Director, Software Engineering - Machine Learning

Boston, MA

Who We Are:

Machine learning is extensively used across Twitter to build user experiences ranging from onboarding users to serving their timeline to everything in between. Cortex is the central ML org at Twitter which is focused on advancing ML inside & outside Twitter. In the Signals group in Cortex our goal is to build a deep understanding of Twitter’s massive data and extract rich modeling signals to enable high speed and high quality of product development. 

 

Twitter has a rich variety of data sources including text, media, graph etc which interact with each other in a complex manner. These data sources capture interests & conversations from our users (in hundreds of millions) about real-world events, topics and entities (in tens of millions) on a daily basis. By building a deep understanding of this data and extracting rich signals, we can build delightful user experiences which connects the right user with the right content/user at the right time in the right context. Some examples of such signals are extracting entities, classifying into topics, deriving latent embeddings, computing similarities etc. 

 

Doing this work poses both modeling as well as engineering challenges. We deal with a massive amount of data consisting of billions of tweets and huge follow graph. The real-time nature of Twitter makes it furthermore challenging requiring offline as well as online processing. 

 

We have a mix of Applied ML engineers & ML Infra engineers who work together to explore & build new modeling signals and scale them to augment Twitter’s ML capability. Finding the right balance between innovation and impact is key to making this org successful. This is an exciting and creative area, with a unique opportunity to push the boundaries of machine learning further.
