We're inspired by fields like artificial intelligence and distributed computing. Since 2001, we've searched for ways that these kinds of technologies can make us better at what we do.

Mission: We discover value in the world's data.

Two Sigma – Why Work For Us?


The global markets fuel our imagination like nothing else. Unlimited information to study. Countless ways to take action. Fast feedback. Boundless opportunity. It’s got it all.

We apply the scientific method to investment management. Some people call us systematic. Here’s what that means to us: We combine massive amounts of data, world-class computing power and financial expertise to develop sophisticated trading models. And we use technology in an effort to constantly refine our investment process and our insights into how the markets will behave. Risk is a living thing in our business, and we watch over it carefully.


We’re rigorous about our work and developing our people. We’re building great technology and a great culture. And we’re finding solutions to some of the world’s hardest problems while creating a collaborative learning environment in which to tackle them. Here you’ll find exciting challenges and diverse opportunities, and the best teachers around.

At Two Sigma we know that diversity drives innovation. One key area of focus for our diversity efforts, particularly in engineering, is the proactive engagement of women. Our Women at Two Sigma (W@TS) group supports a number of important initiatives, including our early careers mentoring program, pairing recent female engineering graduates with a mentor to guide them through their first year at Two Sigma. We also actively support the women’s engineering community at large, hosting events like Women in STEM and Women Who Code in our offices.

Each year we like to challenge ourselves with a hard, but fun, engineering problem. It always involves programming artificial intelligence systems to battle in a head-to-head competition. In previous years we’ve built AIs to play computer games, card games, and shuffleboard against our employees and each other.  2016’s epic battle saw humans and AIs squaring off across an air hockey table. That’s right—we programmed AIs to play air hockey. How? You might wonder. And who won? Check out this video to find out, and witness the complete story of the 2016 TS Cup.

We use technology to help create value for real people: through our investors and in the community around us. Retirees, researchers, students and medical patients are just some of the people who can ultimately benefit from our work. 

COMMUNITY

Learning, teaching and sharing matter to us. We value open source software, so when we created Beaker, a notebook-style development environment that allows seamless translation between multiple coding languages, we released the code. We help nonprofits make smarter decisions through our Data Clinic program. We teach the Scratch programming language to local kids. And we mentor high school robot designers for a yearly robotics competition. The world needs better ideas. We’re helping people find them.

SPONSORSHIPS

Sponsorships

Two Sigma focuses on fostering meaningful and sustainable partnerships with a variety of world-class organizations, events and activities (a selection of these appears to the right). Through our support and collaboration, we nurture the spirit of curiosity and help to encourage exploration and innovation. We are proud to partner with and sponsor:

  • Student hackathons
  • Organizations supporting women in engineering and coding
  • Coding competitions
  • Open source initiatives
  • University affiliate programs
  • Research centers

INVESTORS

Our clients are real people and include some of the world’s largest public and corporate pension plans, sovereign wealth funds, insurance companies, research institutions, educational endowments, healthcare systems and foundations. We admire what they do. And we’re proud to help them do it.

TECHNOLOGY & DATA

Technology drives our business. We use machine learning, distributed computing and other technologies to find connections in the world’s data. We’ve been pushing the frontiers of Big Data since before it was a buzzword. To us, it’s just data. We work with vast sets of it, from over ten thousand diverse sources.

RESEARCH & THE SCIENTIFIC METHOD

Guided by the scientific method, we devise models that begin with inspired ideas or economic hypotheses. In a systematic, process-driven fashion, models are expanded, tested and integrated into our investment strategies.

INVESTMENT MANAGEMENT

We’re always looking to improve our investment strategies, measuring our results as we go along. So we can make more intelligent trading decisions, with one eye on generating real alpha, and the other on effectively managing risk.

    I have been working at Two Sigma full-time (Less than a year)

    Pros

    (1) As a quant researcher, super exciting work. See the impact of your own models to bring revenue to the company, see you can predict the future by using advanced quant techniques;
    (2) Great work-life balance, the company understand that great idea takes time to become effective and it understands that letting researchers have their own schedules and pace is good in the long run;
    (3) Excellent pay with no doubt.

    Cons

    In my view, the company hires way many engineers than needed sometimes. I need to maintain the bar to be high and hire just enough and really excellent engineers, and of course treat them well. Too many so-so hires hurts the company reputation and the business.

    Advice to Management

    Keep the bar high, hires as needed.

    Software Engineer(Internship) Interview

    Anonymous Employee in New York, NY
    Accepted Offer
    Positive Experience
    Difficult Interview

    Application

    I applied online. The process took 2+ months. I interviewed at Two Sigma (New York, NY) in November 2018.

    Interview

    Coding challenge followed by onsite (some people have to pass a phone screen after the challenge). Onsite was 2 technical interviews in the morning followed by 3 behavioral interviews in the afternoon . The behavioral interviews can turn into technical discussions about abstract problems. Some of the other interviewees did a bit of coding during the behavioral interviews as well.

    Interview Questions

    • Prepare to dive deep into technical decisions you've made on past projects. Also be prepared to think through abstract design problems. I ended up making a bijection to an NP-Complete problem for a prompt during my behavioral interview.   Answer Question
