Each year we help Amazon deliver billions of packages around the world by making it possible to hire hundreds of thousands of associates in the right quantity, at the right location and at exactly the right time. You’ll work on state-of-the-art research, advanced software tools, new AI systems, and machine learning algorithms to solve complex hiring challenges. Leveraging Amazon's in-house tech stack built on AWS, you'll have the autonomy and flexibility to bring innovative solutions to life. One day, we can bring these solutions to the rest of the world. Join ITA in using technologies to transform the hiring landscape and make a meaningful difference in people's lives. Together, we can solve the world's toughest hiring problems. The team for this position focuses on AI/ML based products to provide recommendations for job seekers at Amazon and building tools to better empower our recruiters to find bar raising talent. This team's science and engineering work is a key component in scaling the recruiting process to the over 20 million applications we get each year that result in the hiring of tens of thousands of Amazonians across the globe. We do this by utilizing both well-defined, established scientific research in the matching domain along with novel techniques developed by the team. We are looking for AI/ML scientists who can delight our customers by continually learning and inventing, and who want to use their expertise to solve real business problems. Familiarity with natural language processing, two-tower embedding models, and experience with the science associated with recommendation and matching would be ideal, but there will be opportunities to learn these skills on the job as long as you have a strong scientific foundation to build from, experience in statistical analysis, and expertise in model building.
