Software Development Engineer III, Alexa Connected Devices

Imagine building the intelligent bridge between millions of Alexa-enabled devices and Alexa Cloud — services that handle tens of billions of transactions per day, where every millisecond matters. Now imagine doing it at a moment when AI is fundamentally reshaping what that bridge can do. That's the opportunity waiting for you on the Alexa Connected Devices team!

We are looking for a passionate engineer to work on the development of Tier-1 services for Alexa Cloud that power customer-facing experiences across domains — from audio and video to smart home, shopping, and beyond. You'll play a key role in integrating AI-driven capabilities into these experiences — from intelligent personalization and predictive interactions to AI-augmented development practices that accelerate how we build, test, and ship software.

• Build low-latency, low-cost, highly reliable, and highly scalable connectivity services between Alexa-enabled devices and Alexa Cloud
• Design and integrate AI components into connectivity services, evaluating trade-offs across latency, cost, reliability, and accuracy
• Drive and lead software design, development standards, team processes, and code reviews
• Leverage AI-augmented development tools to accelerate design, coding, testing, and debugging workflows
• Deliver high-quality software through working in a dynamic, team-focused Agile/Scrum environment
• Contribute to the professional development of colleagues, improving their technical knowledge and engineering practices — including adoption of AI-first development practices

• Monitor and own the operational health of Tier-1 services processing tens of billions of transactions daily
• Design and build AI-powered, customer-facing features that span domains like smart home, audio, shopping, and more
• Collaborate with partner teams across Alexa — device engineers, ML scientists, and product managers — to deliver end-to-end experiences
• Use AI-augmented tools and practices to ship faster and raise the bar on engineering quality
• Mentor teammates and drive adoption of AI-first development across the team

The mission of the Alexa Connectivity team is to deliver low-latency, low-cost, highly reliable, and highly scalable connectivity between Alexa-enabled devices and Alexa Cloud. The changes we make improve the speed and reliability experienced by end customers when interacting with Alexa devices, and simplify the experience for developers and the rest of Alexa by abstracting connection management from them. The team handles tens of billions of transactions per day.

We are increasingly an AI-first team — embedding intelligence into our services and our development lifecycle. This is a highly visible role to get in at the inception phase, build new AI‑enhanced features, and operate a Tier‑1 Cloud Service. The ideal candidate is excited about the incredible opportunity that Alexa and Cloud represent, and is passionate about delivering high‑quality services in a hyper‑growth environment where AI is a core accelerator.
