  • Practical experience in relevant machine learning and data modelling techniques used in supervised problems such as decision trees, Random Forests, Gradient boosted machines, linear/logistic regression, deep learning, or unsupervised problems such as clustering and dimensionality reduction. All involving complex/high-dimensional data (e.g. image, text, video, speech, time series).
  • The ability to work collaboratively and proactively in a fast-paced environment interacting with both a non-technical and technical audience.
  • A good understanding of graph databases
  • Interest in using ML to drive a meaningful impact to the consumer experience and business.
  • Expertise in one or more programming/scripting languages (e.g. Python, R, Matlab)
  • Good ability to interpret business requirements, translate into data science problems and deliver high value outputs.
  • Ability to work quickly and iterate through trial-and-error, rather than spending an excessive amount of time designing the most robust methodology to deploy at the outset
  • Ability to make data tell a story through data presentation / visualisation tools and techniques
  • Research new data modelling, machine learning and data mining techniques for application across functions such as recommender systems, optimisation, time series forecasting, uplift evaluation and AB testing, Natural Language processing, computer vision, clustering and segmentation.
  • Research and evaluate new datasets like clickstream, geo-location, market research, contextual, undertaking data discovery and exploration to identify opportunities to develop strategies and techniques to improve results.
  • Leverage state-of-the-art big data tools (such as Spark, Python, R) and techniques to build innovative solutions using appropriate modelling techniques and data sets with a focus on implementation.
  • Develop and embed improvements to data science processes, in particular around building, deploying and monitoring.
  • Explore different ways for data visualisation.
  • Look creatively at our data challenges and map out the best approaches to tackle them using the state of art machine learning.
