Ask HN: Who is hiring? (February 2013)

Two Sigma (SoHo, NYC) - Full Time, Intern, H1B

Did you know there's a company based in New York City that has enough technology to be considered among the world's Top 250 supercomputing sites? One that imports over 5TB of data every single day, and has alumni from Google, Intel, and Microsoft?

You might think I'm talking about some stealth-mode startup, but I'm talking about where I work: Two Sigma Investments. At our core, we're a technology company applying our talents to the domain of finance. We've created a system that combines artificial intelligence and keen human insight — a system that's constantly improving and advancing.

We're looking for a diverse set of technologists to join our team. Our challenges require mastery of areas such as kernel level development, machine learning, and distributed systems. Our team includes a Unix Lifetime Achievement winner, Putnam medalists, ACM Programming competition finalists, and International Mathematics Olympiad medalists. We are proud of our individual pedigrees, but even prouder of our teamwork.

We tend to hire people with at least a bachelor’s degree in a technical or quantitative field and experience with C or languages that target the JVM, but we are open-minded in our search for critical thinkers who are passionate about technology. We analyze the data-rich domain of finance, but financial experience is not a requirement. We hope to hear from you!
