## Job description

Perplexity is looking for a highly skilled Expert Systems Engineer to join our Search Core team. For the indexing and data processing stream. This role is critical to building 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
    
-   Knowledge of Python or other scripting languages
    
-   Knowledge of Data processing systems (YT/Kafka/Hadoop)
    
-   Passion for writing clean, efficient, and scalable systems-level code
    
-   Strong knowledge of algorithms and data structures, and the ability to apply them effectively
    
-   Deep understanding of multithreading, including various approaches, challenges, and trade-offs
    
-   Experience building high-load, distributed, and hardware-adjacent services
    
-   Solid understanding of Linux internals (syscalls, networking stack, memory model, kernel tuning)
    
-   Familiarity with low-level optimization techniques (memory management, cache efficiency, SIMD, profiling)
    

**Nice to have**

-   Experience developing core components of search engines, databases, or information retrieval systems
    
-   Understanding of search fundamentals: indexing, query parsing, ranking, and relevance
    
-   Experience with trading systems or other latency-sensitive real-time systems
    
-   Familiarity with cloud services, Kubernetes, and AWS infrastructure
