The team is made up of talented people from all over the world, and from many different backgrounds. We work together to apply research, and build products that reach every person on the planet. We look to apply best practices and build new machine learning capabilities which refine and transform Twitter’s products.

As Senior EM for Cortex Signals Foundations you will lead teams of software and ML engineers and managers to build infrastructure, tooling, algorithms and ML models. Your teams will be responsible for  delivering the data, infrastructure,  and tools, and web applications to make ML Signals (i.e. data, ML features and embeddings) easy to train, discover and use in ML models across Twitter. You will define the vision and technical strategy, identify opportunities  and drive collaborations with customers to innovate and deliver impact in these areas.

Twitter is what’s happening and what people are talking about right now. For us, life's not about a job, it's about purpose. We believe real change starts with conversation. Here, your voice matters. Come as you are and together we'll do what's right (not what's easy) to serve the public conversation.

Job Description:

Signals Foundations is a new organization within Twitter Cortex, the central machine learning organization at Twitter. Cortex’s mission is to empower internal teams to efficiently leverage machine learning by providing platform, modeling and research expertise while advancing the ML technologies within Twitter.

As Senior EM of Cortex Signals Foundations you will lead 3 or more teams of software and ML engineers. You will define and drive the technical strategy for our Human in the Loop effort that will be responsible for accelerating availability of training data for ML models across Twitter by combining ML techniques such as clustering, active learning, weak supervision, data generation, data augmentation and human curation efforts. In addition, you will also define and lead Shared Signals Infrastructure that will devise and implement algorithms and build common infrastructure components needed by many Signals teams. Examples include embeddings infrastructure and quantization libraries. You will also manage our efforts to build tools for curators and to accelerate their impact. 

You will build a compelling vision and technical strategy by partnering with product management and senior technical leaders in your organization. You will collaborate with product management to define organizational goals, drive alignment with customers around these and ensure delivery of the goals. You will hire, mentor and grow your teams.
