Software Development Engineer, Alexa Connections

Do you want to shape how people stay connected across calls, text, and email? Alexa Connections is building a trusted communication agent that understands intent, context, and relationships, then acts on a customer's behalf to make every interaction feel natural. As a Software Development Engineer on this team, you'll design and deliver the software systems behind a context-aware assistant that grows more helpful over time. You'll work across the full software development lifecycle — from understanding customer problems, through system design and implementation, to deployment and operations — building privacy-first solutions that serve tens of millions of daily communication events. Key job responsibilities - Design and implement software services that model each customer's personal connections graph, a privacy-first representation of relationships and communication patterns used to power context-aware assistance. - Build and operate scalable backend systems that integrate large language models and agentic reasoning to anticipate who, when, and how a customer wants to connect across calls, text, and email. - Collaborate with scientists, product managers, and peer engineering teams to translate research advances in personalization and memory into reliable, production-grade features. - Contribute to the full software development lifecycle — scoping, design, code review, testing, deployment, and operational support — while coaching teammates through constructive code reviews and documentation. - Identify and resolve root causes of operational issues, and continuously improve system reliability, maintainability, and performance. A day in the life Your morning might start with a design review for a new personalization feature, working through tradeoffs in scalability and data privacy with senior engineers and applied scientists. After lunch you could be writing and testing code for a service that ranks a customer's most relevant contacts, then pairing with a teammate on a code review. You'll regularly join standups with product managers and scientists to align on priorities, and you'll rotate through on-call responsibilities to keep the systems you build running smoothly.
