Our Senior Software Engineers lead large technical projects, help set the direction for our trading infrastructure, and serve as role models within the organization. Our software engineering teams leverage technology to solve a variety of difficult problems. Our trading strategies must respond to market events in microseconds or less, and we automatically price large, diverse sets of financial instruments with extremely low error tolerance. We continually refine, store, and analyze terabytes of data produced by market activity and our trading systems. Our user interfaces must present coherent, responsive real-time visualizations of market activity and system performance while providing intuitive control of a highly complex system. Our core systems must provide a stable, performant, and trusted foundation on which our systems are built.
