About The Position

As part of our AI team, you will architect and implement improvements to the backbone of our Delphi mind architecture. The architecture is powered by knowledge graphs that capture information about the person as well as their associations, reasoning patterns, and conceptual frameworks that make each mind unique. Unlike traditional RAG systems that treat knowledge as a flat collection of documents, we’re building rich, hierarchical representations that mirror how human experts think and reason.

Requirements

• Deep understanding of how LLMs work with proven ability to apply them effectively.
• Strong experience with Python beyond surface level, including asynchronous programming and performance tuning.
• Hands-on experience with retrieval-augmented generation and context engineering.
• Skilled traditional software engineer with deep familiarity in ML/AI systems.
• Ability to architect scalable backend systems while building AI-powered features.

Nice To Haves

• Previous experience with graph-based retrieval and graph systems.
• AWS and cloud infrastructure understanding.
• Hands-on experience fine-tuning models.

Responsibilities

• Design scalable knowledge graph architectures.
• Develop novel embeddings to capture nuanced relationships.
• Build efficient indexing and retrieval for real-time querying.
• Define the core components of the human mind.
• Build strong mind architectures.
• Give customers confidence their minds improve over time.
• Advance tone and style transfer to better reflect individuality.
• Build next-generation RAG systems that merge graph-based reasoning with neural retrieval.
• Include robust evaluation frameworks to optimize quality across query types.
• Scale infrastructure to support distributed, low-latency graph operations across thousands of instances.
• Implement comprehensive monitoring and debugging tools.

Benefits
