Tripadvisor is looking for an experienced Senior Software Engineer to join our Find & Discover Team. This team builds foundational search, taxonomy, natural language processing and other capabilities for the Tripadvisor website and app. These capabilities are expressed as both user facing features as well as core services consumed by other product and engineering teams. 

Our users are looking for guidance and advice across all parts of the travel planning and in-destination experience.  Our team aims to answer the aspirational: "show me anywhere in the world, I just want a life-changing experience", to the task-oriented: "help me plan the best possible trip to Belize, I love diving!", to the here-and-now: "I’m going to Chicago for a wedding next week, what’s good this time of year?"

We spend our time obsessing over the hundreds of millions of unique monthly users of our products and how they can make the most of their time with us, so that they can find the right hotels, restaurants, experiences and more that will make for the best trip possible. Successful members of our team have a passion to positively impact our users, and actively seek out that opportunity from day one. Working in partnership with Product Management, Design, Machine Learning, and Platform Infrastructure teams, you will deliver solutions that scale to our community, that showcase our experience, and of which you can personally be proud. We move quickly, we iterate constantly, and we’re not afraid of setting big goals for ourselves.
