• Proactively acquire data from various sources and analyse it to improve data quality and understanding for desired application

• Tell engaging stories using simple language and exciting visualisations to influence change and explain complex concepts to non-technical audience

• Execute experiments to quantify the performance of your algorithms in both digital and physical domains and test business hypotheses

• Support and advise on the creation of productionised solutions by Agile development teams on a Hadoop/Spark/Python stack to support the team strategy

• Proactively engage with the business and engineering functions (and cross-functionally) to investigate and define possible applications of data to business problems in a way that can drive tangible benefits
