• We will prioritize candidates who are able to commit to these start dates. Please state your availability and graduation date clearly in your resume.
• Applications will be reviewed on a rolling basis. We encourage you to apply early.
• Design algorithms and systems that leverage LLMs and generative models for content-to-commerce matching, product summarization, etc
• Explore novel architectures and strategies for generative recommendation systems
• Contribute to the research community via internal papers, patents, or external publications
• Drive scientific rigor while balancing real-world constraints

Requirements

• Individuals who are completing or have recently completed a PhD degree in Computer Science, Machine Learning, Artificial Intelligence, Statistics, or a related technical field
• Experience with LLMs (e.g., GPT, LLaMA, PaLM) or diffusion/generative models, through research or practical application
• Proficient coding skills in Python and hands-on experience with deep learning frameworks such as TensorFlow or PyTorch
• Demonstrated ability to conduct rigorous research and analyze large-scale data
• Strong problem-solving skills and a high sense of ownership

Preferred Qualifications

• Publications in ML/AI conferences (e.g., NeurIPS, ICML, ACL, SIGIR, KDD, CVPR, RecSys)
• Experience with recommendation systems, retrieval models, or multi-modal learning
• Familiarity with building and deploying real-time, scalable ML systems in production
• Background in e-commerce or related applied AI research domains
