Two Sigma Work Experiences

Tech company vibe in the hedge fund space

Senior Software Engineer • Current Employee

New York, New York, United States

November 10, 2023

Pros: Good work/life balance, feeling not so much different from Google and its previous positions. An almost obsessively tech-driven approach to investment. Nice location at Soho (as compared to mid-town like some banks). Generous home-from-home policy. People often say bad things about hedge funds in general, but TS has a generally pretty friendly culture.

Cons: There is no food provided (albeit it has decent snack bars). People like work-from-home a lot, to the point it is a bit hard to feel I belong here as a new joiner. Tech debt is often overlooked in a way that would not be tolerated at Google. The in-house eng tools are sometimes not state-of-the-art. Some signs of red-taping are observed, which I believe is a bad sign for non-executive level employees.

Senior Software Engineer • Current Employee

November 22, 2024

Pros: • generous WFH policy if that is your thing. • obsession with systematic approach.

Cons: A generous WFH policy means the office is quite empty, so if you want some chemistry among colleagues, it might be hard to find. A recent CEO change does not look very geek-friendly; that might impact the culture in the future.
