Machine Learning Research Scientist

Position Overview

Sentra is building organizational superintelligence through memory infrastructure that reasons across time, causality, and context. As a Research Scientist, you will tackle fundamental problems in knowledge representation, temporal reasoning, and semantic compression. You will design and implement systems that maintain execution state for entire organizations, consolidate millions of micro-events into durable knowledge, and learn patterns that predict events before it happens.

Key Responsibilities

• Build LLM-powered information extraction pipelines that process unstructured communications and text data into structured entity-relationship representations.
• Develop memory consolidation algorithms that validate information through multiple observations, merge duplicate entities, and prune ephemeral data.
• Design temporal knowledge graph architectures that model organizational execution state as living, continuously updated systems rather than static records.
• Create graph attention mechanisms and reasoning systems for complex causal queries about blockers, dependencies, and outcome patterns.
• Research lossy semantic compression using information-theoretic principles to condense event streams into query-relevant long-term memory.
• Design entity resolution systems handling identity evolution where entities merge, split, and transform through time.
• Build meta-learning systems that identify organizational patterns and recognize when current situations match historical success or failure indicators.
• Develop privacy-preserving cross-organizational learning using federated learning and differential privacy techniques.
• Publish research findings and contribute to the broader research community on knowledge graphs and organizational intelligence.
