  • equivalent experience
  • Proven years of experience developing and deploying AI/ML products or systems at multiple points in the product cycle from ideation to shipping
  • Proven years of experience with transformer-based models (e.g., GPT, Llama)
  • Coding and hands-on experience working with foundation models
  • Ability to apply research, preferring the large-scale application of new ideas over theory and prototypes
  • Demonstrated collaboration and communication skills, both within-team and cross-team, and experience working through problems in ambiguous environments adapting to new research challenges as technology develops
  • Ability to meet Microsoft, customer and/or government security screening requirements are required for this role
  • This position will be required to pass the Microsoft Cloud Background Check upon hire/transfer and every two years thereafter

Nice to have

  • Proficiency in Python for data science workflows, leveraging libraries such as NumPy, Pandas, scikit-learn, Matplotlib, and Jupyter for data analysis, experimentation, and rapid prototyping
  • Exposure to Deep Neural Network training and inference and experience in one or more deep learning frameworks (PyTorch, TensorFlow, etc.)
  • Experience with Agent based architectures, frameworks and technologies (such as MCP, A2A protocol, Langchain, Azure AI Foundry)
  • Experienced in web application development frameworks, such as React
  • Experience delivering a Cloud SaaS product on Azure, AWS or GCP
  • A record of publication in top-tier scientific venues (ongoing or in the recent past) (e.g., NeurIPS, ICML, ICLR, ACL, NAACL, EMNLP, KDD, WWW, CHI, PNAS, Nature)
