About the role

Perplexity is hiring a Web Access Engineer for the Crawler team to build reliable fetching and rendering systems for AI-powered search. You'll work on freely available public web content, within site permissions and approved access policies, and develop the infrastructure that supplies content to downstream indexing and retrieval systems. Your focus will be diagnosing network errors, page-loading issues, and incomplete rendering. You'll trace problems from network protocols through client-side execution, distinguish technical failures from intentional access restrictions, and turn findings into production fixes that improve content quality and efficiency at scale. Responsibilities - Own fetching and rendering improvements end to end, from investigation through implementation and production rollout, partnering with crawler engineers and SREs. - Investigate fetch and rendering failures across DNS, TLS, HTTP, caching, redirects, and client-side rendering, and classify root causes. - Improve page loading, completion detection, and content capture to preserve relevant content and handle dynamic pages reliably. - Ensure the crawler respects site-imposed access restrictions…
