Job description

We are looking for a talented Research Scientist to help solve fundamental problems in knowledge representation, temporal reasoning, and organizational intelligence. We are an enterprise AI startup building a novel memory infrastructure that reasons across time and context to help organizations operate more intelligently.

Job Duties :

  • Build LLM-powered information extraction pipelines to structure unstructured text and communications.
  • Develop memory consolidation algorithms to validate information, merge duplicate entities, and prune ephemeral data.
  • Design temporal knowledge graph architectures that model organizational execution state as a continuously updated system.
  • Create graph attention mechanisms and reasoning systems for complex causal queries (e.g., blockers, dependencies, outcome patterns).
  • Research lossy semantic compression using information-theoretic principles to condense event streams into long-term memory.
  • Design entity resolution systems that handle identity evolution (merging, splitting, transforming) over time.
  • Build meta-learning systems to identify organizational patterns and match situations to historical indicators.
  • Develop privacy-preserving cross-organizational learning using federated learning and differential privacy techniques.
  • Publish research findings and contribute to the broader AI community.

Ideal Background :

  • 5+ years of experience building novel systems in machine learning, NLP, or knowledge graphs, evidenced by publications (e.g., NeurIPS, ICML, KDD, EMNLP) or production implementations.
  • Deep knowledge of knowledge graphs, graph neural networks (GNNs), or temporal reasoning demonstrated through shipped systems.
  • Strong ML and NLP foundation, particularly in information extraction, entity resolution, or semantic representation.
  • Proficiency in Python and modern ML frameworks (PyTorch preferred) with experience deploying models at scale.
  • Experience with graph databases (e.g., Neo4j, TigerGraph, Neptune) and large-scale graph query optimization.
  • Familiarity with information theory, compression, or temporal data structures.
  • Knowledge of causal inference, probabilistic reasoning, or Bayesian methods.
  • Understanding of privacy-preserving ML (federated learning, differential privacy).
  • Experience with distributed systems, stream processing, or real-time ML serving.
  • Ability to move between theoretical investigation and shipping practical, production-ready research.
  • Why Us :

  • Competitive base salary ($150,000 – $300,000) and significant equity (0.3% - 2%).
  • Comprehensive health coverage (medical, dental, and vision).
  • Generous wellness & productivity stipend ($2,500 / month for meals, transport, gym, etc.).
  • The latest hardware (MacBook Pro) and AI development tools (ChatGPT Pro, Claude Pro, Cursor, etc.).
  • Dedicated budget for learning and growth (conferences, courses, professional development).
  • Relocation support available for on-site hires.
  • Flexible Time Off Policy.
