Who We Are:

X serves our community of users and customers by working tirelessly to preserve free expression and choice, create limitless interactivity, and create a marketplace that enables the economic success of all its participants.

We are the Community Notes team — empowering the people to keep each other better informed, with a fully open source algorithm and data. Community Notes is constantly advancing the state-of-the-art in improving the quality of information on the internet and we employ an experimental, fast-moving, iterative approach to find product solutions that work for people of all different points of view.

What You’ll Do:

• Design and build improvements to our unique machine learning algorithm that improve Community Notes’ helpfulness, accuracy, scale, speed, and manipulation resistance

• Work in public: contribute to our open source code base, supporting external researchers and people working with our public data . For (example).

• Build efficient, scalable internal production machine learning systems and infrastructure

• Contribute to the entire product via tight cross-functional collaborations with product/eng/etc

Qualifications:

• Experience developing and shipping high-impact ML solutions end-to-end: from getting your hands dirty creating training data pipelines, to developing novel model architectures, to deploying to production at scale reliably

• Demonstrated ability to work with real-world data to extract insights, inform product roadmap and develop guiding metrics in situations that lack cut-and-dry evaluation criteria

• Familiarity with one or more deep learning software frameworks, e.g. PyTorch

• Enjoy working in a 0-to-1 space with no known machine learning or product solutions, and trailblazing to build novel solutions that work

• Love doing whatever work is needed to get things done, enabling rapid iteration on the product

Join our small and fast-paced team and empower the people to keep each other better informed.
