HRT is a quantitative trading firm founded in 2002, headquartered in New York, and operating across 14 offices. Its official engineering guide separates latency-focused Trading Tech from scale-focused Research and Development and describes roles spanning C++, Python, low-level systems, hardware, infrastructure, and full-stack work. Engineering processes begin with Zoom conversations or technical screens followed by role-dependent onsite coding, debugging, technical-design, and team-fit interviews.
