Job Details

Requirements

  • You read and reason about LLM behavior directly.
  • You treat memory as a systems design problem.
  • You understand tool and skill systems as retrieval problems.
  • You have a working theory of context engineering.
  • You build evals before features.
  • You know vector search internals at a decent level.
  • You write precisely.

Responsibilities

  • Define what good agentic retrieval looks like.
  • Characterize the retrieval patterns inside real agent loops, name the failure modes, and turn that vocabulary into something the team and the field can build against.
  • Treat agent memory as a systems problem.
  • Investigate skill and tool retrieval as a first-class problem.
  • Design and run experiments on retrieval inside agent loops: query rewriting and decomposition, multi-hop retrieval, tool-conditioned filtering, retrieval-as-a-tool patterns, and the interplay between planner, retriever, and reranker.
  • Build evaluation infrastructure for agentic retrieval.
  • Profile agent retrieval traces end to end.
  • Study how real agent stacks use Qdrant in production.
  • Pair with design-partner teams running serious agent workloads in production, and bring their real constraints back into research priorities.
  • Influence the roadmap.
