Optiver’s Automated Trading Systems teams strive to develop the world’s best trading software. We face a variety of problems with high degrees of difficulty: managing scarce bandwidth resources, building extremely low latency systems to respond to market events, automatically pricing diverse sets of financial instruments with extremely low error tolerance, and allowing intuitive control of a highly complex system. All of this must be done with the future of our company and of trading in mind. These systems must also be simple, flexible, and well-architected so they can quickly be changed to meet the dynamic needs of our traders. We already have a team of great developers, but we need more.
