Senior Machine Learning Scientist

The Traveler Recommendation Data Science team is a geographically distributed team across Austin, Seattle and London offices with a good composition of junior and senior of 11 machine learning scientists. The mission of the team is to build state of art algorithms to help our travelers to find the right traveling Product that fit their needs. Our AI algorithms powers recommendations on hotels, vacation rentals, car, destinations, air, activity and packages.

This role is for a Machine Learning Scientist to join our fast-growing Machine Learning Science team. We create and innovate state-of-the-art machine learning algorithms to make our recommendation platform more effective and efficient, increasing its relevance for travelers worldwide. We collaborate closely with the engineers, product, and other data science teams to create the top-notch recommendation platform in the traveling industry.

What you’ll do:

  • Build a scalable, real-time, in-session personalization recommender systems drive various personalized recommendation scenarios.

  • Implement and compare supervised learning models (e.g. LR, GBDT and DNNs, RNNs) or transformer, embedding, ensembles of models, to improve metrics often with multiple contending objectives (i.e. relevance, degree of personalization, average value of booking, gross profit).

  • Develop brand-new learning frameworks for multiple carousels ranking and whole page optimization.

  • Take end to end ownership of large and scalable machine learning systems – from data pipelines, feature engineering, candidates' extraction, model training as well as integration into our production systems.

  • Incorporate the latest academic and published research including neural network, transformers and reinforcement learning domains.

  • Work closely with product managers, data scientists/engineers and designers on product teams to offer item recommendations for millions of users.

Communication and presentation:

  • You will build clear, concise and well-structured functional material (e.g. policies & and procedures, guidelines, presentations, messages) and recommend improvements to existing material.
