About the role

Expert Systems Engineer for the Search Core team focused on indexing and data processing streams to build next-generation search products and technologies.

Responsibilities

  • Design and build core search engine components, especially indexing pipelines, data storage formats that operate at the scale of billions of pages
  • Develop streaming and batch data processing with YT systems for search index construction in a high-load environment
  • Push the limits of hardware performance through low-level optimizations and systems-level tuning
  • Tackle challenges in multithreading, concurrency, and system-level optimization
  • Design and build core search engine components, including indexing pipelines, retrieval algorithms, and ranking systems that operate at the scale of billions of pages
  • Develop streaming and batch data processing systems for search index construction in a high-load environment
  • Push the limits of hardware performance through low-level optimizations and systems-level tuning
  • Tackle challenges in multithreading, concurrency, and system-level optimization

Qualifications

  • 3+ years of hands-on experience in systems programming (Rust, C++, C, or similar)
  • Ownership of full project lifecycle you don't just write a fast inner loop, you care about how the system is built, deployed, operated, and scaled in production
