Pros
Jump is a world class trading organization. They hire the best of the best and invest heavily in all aspects of their technology stack. If you believe in yourself - your intelligence, skills, and work ethic - then this is where you want to be. Joining Jump was the best decision I ever made. I will be forever grateful that I got to be a part of this organization.
Cons
Jump is composed of many trading teams which operate largely independently of each other. This is undoubtedly an organizational strength, as it leads to small, highly motivated teams, and to an incredible diversity of ideas and strategies across the firm. But there are some downsides to this structure. There can be some reinventing of the wheel across teams. And it can be hard to find meaningful opportunities to interact with and learn from people across team boundaries.
