Responsibilities

  • Own the architecture and implementation of the vector database layer, including index structures, storage layout, query execution, and serving.
  • Drive production readiness through benchmarking, capacity planning, workload onboarding, and operational tooling.
  • Optimize recall, latency, throughput, and cost through quantization, filtered search, index refresh strategies, and compute-storage scaling.
  • Extend the retrieval stack with lexical search, fused ranking, and hybrid retrieval capabilities.
  • Define evaluation methodology, recall targets, latency objectives, cost-per-query metrics, and regression detection.
  • Set technical direction, lead design reviews, make architectural decisions, mentor engineers, and participate in on-call.

Requirements

  • Direct experience building a production vector database or approximate-nearest-neighbor search system at scale.
