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 industry-leading multimodal language technology powering Rufus, our AI-driven search and shopping assistant, helping customers with their shopping tasks at every step of their shopping journey.
This role focuses on developing conversation-based, 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), Retrieval-Augmented Generation (RAG), Computer Vision, Responsible AI, LLM Agents, Evaluation, and Model Adaptation.
Key job responsibilities
As a 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 Amazon-scale 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 end-to-end 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 large-scale model development, model validation, and serving.
- Communicate results and insights to both technical and non-technical 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 AI-driven shopping experiences at Amazon. This team works on every aspect of the shopping experience, from understanding multimodal user queries to planning and generating answers that combine text, image, audio, and video.
Minimum Qualifications
- PhD or Masters degree
- Experience programming in Java, C++, Python, or related language
- Experience with neural deep learning methods and machine learning
- Experience with modeling tools such as R, scikit-learn, Spark MLLib, MxNet, Tensorflow, numpy, scipy, etc.
- Experience with large scale distributed systems such as Hadoop, Spark, etc.
- Experience with generative deep learning models like CNNs, GANs, VAEs, NF, and Bayesian networks
- Experience developing and implementing deep learning algorithms, particularly with respect to computer vision algorithms, e.g., image captioning, segmentation, video processing
- Experience leveraging and augmenting a large code base of computer vision or MLLM libraries to deliver new solutions.
- Experience deploying solutions to AWS or other cloud platforms.
- Excellent communication skills, solid work ethic, and a strong desire to write production-quality code.
- Have publications at top-tier peer-reviewed conferences or journals.
