Seeking an Applied Scientist to build Amazon's next-generation customer memory and personalization systems. This role involves designing and building ML and LLM-powered solutions for extracting, curating, and reasoning over customer knowledge to power personalization. The work spans problem formulation, modeling, experimentation, and production deployment at scale, focusing on areas like fact extraction, memory quality, temporal reasoning, and grounded personalization within a large-scale, low-latency environment.

What you'd actually do

  1. design and build ML and LLM-powered solutions for Amazon's customer memory and personalization systems
  2. work on how customer knowledge is extracted, validated, and applied in production systems
  3. own the end-to-end delivery of ML solutions, from problem formulation and modeling to offline and online experimentation, and production deployment at scale
  4. deliver high-quality, scalable systems that power customer-facing experiences
  5. drive work across areas such as fact extraction, memory quality and lifecycle, temporal reasoning, and grounded personalization, while navigating tradeoffs between quality, latency, and coverage

Skills

Required

  • Knowledge of programming languages such as C/C++, Python, Java or Perl
  • Experience in patents or publications at top-tier peer-reviewed conferences or journals
  • PhD, or a Master's degree and experience in CS, CE, ML or related field research
  • Strong communication and collaboration skills

Nice to have

  • Experience in building and launching deep learning and machine learning models for business applications
  • Solid knowledge of big data and cloud technologies (e.g., Spark, AWS, etc.)
  • Experience with information retrieval, recommender systems, natural language processing, and/or personalization algorithms
  • Publications at top Web, Machine Learning, Natural Language Processing conferences such as KDD, ICML, NeurIPS, ACL, EMNLP, etc.

What the JD emphasized

  • move beyond reacting to customer behavior, to actually understanding and remembering it over time
  • extracts, curates, and reasons over customer knowledge
  • transforming noisy, unstructured signals into durable, high-quality representations of customer preferences, intents, and life events
  • using them in real time to improve customer experiences
  • large-scale machine learning, generative AI, and distributed systems
  • real-world constraints of scale, latency, and quality
  • defining how Amazon understands its customers, and how that understanding is applied across the shopping experience
  • end-to-end delivery of ML solutions
  • production deployment at scale
  • high-quality, scalable systems
  • customer-facing experiences
  • fact extraction
  • memory quality and lifecycle
  • temporal reasoning
  • grounded personalization
  • navigating tradeoffs between quality, latency, and coverage

Other signals

  • customer memory
  • personalization systems
  • LLM reasoning
  • recommendation systems
  • information extraction
  • knowledge representation
