Perplexity is looking for a highly skilled Senior or Expert Systems Engineer to join our Search Core team
This role is critical to building next-generation search products and technologies. You will help drive key decisions around the architecture, design, and implementation of foundational components in our technical stack
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
Preferred experience
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
