Your work will directly impact our customers in the form of products and services that make use of GenAI technology. You will leverage Amazon’s heterogeneous data sources and large-scale computing resources to accelerate advances in LLMs. ### A day in the life You start your morning reviewing experimental results from a model training run you kicked off the previous afternoon, analyzing metrics and refining your approach. By mid-morning, you are whiteboarding a new algorithmic design with engineering partners, working through system integration details. After lunch, you lead a science review where you present findings and gather feedback from peers. Later, you pair with a junior scientist to debug a data pipeline issue, turning it into a coaching moment. Your day wraps up drafting a section of a research paper capturing your team's latest results. ### About the team The FAI team has a 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: Sep 29, 2026 - First seen by OpenNash: Oct 11, 2026 - Last checked: Oct 18, 2026 - Listed for: 19 days - Location: US, CA, Sunnyvale[Apply on Amazon’s careers site →](https://www.amazon.jobs/en/jobs/10564138/sr-applied-scientist-frontier-ai-assets) ## More jobs at Amazon ### [Applied Scientist II, Foundation Model](https://jobs.opennash.com/companies/amazon/jobs/257e51fe80d43fba0429/) US, CA, Sunnyvale ### [Applied Scientist II, Prime Video Personalization and Discovery Science, Prime Video - Personalization and Discovery Science](https://jobs.opennash.com/companies/amazon/jobs/a89485600c7bef82a898/) US, CA, Sunnyvale ### [Applied Scientist II, Simulation](https://jobs.opennash.com/companies/amazon/jobs/92c13022b7665a464ece/) US, CA, Sunnyvale ### [Applied Scientist III, AGI Responsible AI (RAI)](https://jobs.opennash.com/companies/amazon/jobs/6bc73f7fbfc923e8ab2f/) US, CA, Sunnyvale ### [Applied Scientist, AGI](https://jobs.opennash.com/companies/amazon/jobs/16bc584fbfd7751c9d9e/) US, CA, Sunnyvale ## 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 [Jobs in Sunnyvale, CA](/locations/us/ca/sunnyvale/)[Jobs in California](/locations/us-ca/)[Research & Science jobs](/functions/research-science/) OpenNash lists jobs from employers’ own careers sites and does not handle applications.
