佳期投资 (JQ Investments) Tech Stack

Quantitative hedge fund building ultra-low-latency trading systems

Financial Services Shanghai 201–500 employees Founded 2012 Privately Held

JQ Investments operates a quantitative trading platform built on C/C++, Python, Go, and kernel-level networking (RDMA, DPDK, NVMe) — a stack optimized for microsecond-scale latency rather than general-purpose cloud infrastructure. The active project list reveals deep infrastructure work: compiler optimization, custom storage for petabyte datasets, and high-frequency trading system design. Pain points cluster heavily around latency reduction and training throughput, suggesting the firm is scaling both live trading and research workloads simultaneously, with engineering hiring weighted toward performance-critical roles.
