Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable connectivity. ### The Role As a Senior Applied Scientist in Project Leo, you’ll be leading us in making critical and time sensitive decisions that impact customers. You’ll use your machine learning expertise to build solutions that can scale and solve the business problem, and your engineering experience to build systems that take those solutions to production; it's an exciting opportunity to apply data science to help improve fraud detection accuracy, inference, and customer experience monitoring activity. It’s fast paced, data driven, and impactful. ### Export Control Requirement Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. ### Key job responsibilities The position requires hands-on expertise in Analytics to identify and isolate issues, Statistical Modeling and traditional Machine Learning, the ability to write queries to aid in data extraction, and the ability to productionalize models. This role is a self sufficient scientist that can source data, build and evaluate models, and ultimately take those models and rules to deployment. You should have excellent communication skills and be able to work with stakeholders at all levels. Above all you should be a passionate, hard-working and creative person who loves creating business impact, loves solving difficult problems and doesn’t mind getting involved in the details. ### A day in the life As part of the Amazon Leo Data Science Platform team, you will collaborate with a diverse group of internal stakeholders, including fraud operations, Engineering teams, and the Data Platform, to identify and address fraud vulnerabilities. You will have the opportunity to develop rules and ML models to prevent Customer Terminal (CT) usage fraud and abuse. Your role will also allow you to leverage your customer-obsession skills by thoughtfully considering the user experience and ensuring it is not adversely affected by the mechanisms you design. If you are passionate about working with large-scale data, we offer ample opportunities to do so. ### About the team The Amazon Leo Data Science Platform team builds services to ingest, transform, and aggregate data from various devices in Leo Network, and auto detect, diagnose, and resolve issues. We use ML technology to monitor customer experience and prevent fraud and abuse. ## At a glance - Posted by the employer: May 21, 2026 - First seen by OpenNash: Aug 20, 2026 - Last checked: Oct 18, 2026 - Listed for: 150 days - Location: US, WA, Redmond[Apply on Amazon’s careers site →](https://www.amazon.jobs/en/jobs/10427350/senior-applied-scientist-amazon-leo-data-science-platform) ## More jobs at Amazon ### [Business Intelligence Engineer II, Amazon Leo, Amazon LEO](https://jobs.opennash.com/companies/amazon/jobs/845b64f6f20640ec68d3/) US, WA, Redmond ### [Data Scientist, Leo Customer Terminal](https://jobs.opennash.com/companies/amazon/jobs/5a3491e25208e223aa3f/) US, WA, Redmond ### [MAC Automation & Analytics Engineer, Leo MAC](https://jobs.opennash.com/companies/amazon/jobs/8ec635979c21ad684663/) US, WA, Redmond ### [Principal Technical Program Manager, Leo data platform platform and Agentic AI](https://jobs.opennash.com/companies/amazon/jobs/36a17eb4744597f648dd/) US, WA, Redmond ### [Sr. Business Intelligence Eng, Amazon Leo Customer Terminals](https://jobs.opennash.com/companies/amazon/jobs/de674c8934b5a25cadaa/) US, WA, Redmond ## Similar jobs at other companies ### [Senior Applied Scientist](https://jobs.opennash.com/companies/oracle/jobs/f8ed9ff14b05042cc65f/) Oracle · United States ### [Applied Scientist II](https://jobs.opennash.com/companies/microsoft/jobs/1932503c468419f688ab/) Microsoft · United States, Washington, Redmond ### [Principal Applied Scientist](https://jobs.opennash.com/companies/microsoft/jobs/6887d8f40d7a9e34526e/) Microsoft · United States, Washington, Redmond ### [Principal, Data Scientist - Applied Machine Learning](https://jobs.opennash.com/companies/walmart/jobs/8af78490b17976e76747/) Walmart · United States ### [Senior AI/ML Applied Scientist](https://jobs.opennash.com/companies/unitedhealth-group/jobs/78af7d0e20840c30720f/) UnitedHealth Group · Eden Prairie, Minnesota OpenNash lists jobs from employers’ own careers sites and does not handle applications.
