Factual is currently hiring engineers and data lovers of all levels in the SF Bay Area, Los Angeles, and Shanghai.
Factual’s location platform enriches mobile location signals with definitive global data, enabling personalized and contextually relevant mobile experiences. Built from billions of inputs, the data is constantly updated by Factual’s real-time data stack. We were named one of "50 Disruptive Companies in 2013" by MIT Technology Review. We have a terrific team that is still fairly small and an incredible CEO who was previously the co-founder of Applied Semantics (which was bought by Google and became AdSense). Factual has venture funding from Andreessen-Horowitz and our partners/customers include Facebook, Yelp, Trulia, and Newsweek.
There are many challenging problems to work on at all layers of the stack: data cleaning and canonicalization, storage, deduping, serving, APIs, improving data using machine learning, etc. A great example is one of our most recent products, Geopulse Audience, which stands at the intersection of high quality places data and large scale analysis of user geo-data: http://www.factual.com/products/geopulse-audience . If you love data, Factual is the place to be. Our main criteria are that you're smart and get things done, but you'll get bonus points for experience with Clojure (http://www.factual.com/jobs/clojure), machine learning, NLP, algorithm design, or Hadoop.
