After lunch, you dive into writing production-quality code for a critical component of your system, then shift to drafting a scientific document that outlines your team's next research direction. Throughout, you engage with engineers and scientists across teams, sharing your expertise and learning from theirs. ### About the team The FAI team has the mission to push the envelope in GenAI with LLMs, in order to provide the best-possible experience for our customers. ## At a glance - Posted by the employer: Oct 8, 2026 - First seen by OpenNash: Oct 11, 2026 - Last checked: Oct 18, 2026 - Listed for: 10 days - Location: US, MA, Boston[Apply on Amazon’s careers site →](https://www.amazon.jobs/en/jobs/10573797/applied-scientist-iii-foundation-ai-assets-fai) ## More jobs at Amazon ### [Principal Applied Scientist, Foundation AI Assets (FAI)](https://jobs.opennash.com/companies/amazon/jobs/1246e810d0bda87d54a8/) US, MA, Boston ### [Account Manager, Global Financial Services](https://jobs.opennash.com/companies/amazon/jobs/809b0142cb0bf3738ba9/) US, MA, Boston ### [Applied Scientist, Machine Learning Accelerator - Annapurna Labs](https://jobs.opennash.com/companies/amazon/jobs/5cda1a3241a9c057bd13/) US, MA, Boston ### [Executive Assistant, AWS Transform](https://jobs.opennash.com/companies/amazon/jobs/d24e24bb8b2b9b78ceb6/) US, MA, Boston ## Similar jobs at other companies ### [Senior Applied Research Scientist, Multimodal Foundation Models – Healthcare](https://jobs.opennash.com/companies/nvidia/jobs/2c3130c56e44a394a5bb/) NVIDIA · US, CA, Santa Clara ### [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 [Jobs in Boston, MA](/locations/us/ma/boston/)[Jobs in Massachusetts](/locations/us-ma/)[Research & Science jobs](/functions/research-science/) OpenNash lists jobs from employers’ own careers sites and does not handle applications.
