Data Scientist, Alexa Smart Home SLU

Reference ID: 716289

Share job:

The Smart Home team is focused on making Alexa the user interface for the home. From the simplest voice commands (turn on the lights, turn down the heat) to use cases spanning home security, home entertainment, and the home environment, we are evolving Alexa into intelligent, indispensable companion that automates daily routines, simplifies interaction with appliances and electronics, and alerts when something unusual is detected.

You will be part of a team delivering features that are highly anticipated by media and well received by our customers. Here are a few links that highlight working with Alexa.

How to make the Amazon Echo the Center of Your Smart Home:

As a Machine Learning Scientist, you will work with software developers and other teams to design and implement NLU models for how customers use and interact with smart devices in their homes. You will help lay the foundation to move from directed device interactions to learned behaviors that enable Alexa to proactively take action on behalf of the customer. And, you will have the satisfaction of working on a product your friends and family can relate to, and want to use every day. Like the world of smart phones less than 10 years ago, this is a rare opportunity to have a giant impact on the way people live.
