The Prime Video Discovery Engineering team is looking for a Software Development Engineer to help build the next generation of AI-powered content discovery. Our team builds the systems that decide what customers see when they open Prime Video, generating personalized, high-quality discovery recommendations and serving them to millions of customers in real time. We turn large language models, embeddings, and semantic retrieval into customer experiences that run at Prime Video scale.
In this role, you will design, build, and operate production systems that bring machine learning to life for customers, including:
• Low-latency online serving systems that retrieve and rank personalized recommendations in real time, combining behavioral and semantic embeddings, approximate nearest-neighbor retrieval, cross-encoder rerankers, and diversity-aware ranking.
• Large-scale offline data and ML pipelines that generate, classify, embed, and index content using large language models and embedding models, orchestrated across managed workflow and inference infrastructure.
• Automated quality and evaluation systems that measure relevance, personalization, diversity, and trust and safety using LLM-based judges and offline metrics, so we can ship improvements with confidence.
• The AWS infrastructure behind all of it, defined as code, along with the experimentation framework used to A/B test changes and measure real customer impact.
A successful candidate will have a strong software engineering foundation, a passion for applied machine learning, information retrieval, and large-scale distributed systems, and the drive to own components end to end from design through production operations. You will work closely with applied scientists, product managers, and other engineers to translate ambiguous problems into reliable, high-performance systems. Experience with distributed services, data pipelines, or ML model integration in a production environment is highly valued, and a genuine interest in digital entertainment is a big plus.
