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.

The role will involve:

- 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
Essential experience:
- Hands-on experience with search ranking / search order / sort order
- Hands-on experience with recommendation / recommender systems
- Strong Python and SQL
- Snowflake
- AWS
- Strong A/B testing / experimentation
- Experience measuring ranking or recommendation changes against commercial KPIs
- Strong hands-on Data Science background
Nice to have:
- Learning-to-rank / re-ranking
- Metaflow
- XGBoost / LightGBM
