Perplexity AI AI Jobs & Careers

Perplexity AI is reinventing how people access information online with its AI-powered answer engine that combines the depth of a search engine with the conversational fluency of a chatbot. Unlike traditional search that returns a list of links, Perplexity synthesizes information from across the web, delivers clear and concise answers, and shows the sources it used -- making knowledge discovery faster and more transparent for millions of users worldwide. The company's technology stack includes Sonar, a proprietary AI model built on Meta's Llama architecture and optimized for real-time, web-grounded responses. Perplexity offers Pro Search for deep multi-step research, Spaces for collaborative work, and the Comet browser launched in October 2025. The platform also provides an enterprise tier and API access, and has expanded into partnerships with Samsung for AI-powered TV applications. With over 22 million active users and $100 million in ARR, Perplexity has attracted backing from Jeff Bezos, NVIDIA, SoftBank, and Databricks, reaching a $20 billion valuation after raising over $1.2 billion in total funding. Founded with the mission to serve the world's curiosity, Perplexity offers a fast-paced environment where engineers work at the intersection of large language models, information retrieval, and product design to challenge the dominance of legacy search engines.
