Quora, Inc.

Quora, Inc. operates two platforms built around the sharing and application of knowledge: Quora, a global question-and-answer network, and Poe, an AI chat platform. The company describes its mission as growing the world's collective intelligence. Quora draws more than 300m monthly unique visitors, who post questions and receive answers from people with direct experience of the subject; the service relies on real-name policies and personalised content discovery to shape the quality of the exchange. Poe offers a single place to chat with, explore and build on a range of AI language models, and counts its users in the millions.

The engineering work behind these products is concentrated in machine learning, AI applications, data infrastructure and natural language processing. Recommendation systems determine what users see on Quora; language models and the surrounding infrastructure drive Poe. The stack in use includes Python, Kafka and Spark for big-data processing, alongside transformer-based models. Company-wide, teams span data infrastructure, machine learning and AI applications.

Quora describes itself as remote-first and says its workforce operates globally. Engineers working on either product face problems of scale - ranking and retrieval across hundreds of millions of monthly visitors on one side, and serving and evaluating a broad set of AI models on the other.
