Experience
5+ years building novel systems in machine learning, NLP, knowledge graphs, or related areas.

About the job

Researches and builds machine-learning systems that turn organizational communications and events into evolving, searchable knowledge and predictions.

What you'll do

  • Build LLM-powered extraction, memory consolidation, temporal knowledge graph, and causal reasoning systems.
  • Research semantic compression, entity resolution, organizational pattern learning, and privacy-preserving cross-organizational learning.
  • Publish research findings and contribute to the knowledge graph and organizational intelligence research community.

What they ask for

  • 5+ years building novel systems in machine learning, NLP, knowledge graphs, or related areas, evidenced by publications, production implementations, or significant open-source contributions.
  • Deep knowledge of knowledge graphs, graph neural networks, or temporal reasoning, demonstrated through shipped systems and architectural exploration.
  • Strong ML and NLP foundation, particularly in information extraction, entity resolution, or semantic representation.
  • Proficiency in Python and modern ML frameworks, with experience deploying models at scale.

Nice to have

  • Graph databases (Neo4j, TigerGraph, Neptune) and query optimization for large-scale graphs.
  • Information theory, compression, temporal data structures, causal inference, probabilistic reasoning, or Bayesian methods.
