Qualifications

  • You must have:
  • Experience designing and building search infrastructure — the data pipelines that feed it, the APIs that expose it, and the operational tooling that keeps it healthy.
  • Experience with Python and modern web frameworks (we use FastAPI with strong typing and Pydantic — but we'd rather hire the right search engineer and have them pick up the language than compromise on search depth).
  • Experience with cloud-managed search deployments (we run on Elastic Cloud / AWS).

Responsibilities

  • Our retrievals team is responsible for making millions of financial documents (bond deals, credit reports, legal filings, earnings transcripts) searchable and retrievable across the platform.
  • This means you will:
  • You'll make the architectural decisions about how documents are indexed, searched, and served, and you'll be accountable for the system's performance, reliability, and relevance at scale.
  • You'll design the interfaces, services, and guardrails that make the retrieval layer usable, reliable, and self-service where possible.
  • You'll have direct input into the technical roadmap.
  • You'll be a senior IC with real influence on engineering standards.
  • Not just usage — you've been responsible for how the system is designed, operated, and scaled.
