- 3.0Good hours and smart people but uselessSoftware Engineer • Former EmployeeLondon, EnglandMarch 30, 2026Pros: There were good working hours and smart people.Cons: Lots of bureaucracy and planning, and it had a net negative impact on the world.
- 4.0Strong technical talent, a good place to workSenior Software Engineer • Current EmployeeNew York, New York, United StatesJuly 30, 2021Pros: Work with talented people. Generally well managed. Good work-life balance. Relaxed atmosphere. Managers are technically sophisticated. Great mobility within the company.Cons: Very few checks on management authority: no 180 review, no peer feedback. Disputes with management feedback have no recourse. Advice: make sure you trust your manager. Sometimes it feels too laid back, and no one is held accountable for serious issues. Bad managers aren't found and removed. Much of the trading technology is mature. You won't get to do much new development. TSS is a mess. Avoid it. They cannot find a vision that works.
