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

• 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.

• 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.

• 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.
  

• 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.
