Job Description

Role Overview

A premier High-Frequency Trading (HFT) firm is seeking a proactive Quantitative Researcher to join their core Latency group in London. In this specialized role, you will apply advanced data science and statistical methodologies to interrogate billions of trading data points, uncovering the micro-edges that define competitive success in automated markets.

This position bridges the gap between high-level business metrics and the underlying infrastructure technology. You will work side-by-side with trading teams to perform post-trade statistical audits, identifying how technological shifts impact execution quality. Beyond analysis, you will be responsible for the investigation and architectural design of proprietary data mining and machine learning algorithms. This global organization maintains the agile, high-energy environment of a start-up while providing the institutional security of an industry leader, making it an ideal destination for an independent researcher who thrives on driving complex projects from conception to production.

Key Responsibilities

Latency Analysis: Analyze massive datasets of historical trading events to pinpoint bottlenecks and identify relationships between system performance and business PnL.
Algorithm Design: Research and develop innovative machine learning and data mining algorithms to detect patterns in high-frequency market data.
Post-Trade Research: Conduct rigorous statistical analysis on execution data to provide trading teams with actionable insights for strategy optimization.
Cross-Functional Collaboration: Partner with infrastructure and trading engineers to understand the impact of hardware and network changes on alpha generation.
Project Leadership: Independently drive research initiatives, ensuring that discoveries are translated into technical requirements or trading enhancements.

Requirements

Experience: Minimum of 2+ years of professional experience in a quantitative research or data science role (Note: Not open to fresh graduates).
Programming Mastery: Expert-level Python skills, with a heavy emphasis on data science libraries (Pandas, NumPy, Scikit-learn).
Statistical Depth: Strong foundation in probability, statistics, and machine learning theory.
Problem-Solving: Exceptional analytical abilities and a curiosity for exploring massive, noisy datasets.
Technical Bonuses: Familiarity with C++, SQL, and network protocols (TCP/IP, UDP, Multicast) is highly advantageous.
