Senior Applied Scientist Rufus Features Science

We are looking for a passionate talented and inventive Senior Applied Scientist with a strong machine learning background and relevant industry experience to help build industryleading multimodal language technology powering Rufus our AIdriven search and shopping assistant helping customers with their shopping tasks at every step of their shopping journey.

This role focuses on developing conversationbased multimodal shopping experiences utilizing multimodal large language models (MLLMs) generative AI advanced machine learning (ML) and computer vision technologies.

Our mission in conversational shopping is to make it easy for customers to find and discover the best products to meet their needs by helping with their product research providing comparisons and recommendations answering textual and visual product questions enabling shopping directly from images or videos providing visual inspiration and more. We do this by pushing the SoTA in Natural Language Processing (NLP) Generative AI Multimodal Large Language Model (MLLM) Natural Language Understanding (NLU) Machine Learning (ML) RetrievalAugmented Generation (RAG) Computer Vision Responsible AI LLM Agents Evaluation and Model Adaptation.

Key job responsibilities
As an Senior Applied Scientist on our team you will be responsible for the research design and development of new AI technologies that will shape the future of shopping experiences. You will play a critical role in driving new ideas roadmaps aligning with stakeholders and partner teams leading the development of multimodal conversational systems building on large language models information retrieval recommender systems knowledge graphs and computer vision. You will handle Amazonscale use cases with significant impact on our customers experiences. You will collaborate with scientists engineers and product partners locally and abroad.
You will:
Take product ideas for new features and turn them into tech solution designs and roadmaps evaluating the feasibility and scalability of possible solutions.
Lead the development of scalable language model centric solutions for shopping assistant systems based on a rich set of structured and unstructured contextual signals using deep learning ML computer vision and MLLM techniques and considering memory compute latency and quality.
Drive endtoend MLLM projects that have a high degree of ambiguity scale and complexity developing the most critical or challenging parts of the systems yourself (hands on).
Perform offline and A/B test experiments optimize and deploy your models into production working closely with software engineers.
Establish automated processes for largescale model development model validation and serving.
Communicate results and insights to both technical and nontechnical audiences including through presentations and written reports and publish your work at internal and external conferences.

About the team
You will be part of the Rufus Features Science team based in London working alongside over 100 engineers designers and product managers focused on shaping the future of AIdriven shopping experiences at Amazon.
