Description
Interested in building Amazon Alexa, Machine Learning and Generative Artificial Intelligence We're building products and services that power state of the art for Amazon customers. Come join us!
The Alexa AI org is looking for a Principal Engineer to help define and build the next generation of AI-powered experiences for hundreds of millions of customers worldwide. This role sits at the intersection of advance AI research and large-scale production systems, where you will architect and deliver Pragmatic AI capabilities AI that is not just technically impressive, but reliably useful, trustworthy, and accessible to real customers in their everyday lives.
What Makes This Role Unique
You will be building AI experiences that work across the full spectrum of human interaction multi-modal (speech, text, image, video), multi-lingual (global locales with distinct linguistic and cultural requirements), and multi-model (orchestrating and routing across frontier and specialized AI models to optimize for accuracy, latency, and cost). Your systems will serve customers across a diverse range of endpoints and form factors, from voice-first devices to screen-based and mobile experiences.
Infrastructure & Systems Complexity
- Design and own the end-to-end architecture for AI capability routing and orchestration at massive scale, including intelligent query classification, model selection, and fallback strategies across heterogeneous AI backends
- Drive latency optimization across globally distributed inference pipelines, including model serving infrastructure, caching strategies, and real-time performance monitoring to meet strict customer-facing SLAs
- Build evaluation and quality assurance infrastructure including offline test sets, live traffic sampling, and automated regression frameworks to maintain high accuracy and reliability as models and locales evolve
- Architect systems that support rapid iteration and safe deployment of new AI capabilities across global regions, with robust rollback, experimentation, and observability tooling
Technology Vision
- Define the long-term technical strategy for how Alexa+ delivers high-quality, low-latency AI experiences to a global customer base, including the evolution of model integration patterns as the AI landscape rapidly changes
- Establish engineering standards and best practices for responsible AI deployment ensuring accuracy, safety, and fairness are first-class properties of every capability shipped
- Influence the broader AI platform roadmap by identifying capability gaps, proposing architectural investments, and partnering with applied science, product, and platform teams to close them
What We're Looking For
- Deep expertise in distributed systems, ML inference infrastructure, or large-scale AI platform engineering
- Demonstrated ability to define technical direction in ambiguous, high-stakes problem spaces with significant customer and business impact
- Experience driving cross-functional alignment across science, engineering, and product organizations
- A track record of delivering production AI systems that serve diverse, global customer populations
- Passion for building AI that is genuinely useful and trustworthy for real people
