Pros: My perspective is as an engineer who has been at the firm for a few years (pre-COVID). There are plenty of smart people here, though there are just a lot of people here. It's more or less a typical Chicago HFT firm inside, with standard benefits and perks. Good on WFH policy.

Cons: It has definitely changed for the worse during my time here. The rate of hiring is unbelievable, and little thought seems to go into how new people will be managed and integrated. Everyone just wants more headcount. Doubling a big firm into a very big firm in 3 years without any structural changes has just created pandemonium and confusion. My manager told me the other day we are going to outsource some software development work to Romania. That is something I never thought I would hear. Everyone is busy, and many things get started. Few get finished or show good results, though. There are profits in certain areas, but overall it feels stale despite the frantic pace. And with all of the people comes the exponential growth of politics. The management says we are flat and without politics, but it is funny (and sad) how wrong that is. Nobody on my team believes that, and judging by informal conversations, it is not believed elsewhere.

Pros: Traders sometimes bring you to expensive dinners.

Cons: Poor work environment. Low pay. Long hours.

Pros: - Compensation and benefits are great. - Feels more like a tech company than finance. Always interesting things going on, trying crazy new ideas and seeing what works out. Makes diverse bets in many different directions. - The Chicago office has improved dramatically after the 6th-floor expansion and the addition of a cafe/barista. - It's casual, not too formal or stifling. #thedailydog. Friday song. Shrec (CEO) is charismatic and knows everybody by name. - Things always seem to be getting better, not worse.

Cons: Jump isn't as agile as they think they are. There is tons of tech debt. A general fear of changes taking out production trading means that getting stuff fixed or improved is often slower than it should be. Coredev is somewhat dysfunctional. It's not exactly a meritocracy. Front office trading teams take the lion's share of profits, though back office is working its butt off to make sure everything can run smoothly. There's not much of a bigger picture. There appears to be no greater purpose to the work than profiting off the markets. Jump entices hundreds of incredibly smart people, who might otherwise be solving important issues in the real world, to just polish the P&L. For scientists and engineers, it's kind of an empty goal.
