<title>About the role</title>

<text>

As a Staff Data Scientist, you’ll develop forecasting models to predict the short- and long-term impact of incentives on business growth. You’ll also use optimization techniques to distribute incentives over different periods, cities, and channels to maximise business growth.

You’ll be responsible for building products powered by Data Science models that internal teams can use for portfolio planning and budgeting. In addition, you’ll work on decomposing and modelling business growth into interpretable and actionable components.

As a Staff level Data Scientist, you will coach less experienced team members by sharing good practices in problem-solving, modelling, software engineering and soft skills.
