Research Engineer (Index Intelligence)

Join our team as a Research Engineer (Index Intelligence) where you will be responsible for making critical decisions about web indexing and page quality. You will work across teams and have a hands-on approach to machine learning, classifiers, rankers, and calibration. Your work will have a direct impact on improving search and finding high-quality knowledge.

• 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.

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