Open source at Two Sigma
We’re committed to sustaining digital infrastructure for the public good – and that manifests in both building our own projects and building on the work of others.

Getting together
We value unique perspectives, and our developers regularly come together at company-sponsored Hack Days and Meetups.

Sharing our ideas
We are learners and teachers, our engineers present project findings and new developments at major conferences.

Supporting the community
We believe in collaboration, and our connection to the open source community is important to us. We are a Gold Sponsor of NumFOCUS and our employees sit on the boards of several major projects.
