About Exa

You think in end-to-end impact. A signal only counts if a decision changes and search gets better

Responsibilities

  • Research and develop signals and algorithms to determine which web pages are worth indexing and which links are worth following.
  • Lead efforts to improve parsing on web pages and demonstrate the effectiveness of these improvements through data-driven results.
  • Collaborate with cross-functional teams to ensure that the solutions developed are integrated effectively into the crawling, indexing, and retrieval processes.

Requirements

  • You like working across teams. Crawling, indexing and retrieval all consume what you build
  • Hands-on ML experience with classifiers, rankers and calibration, plus strong data instincts at web scale
  • You are comfortable owning a problem with no ground truth, where the first job is defining what the right answer means
  • You care about the problem of finding high quality knowledge and recognize how important this is for the world
