Two Sigma – Why Work For Us?

We might be the most interesting technology company you may not have heard of.

650+ people who believe the scientific method is the best way to approach investing.

That’s us.

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. We live for
research and development.

We focus on making real money for real people by creating investment strategies that actually work. Through our investors, we support the retirements of millions of people globally, fund cutting-edge research, advance education, and champion a broad range of charitable and philanthropic initiatives.

We’re happy to be different. And disciplined. We believe those qualities are the best route to achieving great things. We’re always looking for intellectually curious people who want to learn, invent, create, and see ideas become realities.

We are Two Sigma.

IT’S ALL CONNECTED.

    Pros

    Some of the nicest, smartest people I've ever met. Always learning, always having fun, always doing great work in an environment that is energizing, collaborative and incredibly motivating. Love it! First place I've worked where I feel truly valued, treated like a grownup and supported on all levels.

    Cons

    If you need hand holding, this might not be the place for you. You have great freedom to design your work plan and flexibility to approach your work however works best for you, which I think is fantastic, but might not work for everyone if you need rigid structure and oversight.

    Advice to Management

    Keep up the great work!
