The culture of Jane Street is supportive and welcoming. There are no titles and no separate offices for the managers so communication is very easy and relaxed. Also, company is focused on promoting good work-life balance for the employees, so the workload is always fair.
Cons
It is not clear how to get career progression in the company. There are not many practices in place to help employees grow and develop, at least in the compliance team.
Senior ppl can feel distant and not approachable; very hierarchy in some teams; career development support may very by team, had very good manager before
Your peers are great to work with. Fun, like minded group.
The perks they offer are great and on par with a google/meta.
The pay is competitive
Cons
Management is poor within IT specifically but around the company the management lacks compared to other more established placed.
Hours can be long, nights and weekends can be typical during periods of the year.
No clear path to grow your career in IT here.
Unclear how work gets distributed with some people working on fun and interesting projects and others stuck monitoring the environment and doing boring/repetitive tasks.
