The role

I'm working with a major consumer travel business looking to bring in a hands-on Data Scientist to support a project focused specifically on search order, ranking and recommendation.

The business manages a large inventory of holiday properties, and the core problem is deciding which properties should appear, in what order, for a given customer search.

This is not a generic Data Science role. Previous experience with search ranking / sort order / recommendation systems is essential.

What you'll do

  • Improving the search order / ranking logic used to surface properties to customers
  • Building and refining recommendation and ranking models
  • Working across ranking by destination, country, brand, park and individual property / unit level
  • Running A/B tests and experiments to measure the impact of ranking changes
  • Measuring performance against customer and commercial KPIs
  • Analysing how factors such as price, brand, region and country affect sort order performance
  • Building out a broader dashboard / KPI framework
  • Working with behavioural and transactional data
  • Feeding findings and recommendations back to product and business stakeholders
