About the Role

We are looking for a Machine Learning Engineer to join our London office - a fast-growing start-up environment within international commodity trading. This role will be working closely with our Front Office traders - applying machine learning, statistics and programming skills to yet-to-be-solved problems.

This role provides exposure to innovative projects, complex modelling and the chance to work on ever-changing challenges and priorities. If you embrace challenges and are keen to apply your technical skillset and passion to real-life trading models, then we want to hear from you!

This will be a full-time permanent role, owning the following responsibilities:

  • Research and develop systematic trading ideas, by deploying cutting-edge data science tools on noisy and changing financial time series.
  • Work closely with traders and fundamental analysts in order to understand and analyse data.
  • Work with statistics to test hypotheses and evaluate outcomes.
  • Implement and back test new trading strategies, building components of our research platform and analytics libraries.


About You

This person will be highly data-driven, autonomous and comfortable owning complex statistical projects solo.

In addition, we are looking for somebody with the following:

Essential Requirements:

  • A minimum of 3 years' experience working on financial time series data.
  • A Master’s degree in Computer Science, Statistics, Mathematics or a similar related technical field. A PhD or other doctoral degree in a related technical field is preferrable.

  • Strong Python experience and working knowledge of data analytics.
  • Ability to undertake research and implement best practices as required.
  • A background in machine learning frameworks such as TensorFlow is desirable but not essential.

Other Attributes:

  • Ability to thrive in a fast-paced trading environment.
  • Fluent English language skills.
  • Ability to translate highly technical concepts into practical terms and application.
  • A commercial mindset and understanding of how to apply machine learning to real-life trading strategies, or willingness to develop this.
  • Analytical and highly numerate, with strong attention to detail.
  • Ability to communicate and collaborate effectively across different levels of the global business.
