Job description

The Source domain consists of roughly 30 people ─ software engineers, data analysts, and project owners ─ working in interdisciplinary teams in four different tech areas. Together we are responsible for ingesting, matching, consolidating, and delivering the accommodation to our product development teams. We are building the foundation of our platform and helps millions of daily users find their ideal hotel at the best rate.

Amazon SageMaker is empowering our Data Scientist to build, train and deploy models aiming for better matching performance.
