Pros: The most productive company I've worked for in my career; everybody delivers results. Generous compensation and benefits support top talent. Technology is core to the business, not just a support function. You learn something new every day and continue to push yourself.

Cons: This is not a 9 to 5. Don't come here to coast. Expectations are high, but so are the rewards. Priorities often shift. Teams get restructured. If you want to work on a project for 2+ years, this is not the right place.

Pros: Using advanced technology Good pay and benefits

Cons: The management is involved in local corporate politics and interested in it more than the end result. But not everybody likes that; only some individuals do.

Pros: Over my time at Citadel, I have taken an internal application from the first line of code into a critical platform for how we manage and access data across the organization. Through this project, I was not only an architect and engineer, but also a product manager, user support, and salesman. I have learned that this is typical of the most successful engineers at Citadel. In order to succeed, you need to not only design systems but also intimately understand the problems we are solving and how they relate to making money and managing risk. If you cannot incorporate the last two components into the systems you design, you will not be successful. However, if you can, there is no ceiling. I now work in data engineering for the fundamental equities businesses, working on problems that enable our investment teams to gain insights from a variety of data sources. We get access to data sets that no one else gets to work with, using cutting-edge techniques with a lot of compute resources. It forces me to work creatively to come up with solutions that I cannot find in a textbook or just search for on Stack Overflow.

Cons: It is a high-pressure environment with a lot of money at stake, and that is something that you can feel as an engineer. During earnings season or at the end of a quarter, you are keenly aware that there is little room for error or missed deadlines. It does not have an academic, relaxed environment that you might find at other quant funds or tech shops. However, if you can keep focused in that kind of environment and work with a passion, there is no ceiling to your career at Citadel.
