Innovate and prototype advanced retrieval techniques, including multi-stage re-ranking, graph-tooling for LLMs, and dynamic metadata filtering.
Design and implement schemas for complex knowledge graphs, ensuring high-performance relationship mapping and ontological integrity.
Build automated data validation and drift detection systems to monitor the quality of embeddings and the health of the vector space.
Drive technical implementation of "Memory" systems for AI agents, focusing on long-term persistence, observability, and sub-second latency.
Champion data organization standards, ensuring that disparate data sources are unified into a coherent, searchable knowledge base.
Collaborate with AI Research and Product teams to evaluate emerging database technologies (e.g., HNSW optimizations, GraphRAG) and integrate them into production.
Skills and attributes
8+ years of experience in data engineering or backend systems with a focus on high-performance data retrieval and storage.
BE/B.Tech in Computer Science, Mathematics, or equivalent. MS or PhD in a related field is a plus.
Expert proficiency in Python, Java, or Go, with a strong grasp of distributed system design patterns.
Deep understanding of Vector Databases, including indexing strategies (HNSW, IVFFlat, PQ) and distance metrics (Cosine, Euclidean, Dot Product). Experience with Pinecone, Milvus, Weaviate, or Qdrant.
