We believe that we are better together, and at Tripadvisor we welcome you for who you are. Our workplace is for everyone, as is our people powered platform. At Tripadvisor, we want you to bring your unique identities, abilities, and experiences, so we can collectively revolutionize travel and together find the good out there.

Tripadvisor is looking for an exceptional scientist to join our Machine Learning Team, focusing primarily on the Tripadvisor Experiences business. Our Experiences vertical provides customers with a collection of over 300K bookable products - experiences like glacier hikes in Alaska, guided walking tours in Lisbon, swimming with pigs in the Bahamas, and many, many more. The fast-growing user and product spaces pose a significant challenge for us: how to match users with experiences that are relevant to them, particularly in international markets where we hope to grow our footprint even further. As a Machine Learning Scientist working in this space, you will have the opportunity to apply your modeling and engineering skills to a number of different areas, but with a particular focus on sort and recommendations. You will have access to the newest development tools and huge data sets. You will deploy your solutions online and be able to observe the impact of your work in real time as you help the company grow.

We are looking for someone who is independent, curious, and motivated; who likes discussing ideas and will bring something new to the table. You will be working in a diverse environment where you’ll collaborate with a broad multidisciplinary team of ML scientists, analysts, software engineers, and product managers. You’ll be encouraged to take ownership of your projects and to find new opportunities and problems where machine learning could be applied to improve the business. Finally, you will also be provided the environment to grow technically and personally into a leader while contributing to the team.
