Dialog Systems and Natural Language Understanding Researcher

software research and engineering | Palo Alto, CA | Full Time

Job Description

Ph.D in Natural Language Understanding or related field with experience in analyzing conversations

About the Job

We seek a talented researcher in dialog systems and natural language understanding to work on a variety of problems such as effective communication and engagement between humans and conversational agents, modeling conversation structure, algorithms for robust processing of spoken language. The successful candidate will be an essential part of the CHAT (Conversational Human Agent Technology) group, a new, exciting effort in the Intelligent Systems Lab at PARC that focuses on everything around conversation: how does one model the interactional layer of a conversation, how can an artificial agents communicate effectively and engagingly with a human, what can one infer from the conversation between humans. Such problems require knowledge and understanding of social sciences as well as broad knowledge of Natural Language Understanding and Artificial Intelligence techniques. Our team is multidisciplinary and allows for collaboration among researchers in a variety of fields as well as leading faculty in universities.

Responsibilities include

  • Expressing real-world problems in a mathematical and/or algorithmic form.
  • Building prototypes that can be used and evaluated by non-expert users.
  • Publishing scientific results in leading conferences in the field.
  • Patenting novel technology.
  • Communicating with business units to understand problems and explain solutions.


  • Ph.D in Natural Language Understanding or related field
  • Strong statistical and machine learning background for language understanding
  • Optimization techniques: greedy search, dynamic programming, convex programming
  • Ability to model: understand problems and be able to express them mathematically in a way that can be robustly optimized and be suitable for practical systems
  • Strong programming skills
  • Strong communication and writing skills
  • Creativity in problem solving
  • Drive to make an impact on the real world


(candidates should have some or all of the following):

  • Experience with Natural Language Understanding problems, preferrably semantics
  • Experience with dialog systems and conversational user interfaces
  • Experience with well-known Machine Learning techniques, such as Latent Dirichlet Allocation, and Markov Networks
  • Experience in formulating objective criteria that capture the constraints of the problem and optimizing them
  • Experience in implementing language understanding algorithms as opposed to invoking off-the-shelf methods is preferred.
  • Experience in programming Java, Python, C/C++
