Position Summary

This position is open to students currently enrolled in their first year in 4-year Bachelor's programs.

Two Sigma is a financial sciences company, combining data analysis, invention, and rigorous inquiry to help solve the toughest challenges in investment management, insurance technology, securities, private equity, and venture capital.

Our team of scientists, technologists, and academics looks beyond the traditional to develop creative solutions to some of the world's most complex economic problems.

Technology drives our business - it's our main advantage - and software engineers play a pivotal role.

Software engineers at Two Sigma focus on analysis, experimentation, design, and elegant implementation. They build the scalable tools the organization needs to explore data's possibilities and act on our findings - to mine the past and attempt to predict the future.

As a Two Sigma engineer, you'll champion the rigorous, collaborative, scientific approach that allows us to meet business needs. You'll join a forward-looking, future-reaching organization to build software that will scale with the company.

We attract engineers with a true passion for data. We seek individuals who want to build for today and invent for tomorrow. We value curiosity and insight, balanced with pragmatism and practicality. We recognize both the small steps, as well as the broad vision.

We are seeking a diverse set of software engineering interns to join our team. With a group that includes a Unix Lifetime Achievement winner, Putnam medalists, ACM Programming competition finalists, and International Mathematics Olympiad medalists, you'll be in the company of ambitious high achievers with common goals and a love of learning.

Two Sigma is committed to diversity in the technology and financial services industries. Students who are members of historically underrepresented groups are strongly encouraged to apply.

The summer internship program lasts 10 weeks and takes place at our Soho-based New York City office. You will partner with an assigned mentor and work on a single project during the course of your time here, which culminates in a final presentation.
