Head of Data Science

Operations Strategy Lisbon, Portugal


Description

THE ROLE

We are looking for someone who wants to help set the standard in data science for operations.

We solve complex problems with carefully defined approaches backed by data, and get to see the outcome of the implemented solutions impacting hundreds of employees and millions of customers.

In particular, Operations in Farfetch includes our global Supply Chain with millions of orders and thousands of routes, and our product imagery and descriptions, which we aim to continuously improve and optimize. With that purpose, we leverage large volumes of structured and unstructured data - in the form of both images and natural language - by applying state-of-the-art machine learning/deep learning and operations research techniques, against a wide spectrum of problems.

While we have many projects in delivery, we also keep a heavy focus on research, so that we always know what the best solution for a given problem is.

We are looking for someone who is a self-starter, with relevant experience successfully leading teams and developing people.

WHAT YOU'LL DO

  • Hire, coach, and lead a team of talented data scientists to deliver value;
  • Develop each data scientist in order to achieve A+ performance, motivation and happiness;
  • Define your team’s roadmap in partnership with business and technology partners;
  • Identify opportunities to improve the customer experience driven by operations;
  • Identify opportunities to automate operations;
  • Engage with our technology partners (e.g., data engineers, infrastructure) to refine the road to production;
  • Communicate complex solutions in a clear and understandable way to both experts and non-experts.
