Software Development Engineer, Alexa Smart Home

We are looking for a Software Development Engineer that will help us evolve Alexa into the AI assistant of the future by helping build, train, and deploy modern AI models. The Smart Home team is focused on making Alexa the user interface for the home. From the simplest voice commands (turn on the kitchen light or turn down the heat) to more complicated and natural use cases that use the power of AI and LLM, such as “Turn on the new light in my office” or “Turn off all the lights, except the living room if the TV is on”. We are evolving Alexa into an even more intelligent, indispensable companion that automates 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. And, you will have the satisfaction of working on a product your friends and family can relate to, and want to use every day.

The key unique challenge in the Smart Home domain is that the interpretation of all utterances is dependent on the device context of the home. This is the collection of all smart home and Echo devices that a customer owns, along with the names and grouping of those devices, as configured by the customer. This means that for the same utterance ("Turn on the lights"), a different device context results in different correct actions, such as turning on a single light, all lights, or a smart plug. Solving the problem takes on complexity in these two dimensions, which we call utterance complexity and customer complexity.

Key job responsibilities
- Build, deploy, and maintain Native AWS infrastructure to enable AI model training and inference for both online customer experiences and offline evaluation.
- Create services to enable language engineers to effectively and efficiently annotate utterances for complex use cases.
- Design solutions to challenging model training, inference, and evaluation problems at Amazon scale.
- Support operational excellence initiatives.

About the team
We are a team of Machine Learning Engineers and Software Developers, who are part of the Smart Home AI group. We work together to make Alexa more insightful and proactive through ambient intelligence - with features like Alexa Hunches that automatically control Smart Home devices.

We are interdisciplinary and we act like it -- we ask each other questions and value our different perspectives. The AI technology revolution has created new opportunities to add more intelligence to our customers lives. With multi-year roadmaps planned across all Alexa domains, Smart Home is one of the pioneers of LLM adaptation. We are looking for a SDE who will help us to build algorithmic platforms and tools required to evolve Alexa into the AI assistant of the future.
