Work at Perplexity Research

Perplexity offers one of the most compelling environments for greenfield AI research. Our product ecosystem, ranging from realtime multimodal assistants to open web agents, spans the full breadth of how people use AI today. We seek exceptional researchers to pioneer novel methods that redefine how millions of users navigate the internet and the world.

Each day, we encounter open research problems (and occasionally entirely new domains of research), many of which exist only at Perplexity. Our combination of scale, product ambition, and infrastructure means our researchers must innovate far beyond the current research frontier. If this excites you, apply to one of our research openings.
