Applied Scientist, JP Science and Data

We are seeking an Applied Scientist to develop and innovate on advanced LLM solutions that drive value across Amazon’s largest vendors. In this role, you will work on improving our internal LLMs to automatically enrich our shopping catalogue with hundreds of millions of items. Beyond catalogue enrichment, you will work on applying LLM technologies for the development of Amazon's new generation of vendor Paid Services, delivering high-impact machine learning models to vendors for business reasoning and support automation.

You will work directly with other scientists and engineers to translate algorithms into production systems, optimizing model performance at scale, and Product Managers to align technical solutions with business objectives.

This position is ideal for candidates with deep expertise in machine learning, demonstrated experience in developing and implementing advanced ML algorithms, strong analytical and mathematical skills, and a passion for solving complex business problems through practical applications of machine learning and statistical methods.


Key job responsibilities
The Applied Scientist is accountable for:
(1) Design and develop sophisticated ML algorithms to solve complex business problems across vendors, including novel approaches for feature engineering and model architectures
(2) Drive technical excellence through rigorous experimentation, performance validation, and collaboration with other scientists to review and improve model designs
(3) Partner with MLEs to productionize solutions and with Product Managers to identify high-impact ML applications, while being the technical voice in business reviews
(4) Develop evaluation frameworks and metrics to quantify model performance, ensuring business value through statistical validation
(5) Contribute to scientific advancement through internal/external publications, active participation in ML communities, and staying current with latest developments
