High-Frequency Quant Developer - Low-Latency Core Systems: $700K-$1 Million Basic Salary, Plus Huge Bonus Package, Sign On Bonus

High-Frequency Quant Developer - Low-Latency Core Systems Responsibilities and technical scope: - Design, build and own low-latency trading and research systems, including market data, order entry, simulation, monitoring and research interfaces. - Own critical components from architecture through testing, production rollout, observability and maintenance. - Diagnose latency, throughput, stability and correctness across networking, Linux and application layers, and work directly with researchers and traders on solutions. - Modern C++17/20 on Linux; strong memory, concurrency and lock-free programming. - Low-latency networking and market-data systems; kernel bypass, including ef_vi, is highly relevant. - Practical eBPF, CPU/cache, profiling and hot-path optimization experience. Nanosecond-level tuning may matter in selected critical paths; the role is not defined by a marketing latency number. What Our Client looks for: - 3+ years in low-latency, high-frequency, electronic-trading or other performance-critical systems. - HRT or Jump Core Developer experience is especially relevant; comparable HFT/prop backgrounds are welcome. - Strong C++ and practical Linux, networking and concurrency knowledge. Scope and decision rights - Own designated core-system components from technical design through live operation. - Have a direct voice in architecture, performance priorities and engineering trade-offs. - Help shape engineering standards and the system roadmap as the global business expands. Why this role - Real systems ownership: responsibility for important components, not isolated tickets or maintenance work. - Flat, low-friction engineering culture: short decision paths and direct contact with technical and investment stakeholders. - Predictable reward and location choice: competitive base compensation with a bonus tied to engineering delivery rather than any single strategy's PnL; based in Shanghai or Hong Kong, with relocation support. Our client wants genuine Core Developers, especially from HRT or Jump, rather than generalist application developers or pure quant researchers.
