The AWS Marketplace team is looking for an Applied Scientist to help build and improve our AI/ML-Powered Discovery systems. The ideal candidate is passionate about applying machine learning and artificial intelligence to complex information retrieval challenges, with experience in search, recommendations, or personalization. You'll work alongside senior scientists and engineers to develop models and systems that power traditional discovery experiences — such as search ranking, query understanding, and personalized recommendations — built on rich product knowledge graphs and structured metadata. You'll also help extend these foundations into emerging agentic discovery experiences, where AI agents leverage these retrieval and knowledge systems to help customers find and evaluate software solutions. This is a great opportunity to have direct impact on the future of software discovery on AWS Marketplace.
Key job responsibilities
- Design, develop, and deploy AI/ML models for search ranking, query understanding, recommendation, and discovery systems
- Develop and improve information retrieval systems that operate over complex product taxonomies, knowledge graphs, and structured/unstructured metadata
- Build relevance models that capture nuanced relationships between customer intent, product capabilities, and domain-specific context
- Advance both traditional discovery experiences (search, browse, personalized recommendations) and agentic discovery with multi-agent systems
- Conduct experiments and A/B tests to measure and improve the relevance and performance of discovery features
- Analyze large-scale datasets to identify patterns, generate insights, and inform model development
- Collaborate with engineers and product managers to integrate AI/ML solutions into production systems
- Stay current with relevant research in information retrieval, knowledge representation, NLP, and recommendation systems, and apply findings to improve our systems
About the team The AWS Marketplace & Partner Services Science team is at the forefront of developing and deploying AI/ML systems that serve multiple critical stakeholders:
