Twitter is the heartbeat of the world: it is the only platform that offers insight into everything that is happening live. Our challenge: content that's posted on our platform is very rich, and our users' interests very diverse. Machine learning can help us connect users to the right content, and improve the quality of our products.

 

As a centralized machine learning team within Twitter, Cortex builds a platform bringing deep learning to all of Twitter BlueBird and Revenue products.

What You’ll Do:

 

You will work with our team of machine learning experts and software engineers to design one of the strongest machine learning platforms in the world, based on the latest deep learning, and powered by Twitter data.

 

Part of your responsibilities will be to design abstractions and libraries, create APIs, tools, and user interfaces to enable all engineers (even those without machine learning knowledge) at Twitter to apply machine learning to their unique problems. Other responsibilities include integration with the Twitter data stack to feed our models through the platform, as well as optimizing latencies.
