Two Sigma – Why Work With 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.

    Software Engineer Interview

    Negative Experience
    Average Interview

    Application

    I applied online. The process took 3 weeks. I interviewed at Two Sigma (London, England) in March 2019.

    Interview

    Online Hackerrank was very easy, was given 3 hours to solve two classic CS problems. Was able to solve both, check them, and even add comments to the code, with 2.5 hours still to spare.

    Phone interview was bad. Interviewer was Chinese and could barely speak coherent English. Audio quality was also terrible as it was an international phone call. Asked a few OS questions, then a main coding question. I started solving the coding question optimally but interviewer was telling me my solution was 'wrong', when what he really meant was he wanted a simpler-and-less-efficient solution. Led to a lot of confusion.

    Somehow I passed and went to onsite. Questions seemed reasonable, but not enough time was given to solve them even though I knew the solutions. And I was given a macbook with really awkwardly spaced-out keys, unfamiliar key shortcuts, and no mouse, so I was constantly making typos or struggling to use the mac-style touchpad.

    Not happy with the overall process, seemed a lot more luck-based than skill-based.
