Software Development Engineer, Devices Software & Services
About the role
The Amazon Devices Software & Services team is looking for a Software Development Engineer to join a high-velocity, specialized team. This is not a traditional framework or infrastructure role - we are building a new groundbreaking customer experience that will define how millions of users worldwide interact with their technology - making it more proactive, intuitive, and invisible. We're building the systems that put AI into production — the runtime, services, and tooling that turn large language models and autonomous agents into reliable, safe, scalable products.
What you'll do
- Invent New Paradigms: Move beyond traditional voice UI to build "Ambient Intelligence" experiences that span Alexa, Fire TV, and mobile/wearable surfaces, focusing on proactive assistance rather than reactive commands.
- Rapid Innovation: Operate in a fast-paced environment where you will prototype, test, and deploy features that leverage multimodal inputs (camera, audio, and documents) to create personalized customer magic.
- Cross-Surface Continuity: Ensure that a customer's experience is persistent and context-aware beyond the device boundaries - whether they are at their desk using Alexa.com, in their living room with Fire TV, or on the go with a wearable.
- Design, build, test, and operate scalable backend services and libraries that power AI/LLM-driven features.
- Integrate and harden model providers, tools, and agent capabilities behind clean, versioned interfaces — with sane failure behavior, observability, and cost/latency awareness.
- Build evaluation and regression tooling so AI behavior is measured, gated, and trustworthy — not vibes.
- Apply security-conscious, fail-closed design to anything touching credentials, user data, tool execution, or autonomous actions.
- Work fluently alongside AI coding assistants: decompose tasks an agent can execute, critically review AI-generated code, and keep engineering rigor high at AI speed.
About the team
We're a platform team that builds the shared AI/agent infrastructure used across multiple products. We care about correctness, safety, and developer experience in equal measure. We operate test-first, review adversarially, keep our core clean and reusable, and treat AI as a tool that raises the engineering bar.
Basic qualifications
- Bachelor's degree or equivalent
