Pros: Teamwork. Company ethics. Work with people from diverse backgrounds from all over the world. Inter-office communications. Great perks. Accessibility of management.

Cons: Sometimes they will keep poor-performing people around a little too long before firing them. Also, it can take an excessive amount of work to get everyone required to sign off on a new idea.

Pros: As a software developer, I have found that everyone is very approachable across all levels in the company. If I ever have a question that needs answering, it's easy to sit down at someone's desk and get the answers I need. From a technical standpoint, I value Optiver's emphasis on starting with a simple solution and incrementally building up from there when needed. Another advantage is that since our customers are our internal traders, we have an immediate feedback loop where we can continually improve and tweak our applications until we have a really solid system. As far as company culture goes, I would say it is relaxed, and I enjoy the optional events and activities provided outside of work.

Cons: Trading is a fast-moving industry, with products and strategies changing. This can put pressure on our applications to change frequently, but also provides new problems to tackle and keeps things interesting.

Pros: Optiver is very intentional about fit. This means that employees find themselves in positions and working on projects where they are adding the most value. Optiver invests trust in people. This means that you are trusted to be honest and open, and you can trust that you can use your strengths. Optiver conducts itself with integrity. I can trust that we'll "do the right thing". Whilst that might mean that we don't participate in profitable activities that others might, it gives me confidence that we will continue to invest ourselves in trading activities that add value to the market, and that Optiver will continue to be sustainably and ethically profitable. Optiver provides a number of benefits to its employees: * CTA/metra pass * weekly massage * meals * snacks * facilities (games room, gym in building with trivial initiation fee) * 401k match * great health insurance * social opportunities.

Cons: Optiver is a reasonably small company with a flat structure. This is great for some, but for others who have a high need for boundaries, structure, and procedure, it might not be an ideal environment. Optiver can move slowly at times, being intentional about "new" things. They thoroughly think about whether new activities add market value, are compliant, and have well-understood risks and rewards. Some won't be accustomed to this and potentially find it frustrating.
