Alexa Connections is on a mission to become the world's most trusted communication agent — spanning calls, text, email, and the ever-expanding surfaces where people connect. We're building intelligence that keeps customers connected effortlessly while putting their trust and privacy first. As an Applied Scientist, you'll help build the smartest communications agent for people — an agent that understands intent, context, and relationships, and that acts on a customer's behalf to make every interaction feel effortless and genuinely helpful
Key job responsibilities
You'll research, develop, and ship ML and AI solutions across the communication experience, reasoning over conversational context, intent and needs, and orchestrating large language models and agentic workflows that anticipate how, when, and with whom customers want to connect, and then get it done on their behalf. Whether it's surfacing the right message at the right moment, drafting a reply that sounds like the customer, remembering who matters most to them, or seamlessly carrying a conversation across calls, text, and email, you'll tackle ambiguous, open-ended problems at the intersection of applied science and real-world communication, turning advanced research into features that keep people effortlessly connected to the ones they care about.
About the team
We're building up the Alexa Connections science team, so you'll join early and grow alongside it. You'll work closely with experienced scientists and engineers invested in your development, with plenty of mentorship, room to broaden your skills, and the chance to own meaningful problems as you grow. It's a supportive place to do impactful work early in your career, shaping how millions of customers connect every day.
