Software Development Engineer II, Alexa 3P Experiences

Alexa+ is Amazon's next-generation personal assistant powered by generative AI – more conversational, smarter, personalized, and built to get things done on any device.
The Alexa 3P Experiences team is on a mission to expand what Alexa+ can do for customers by building consumer-facing experiences with trusted third-party partners like Uber, Ticketmaster, Yelp, and more. Using frontier AI technologies – including Large Language Models (LLMs), Model Context Protocol (MCP), and Agent-to-Agent (A2A) capabilities – we create agentic experiences that connect customers with an ever-expanding selection of services through natural conversation.
As an SDE II on this team, you will design and build category-defining experiences that millions of customers interact with daily. You will work closely with product, design, and partner teams to deliver high-quality, scalable solutions that drive customer discovery, engagement, task completion, and monetization. You will contribute to category scaling frameworks – reusable components that enable partners to build sophisticated experiences with minimal effort.
We're a team that moves fast, builds with AI-native technologies, and measures success by customer impact. If you want to work at the intersection of generative AI and consumer experiences, this is the place.

A day in the life
A typical day will start with a morning huddle to catch up on what you and your team worked on the previous day. This is usually followed by some whiteboard design discussions on the problems the team is working on. The afternoon is mostly spent on project design and implementation work with a heavy dose of code reviews from and for your team along the way. We are a fun, close-knit team where everyone is ready to roll up their sleeves and help each other out, push boundaries, and have fun doing it!
