The firm specializes in building sophisticated execution algorithms and transaction cost modeling tools servicing multiple asset classes. The firm provides its services to performance-demanding hedge funds, CTAs, asset managers, and banks through a traditional electronic broker and in a broker-neutral Software as a Service (SaaS) model.

BestEx Research’s mission is to become the leader in automation and measurement of execution across asset classes globally and significantly reduce transaction costs for our clients.

Your Role

As a Quantitative Researcher, you will be a key contributor to the team responsible for our core research ecosystem. You will work alongside experienced practitioners to develop rigorous quantitative models, design robust analytical frameworks, and drive the mission-critical research that powers our algorithmic trading strategies using tick-by-tick market data and execution logs. This is an opportunity to contribute to scalable, high-impact research within the high-stakes environment of algorithmic trading.

At BestEx Research, our quantitative researchers are deeply integrated into the full research lifecycle from hypothesis generation through model validation and production deployment. You will develop a specialized understanding of global market microstructure, algorithmic execution, and performance measurement. Our researchers are nested within a talented team of experts and practitioners in the field and regularly contribute to writing research papers, while interfacing closely with client research teams to improve trading costs and execution quality. Your day-to-day responsibilities in this role can include, but are not limited to:

What You’ll Work On

  • Design, develop, and validate quantitative models for market analytics and transaction cost analyses.
  • Conduct rigorous statistical analysis on large, complex datasets to surface actionable insights
  • Partner with engineers to bring research prototypes into production systems
  • Define and track model performance metrics. Monitor deployed models for drift and degradation
  • Contribute to a culture of intellectual rigor by peer-reviewing analyses, documenting methodology, and sharing findings across teams
  • Stay current with academic research and industry developments; evaluate applicability to company problems

Requirements

You Should Have

  • A highly motivated self-starter mindset with the ability to take end-to-end ownership of research work.
  • Advanced degree (MS or PhD) in a quantitative field (Mathematics, Statistics, Economics, Physics, CS, or related) preferred, or equivalent demonstrated experience.
  • Expert in Python (Numpy, Pandas, scikit-learn, statsmodels)
  • Strong foundation in statistics, probability, and machine learning.
  • Demonstrated ability to take a research question from problem definition through model deployment.
  • Clear written and verbal communication - you can explain a model's assumptions and limitations to a non-technical stakeholder

Bonus Points For

  • Experience - 5+ years
  • Familiarity with R for research and visualization.
  • Prior experience (0-5 years) in fintech, electronic trading, or a data-heavy research environment is highly valued.
  • Prior exposure to real-time or production ML systems.
  • Exposure to AI is a big plus

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
