Credit Default Swap (CDS) pricing within their code will have a significant advantage in the interview process.

Location & Logistics Guide

The role is situated in London, likely in the financial corridors of Mayfair (Home to many hedge funds) or the City of London. These areas provide the world’s most dense ecosystem of quant talent and are accessible via major hubs like Liverpool Street or the Elizabeth Line.
