Alexa Science | Data Scientist | Cambridge, MA | ONSITE, FULL TIME 
As a Sr. Data Scientist in our Applied Modeling and Data Science team, you will be responsible for data-driven improvements and evaluation for our spoken language understanding models. Your work will directly impact our customers in the form of products and services that make use of speech and language technology.
The Alexa Science and Machine Learning team made the magic of Alexa possible, but that was just the beginning. Our goal is to make voice interfaces ubiquitous and as natural as speaking to a human. We have a relentless focus on the customer experience and customer feedback. We use many real-world data sources including customer interactions and a variety of techniques like highly scalable deep learning. Learning at this massive scale requires new research and development.
