An excellent place to work

Production Engineer • Current Employee

Chicago, Illinois, United States

Pros: Loads of very talented people to work with. Some other review said high density talent, which is a great way to describe it. Great compensation, especially considering WLB within the industry. Lots of bleeding-edge technology and interesting problems to solve. They have world-class HPC infrastructure and really cool, bespoke hardware. Great culture. Many people have been here for 10+ years, and everyone seems very happy. Very few egomaniacs, especially for a place with so many talented people.

Cons: Tech debt coupled with complex systems with lots of bespoke hardware and software. It's very difficult to really feel completely comfortable and knowledgeable, even if you are very smart and have spent a good amount of time here. Very flat and distributed organization can lead to feeling like there is a lack of direction at times. Not really specific to Jump, but similar to most HFT firms, the compensation and career path can be very unclear.
