We tackle the most complex problems in quantitative finance, by bringing scientific clarity to financial complexity.

Join a research team where curiosity meets scale. You’ll investigate foundational questions, uncover market insights and push the boundaries of what's possible - all with the support of near-limitless compute and world-class peers.

Take the next step in your career.

The role

  • 10-week summer programme (21st June - 27th August 2027)

Our business is to predict the future of financial markets, applying scientific techniques to find patterns in large, noisy and rapidly changing datasets. Our mission as a Data Science team is to help discover, enrich and analyse data sources that will drive tomorrow’s research initiatives.

This is a team at the forefront of the company’s data strategy, responsible for finding solutions to some of the many important data challenges within the firm, meaning you will have a unique opportunity to make an impact from the beginning. The successful candidate will be comfortable working within a multi-disciplinary team, collaborating with industry leading data scientists and financial experts, developing solutions that adapt to a rapidly changing data landscape.

The role will offer exposure to cutting-edge technologies in a high-growth industry, with opportunities to learn about multi-asset class systematic investing and big data development in an innovative and forward-thinking firm.

  • A current undergraduate, master's or PhD student in a quantitative subject
  • Strong critical thinking skills and exceptional problem-solving ability
  • Comfortable applying statistical concepts to real-world data
  • Experience using Python, including for exploratory data analysis and visualisation
  • Strong communication skills

The following would also be beneficial:

  • Active Git Hub or Kaggle profiles
  • Experience selecting, developing and refining machine learning models
  • Knowledge or interest in natural language processing
  • Demonstrable proficiency in statistical data analysis

Why should you apply?
