Applied Scientist II, AFT AI, Amazon AFT AI

Are you excited about developing agentic AI LLM and computer vision models that revolutionize Amazons Fulfillment network Are you looking for opportunities to apply state-of-the-art AI on real-world problems at truly vast scale At Amazon Fulfillment Technologies and Robotics we are on a mission to build high-performance autonomous systems that perceive and act to further improve our world-class customer experience at Amazon scale. To this end we are looking for an Applied Scientist who will build and deploy models that make smarter decisions on a wide array of multi-modal signals. Together we will be pushing beyond the state of the art in optimizing one of the most complex systems in the world: Amazons Fulfillment Network.

Key job responsibilities
In this role you will build agentic AI solutions and multi-modal deep learning models that understand how products and packages flowing through Amazons fulfillment network. You will build models that solve challenging problems like understanding warehouse operations systems or visual defect detection on Amazons entire retail catalog (billions of different items thousands of new items every day). You will work with a diverse set of very large multi-modal real-world datasets including imagery natural language and structured data. You will face a high level of research ambiguity and problems that require creative ambitious and inventive solutions.

A day in the life
AFT AI delivers the AI solutions that empower Amazons fulfillment network to make smarter decisions. You will work on an interdisciplinary project involving scientists and engineers with deep expertise in developing state-of-the-art AI solutions at scale. You will work with images videos natural language and sequences of events from existing or new hardware. You will adapt state-of-the-art agentic AI deep learning language understanding and computer vision techniques to develop solutions for business problems in the Amazon Fulfillment Network.

About the team
Amazon Fulfillment Technologies (AFT) powers Amazons global fulfillment network. We invent and deliver software hardware and science solutions that orchestrate processes robots machines and people. We harmonize the physical and virtual world so Amazon customers can get what they want when they want it.

AFT AI is spread across NA (Bellevue WA) and Europe (Berlin Germany). We are hiring candidates to work out of the Berlin location.
