Low-latency systems engineering with algorithmic depth
Source confidence: Official + candidate reports · Last reviewed: 4 Jun 2026. Exact process varies by role, office, and year.
HRT is a multi-asset quantitative trading firm founded in 2002, headquartered at 3 World Trade Center in NYC with 14 offices globally. Their "Think, Trust, Tinker, Trade" culture favors mathematicians, computer scientists, and physicists who enjoy tinkering. The interview process is heavily technical: hard algorithms, systems-level reasoning, and probability. C++ dominates internally, with Python and SystemVerilog for hardware-adjacent work (they also build internal DSLs like HeraclesQL).
