Contract Description

Senior Machine Learning/ Data Scientist


Contract initially 4 months

Position Summary: We are currently seeking a highly motivated expert in machine learning for our EY Brain Team. The team is developing predictive models for the capital markets. Yet we don 't expect you to be proficient in capital markets.

We need people who can identify appropriate modelling techniques to answer the most critical business questions and use this analysis to infer well substantiated business insights in predicting transactions on financial markets. Your portfolio of skills covers a wide range of machine learning techniques and advanced statistical techniques for classification, feature selection, scoring methods, recommendations, forecasting, as well as data management, data visualization, and optimization, applied in a commercial context. The ideal candidate will be passionate about artificial intelligence and stay up-to-date with the latest developments in the field.

You will,

  • Develop machine learning models, natural language processing and statistical analyses
  • Develop and analyse the algorithms that could be used to solve a given problem and rank them by their success probability
  • Retrieve, prepare and process data from a variety of sources
  • Analyse large datasets of numeric and text values
  • Use vast data sources available in-house and research for additional external sources
  • Explore and visualize data to gain an understanding, identify differences in data distribution
  • Define validation strategies
  • Explain rationale behind decisions made to choose algorithms and how the algorithms achieve the results
  • Present results of modelling and options for future direction
  • Understand business objectives and develop models that help to achieve them, along with metrics to track their progress
  • Build valued relationships with internal peers and external clients and contribute to the development of business direction.
