Prime Video Shopping connects streamers to products tied to their favorite movies and shows, from licensed merchandise to the fashion and home goods that appear on screen. The experience is live and scaling across titles, surfaces, and countries, and science is what makes that scale possible: deciding which products belong with a given title, which moments in an episode are worth shopping, and how to turn a viewing session into a path deeper into a fandom. We are looking for a Senior Manager of Applied Science to own this agenda, and this is a builder and manager role. You will design, build, and ship models alongside a small, senior team, and you will decide what to build in a space where the right answers are still being defined. Current workstreams include shoppability models combining computer vision with multi-agent LLM reasoning, LLM-driven product curation across the Prime Video catalog, context-aware shopping recommendations, and the evaluation harnesses that gate what reaches customers. Your models ship inside systems owned by partner engineering teams across Prime Video and Amazon Stores, so you will set technical direction well beyond your own organization. You will also own how we measure incrementality, since proving this work changes customer behavior matters as much as building it. The surface spans on-demand video and live sports, and you will help decide where science goes next. Key job responsibilities - Design, build, and ship models. This is a hands-on role, and you will personally own significant parts of the science stack. - Own the science agenda for shoppable entertainment, working with product teams on what to build in a space where the problems are not yet well defined, and sequencing that work against product commitments and launch dates. - Earn trust across partner teams. Your models deploy into pipelines owned by Prime Video, Stores, and Ads engineering teams, so much of your impact comes from technical design reviews and shaping decisions that sit outside your org. - Define the quality bar for customer-facing output and build the systems that enforce it, including LLM-based evaluation, human calibration, and brand safety screening of generated content. - Own measurement, designing the experiments and causal analyses that quantify how shopping features change customer behavior, along with the metric definitions the program reports on. - Represent the science function to executive Prime Video and Stores leadership, including annual goal setting and quarterly business reviews.

Alexa+ is the world’s best Generative AI powered personal assistant / agent for consumers, and is becoming the conversational AI interface for Amazon services with the launch of Alexa for Shopping on Amazon.com and Amazon mobile app. At Alexa Ads, we are creating industry's first and most advanced Agentic Advertising products to drive Agentic Commerce. We are seeking an Applied Scientist to join our newly expanding team in India focused on Alexa Agentic/Conversational Ads and Personalization. In this role, you will build machine learning models that seamlessly and naturally integrate relevant advertising into the Alexa experience while deeply personalizing user interactions. You will work closely with other scientists, engineers, and product managers to take models from conception to production. Key job responsibilities - Design, develop, and evaluate innovative machine learning and deep learning models for natural language processing (NLP), recommendation systems, and personalization. - Conduct hands-on data analysis and build scalable ML pipelines. - Design and run A/B experiments to measure the impact of new models on customer experience and ad performance. - Collaborate with software development engineers to deploy models into high-scale, real-time production environments. About the team We are building a new science team in Bangalore to solve some of the most impactful problems in computational advertising. This isn't about tweaking existing models as we are rethinking how ads are ranked, priced, and personalized across voice-first and screen-first surfaces. These are problems that don't have textbook solutions. Key points to note about the team: 🧪 Greenfield team - you are not joining a mature org with rigid processes. You will shape the science roadmap, pick the problems, and define the culture from day one. 📈 Direct business impact — your models directly drive revenue. No yearly cycles to see if your work matters. 🌏 Global scope, local autonomy — collaborate with scientists and engineers across Seattle, Sunnyvale, and Bangalore, but own your problem space end-to-end. 🎓 Ship AND Publish: We encourage top-tier publications (NeurIPS, ACL, EMNLP, KDD, ICML, WWW) while ensuring your research hits production.

This is a chance to work at the front of data security and governance with Amazon scale impact on customers. As a Sr. Applied Scientist III, you bring your education, experience, and expertise in formal methods, programming languages, and automated reasoning to the permissions model behind AWS's data catalog, so that customers can state precisely who may see which data and trust that the answer holds wherever that data is read. Experience with LLMs, multi-agent workflows, and structured guardrails that raise determinism in LLM output is a plus. In this role you join a strong group of applied scientists in a highly supportive environment with real cognitive safety and room to grow. Key job responsibilities You combine deep expertise in programming languages and automated reasoning to design the language and the formal semantics customers use to express permissions over catalog resources, down to the level of individual columns and rows. The model has to stay correct, compact, expressive enough for real customer intent, explainable when it denies a request, and exhaustively testable. Much of the difficulty is navigating ambiguity to balance those properties against each other. You write clear narratives and documentation that enumerate the design choices and build consensus quickly. You lead design and delivery of scientifically complex components that are rarely revisited once shipped and that deliver measurable customer benefit. The problems are concrete: proving that a change to a policy cannot expand access beyond what the author intended, deciding whether two policies written in different models grant the same thing, showing that a fast evaluation path on the request hot path agrees with the reference semantics, and keeping permissions faithful to intent as schemas and data evolve underneath them. You maintain detailed knowledge of your team's systems and proactively drive improvements in efficiency and consistency across team boundaries. You influence your team's science and business strategy, collaborating with Applied Scientists, Engineers, and Product Managers across identity, storage, analytics, and machine learning teams, and contributing to roadmaps, goals, and priorities. You harmonize discordant views and build consensus through thoughtful feedback. Beyond your team, you apply advanced techniques to bottleneck problems and are regarded as a reliable, creative problem solver. You further AWS's academic influence through publications, talks, and advancing the state of the art in data security, governance, programming languages, and automated reasoning. About the team The team owns the permissions layer of AWS's data catalog. That covers 1/ the model and formal semantics customers use to author permissions across catalogs, databases, tables, columns, and rows, 2/ the evaluation path that turns those permissions into an authorization decision on every request, under latency budgets that leave no room for a slow answer, 3/ the detection and resolution of divergence between what a customer intended and what is actually enforced as resources change over time, and 4/ converging existing permission models onto one, including the reasoning needed to show that a migration preserves a customer's access boundaries. The team works closely with identity, storage, and analytics teams across AWS.
