Description
Alexa is looking for an Applied Scientist with a strong background in Natural Language Processing (NLP) and Large Language Models (LLMs) to help build state-of-the-art conversational systems.
In this role, you will collaborate with a large team of scientists training the Large Language Models that power the Alexa stack, as well as software engineers serving them in production systems. You will own solutions end-to-end: from ideation and research through to production deployment, enabling conversational assistants to support external tools, leverage diverse sources of information, and deliver novel reasoning capabilities to millions of Alexa customers.
Key Job Responsibilities
As an Applied Scientist, you will:
- Develop innovative solutions to complex problems to extend the functionalities of conversational assistants.
- Use your technical expertise to research and implement novel algorithms and modelling solutions in collaboration with other scientists and engineers.
- Analyze customer behaviors and define metrics to enable the identification of actionable insights and measure improvements in customer experience.
- Communicate results and insights to both technical and non-technical audiences through written reports, presentations and external publications.
- Be able to bi-modal on science and engineering: someone who combines strong scientific foundations with the execution skills to ship high-quality solutions.
