Careers

About the Team AWS Compliance, Security and Assurance (CSA) builds the technology that proves Amazon's compliance and security to the auditors, regulators, and customers who demand it, and that screens every party we do business with, at global scale. We operate at global scale: billions of screening events a day, hundreds of third-party audit engagements a year, and trade and product compliance spanning dozens of countries. About the Role We are hiring an Applied Science Manager to lead a team of applied scientists advancing CSA's science agenda, "Provable Trust in the Agentic Era." This agenda rests on two pillars: decisioning science, which builds ML and agentic systems that make and act on compliance decisions at scale with calibrated confidence, and verification science, which produces proof of correctness for the controls and systems that compliance depends on. Key job responsibilities What you will do: -Lead, grow, and develop a team of applied scientists, setting technical direction and raising the bar on scientific rigor across the org. -Own the science roadmap for one or more areas of the CSA agenda, spanning decision science for screening, assurance, and global product and trade compliance. -Partner with engineering, product, and compliance leaders to move science from prototype into production systems that operate under real audit and regulatory scrutiny. -Translate ambiguous compliance and assurance problems into well-posed scientific problems, then into shipped capabilities with measurable outcomes. -Represent CSA science to senior AWS leadership, to auditors and regulators where appropriate, and in the broader research community. -Recruit and mentor scientists, and build the operating model that lets a distributed science team do its best work.

We are seeking a stellar Machine Learning scientist who has 1+ years of industry experience developing and shipping large scale ML products with visible customer impact. We would prefer if your previous work has been in developing scalable Agentic, RL or forecasting systems. Strong academic background in Statistics, Machine Learning & Deep Learning is required with Tier -1 publications being a plus. Key job responsibilities In this position, you will be a key contributor (with direct leadership visibility) building, productionizing (real & batch) and measuring impact of state of the art personalized Gen AI systems for Amazon global selling partners and contribute to Amazon wide research in this area in the form of publications and white papers. You will work with global leaders and teams across time zones on a regular basis. About the team Millions of Sellers list their products for sale on the Amazon Marketplace. Sellers are a critical part of Amazon’s ecosystem to deliver on our vision of offering the Earth’s largest selection and lowest prices. In this ecosystem our team plays a critical role in enabling Sellers across EU5, China, Japan, Australia, Brazil and Turkey to make their Selection available to customers globally and deliver the experience they have come to expect from Amazon. In Jeff’s own words (2019 Q1 shareholders letter): “Something strange and remarkable has happened over the last 20 years. Take a look at these numbers: 1999 - 3% …… 2018 - 58%. The % represent the share of physical gross merchandise sales sold on Amazon by independent third-party sellers – mostly small- and medium-sized businesses – as opposed to Amazon retail's own first party sales. Third-party sales have grown from 3% of the total to 58%. To put it bluntly: Third-party sellers are kicking our first party butt. Badly.…. Why were independent sellers able to grow so much faster than Amazon's own highly organized first-party sales organization? There isn't one answer, but we do know one extremely important part of the answer: We helped independent sellers compete against our first-party business by investing in and offering them the very best selling tools we could imagine and build. Our team is pushing the boundaries of these machine learning tools in areas of Agentic, recommendation and forecasting systems to help our sellers sell more and across borders.

Are you passionate about using data and machine learning to improve how Amazon reaches customers? The Customer Targeting team is looking for an Applied Scientist to build the science behind the targeting of Amazon's marketing initiatives across channels and ad formats. You will turn business questions into modeling problems and take your solutions from prototype to production, working closely with senior scientists, engineers, and business partners. We are moving targeting toward outcome-based optimization and an AI-native, agentic way of working. In this role you will work on online optimization and reinforcement learning, incrementality modeling, and the next generation of our segment-based targeting model. You will also help build agentic workflows that make targeting decisions transparent and bring science recommendations to the people using them. The right candidate has strong quantitative and statistical skills, hands-on experience with modern ML methods, and is comfortable working through ambiguity in a fast-paced environment. You pay close attention to detail, learn quickly, and work well in a highly collaborative team. Key job responsibilities - Build online optimization (e.g., TSO, bandits) and reinforcement learning methods that optimize targeting decisions for business outcomes rather than proxy metrics. - Develop incrementality and uplift models that estimate the causal impact of targeting, and use them to improve who we target and how much we spend. - Improve the existing segment-based targeting model: engineer and evaluate new features, migrate it to new model architectures, and build automated feedback loops that retrain and improve the model from observed outcomes. - Contribute to the intelligence layer of our agentic system: build components that explain targeting decisions and propose science-driven solutions to business partners. - Design and analyze experiments (A/B tests, causal inference methods) to measure the incremental impact of targeting changes. - Write production-quality model code and partner with engineers to deploy, monitor, and maintain models. - Present methods and results clearly, backed by data, with actionable recommendations for science and business stakeholders. About the team Predictive Targeting builds the systems that decide who sees Amazon's marketing content, and how often, across Amazon's stores and channels. We are engineers and scientists working on one shared problem: making sure customers see the most relevant and engaging marketing, and making each campaign better than the last.
