Equity Finance Quantitative Strategist — VP/SVP

Equity Finance Quantitative Strategist — VP/SVP

Jefferies LLC | New York, NY | Securities Finance

The Opportunity

Join a high-impact, entrepreneurial quant team embedded directly within the Equity Finance trading desk. You will own the full lifecycle of quantitative models — from research and prototyping through production deployment — that directly drive P&L, optimize financial resource consumption, and give our clients a differentiated analytical edge. You will own the full quantitative model suite across equity swaps, securities lending, custom baskets, and prime brokerage — spanning liquidity management (ALM/MLO), valuation, counterparty risk, client analytics, factor-driven portfolio solutions, and hard-to-borrow pricing/locates.

Unlike large-bank quant factories, this role offers direct partnership with senior traders, visibility to desk leadership, and the autonomy to shape the analytical direction of a rapidly growing business. You will work directly with clients on bespoke portfolio solutions and build systems that traders use every day to make real-time decisions.

You will be part of a Global Quant team spanning New York and London, collaborating closely to ensure alignment on strategy, shared tooling, and state-of-the-art quantitative capabilities across regions.

What You Will Own

Quantitative Modelling & Analytics

Design and implement pre-trade optimization models for funding, liquidity risk, and tenor mismatch — driving measurable P&L improvement

Build factor analytics engines, custom basket construction tools, and risk decomposition frameworks for equity swap and securities finance portfolios

Develop forward funding rate projection models and collateral optimization algorithms

Create P&L attribution, risk factor analysis, and scenario modelling across Equity Swaps and Securities Finance

Liquidity Modelling.

Client-Facing Analytics & Custom Solutions

Partner directly with hedge fund and institutional clients to design and optimize custom basket strategies — portfolio construction, factor tilts, and rebalancing logic

Develop bespoke quantitative tools that help clients analyze their portfolio exposures, optimize execution, and manage risk

Serve as a technical counterpart to clients on complex structured and systematic strategies, translating their investment objectives into quantitative implementations

Build analytics that surface client flow patterns, profitability drivers, and resource consumption (balance sheet, capital, funding) at a granular level

AI, Machine Learning & Intelligent Automation

Apply machine learning techniques (gradient boosting, NLP, clustering) to identify patterns in client flow, predict funding demand, and optimize inventory positioning

Leverage large language models (LLMs) and generative AI to automate research workflows, extract insights from unstructured data, and build intelligent decision-support tools for the trading desk

Develop AI-powered automation pipelines that eliminate manual processes — from data ingestion and reconciliation to report generation and anomaly detection

Build and maintain agentic AI systems that augment trader workflows, including automated monitoring, alerting, and recommendation engines

Technology & Architecture

Architect scalable, production-grade Python systems on a modern, greenfield infrastructure stack — no legacy systems, no tech debt to inherit

Build on AWS-native infrastructure (S3, Redshift, Lambda, Airflow/MWAA) purpose-built for quantitative finance workloads

Leverage Claude Code as the primary development environment — AI-assisted coding end-to-end, from prototyping through production deployment

Access custom-built global AI agents developed by the team that provide a best-in-class developer experience: automated testing, code review, deployment pipelines, and intelligent tooling that accelerates every stage of development

Build interactive dashboards and real-time analytics platforms used daily by the trading desk

Own the full development lifecycle: research → prototype → production → monitoring

Global Quant Team Partnership

Collaborate with London-based quants on shared models, analytics infrastructure, and tooling

Contribute to and benefit from a shared quantitative library and reusable component ecosystem

Participate in cross-regional knowledge sharing — what is built once is deployed globally

Lead and define technical roadmap alongside global leadership
