• Translate business problems into analytical problems and develop models aimed at solving our clients’ and users’ problems and ensure they are evaluated with the relevant metrics.
• Write highly optimised code to advance our internal Data Science Toolbox.
• Add real‑world impact to your academic expertise, as you are encouraged to write papers and present at meetings and conferences should you wish.
• Take part in R&D projects; attend conferences such as NIPS and ICML as well as data science retrospectives where you will have the opportunity to share and learn from your co‑workers.
• Work in one of the most advanced data science teams globally.
• Work on the frameworks and libraries that our teams of data scientists and data engineers use to progress from data to impact.
