The Alexa Customer Journeys team is seeking a Language Data Scientist with experience in the field of Natural Language Processing, Machine Learning, or Large Language Models, as well as expertise in handling large data sets and strong analytical skills. You will play a critical role in innovative projects by driving design of Alexa features. The key responsibilities are to generate high-quality data and to run and evaluate experiments, which involves prompt engineering our Large Language Model for API delivery. You will work closely with engineers, scientists, and program managers to ensure we're providing the best Alexa experience for millions of our customers.

As a Language Data Scientist, you will start by diving deep into a couple of critical projects across Alexa experiences . You will collaborate with fellow Language Data Scientists, Program Managers, and stakeholders in science, engineering, and product teams to understand the role data plays in developing data sets and exemplars that meet customer needs. You will analyze and automate processes for collecting and annotating LLM inputs and outputs to assess data quality and measurement.

You will apply state-of-the-art Generative AI techniques to analyze how well our data represents human language and run experiments to gauge downstream interactions. You will work collaboratively with other Language Data Scientists to design and implement principled strategies for data optimization.
