I recruit front office quants, strats & researchers | Sell-Side & Buy-Side

Join a High-Performing Front Office Quant Team – London-Based Opportunity - Associate Director level - base up to £170k

I’m partnering with a leading global investment bank looking for an experienced Quant Analyst with deep expertise in interest rates, yield curve calibration, and classical pricing models to join their front office quant team.

This is a hands-on role focused on Fixed Income and Rates , working closely with trading desks, risk, and finance teams to support pricing, risk, and model integration across FX, Rates, Credit, and Equities.

You will be implementing models directly in a front office C++ library (not just using others’ code), so strong C++ skills and familiarity with the full model implementation path are essential.

What You’ll Do

Build and enhance quantitative models using C++11+ , focusing on interest rate curve construction and modernization of FX and rates libraries
Partner closely with trading desks to develop and implement models for pricing and structuring, challenging traders where appropriate
Design, test, and document production-quality model workflows to enterprise standards
Maintain and improve a high-quality codebase and testing framework
Collaborate with other teams on flow rates and structured rates, with experience in exotic rates considered a plus
Support the operational front office function with hands-on involvement in curve construction and modeling

What We’re Looking For

Strong front office quant background, with deep expertise in interest rates, yield curve calibration , and classical quantitative finance (stochastic calculus, PDEs, no-arbitrage valuation, numerical analysis)

Proven experience implementing models in a front office C++ library (C++11+), not just using implementations from other teams

Familiarity with Python, Excel , and version control systems (e.g., Git)

Experience working in or with investment banking quant teams , ideally in a front office or trading desk support role

Strong relationship builder, able to challenge traders and collaborate effectively across multiple teams

Operational mindset with a practical approach to model implementation and production support

Experience or knowledge of exotic rates products is a plus

Flexible working environment with up to 3 days per week in the London office

Ideal for experienced quant with deep domain expertise and those who want a meaningful, hands-on role in a top-tier investment bank.

If you’re a quant analyst ready to take ownership of front office model implementation and work alongside a world-class team, let’s connect.
