✨ AI‑Generated
A core systems engineering role focused on building ultra-low-latency trading infrastructure. The position requires advanced C++ skills, Linux expertise, and experience with performance-critical applications.
Highlights
Own critical performance-sensitive systems with significant architectural responsibility and direct collaboration with technical experts.
Description
A multi-billion-dollar China-based quant fund is scaling its global trading infrastructure and hiring a core developer to own critical low-latency systems.
This is real systems ownership, not tickets and maintenance, and notably: Mandarin is not required.
What you'll do:
Design, build and own low-latency trading and research systems: market data, order entry, simulation, monitoring and research interfacesTake critical components from architecture through testing, production rollout, observability and maintenanceDiagnose latency, throughput, stability and correctness across networking, Linux and application layersWork directly with researchers and traders on a shared, firm-wide codebase, with a real voice in architecture and performance trade-offs
What you'll bring:
A background exclusively at tier-1 quantitative or high-frequency trading houses; a firm requirement3+ years in low-latency, high-frequency, electronic-trading or other performance-critical systemsModern C++17/20 on Linux, with strong memory, concurrency and lock-free programmingLow-latency networking and market-data experience; kernel bypass (e.g.
ef_vi) is highly relevantPractical eBPF, CPU/cache, profiling and hot-path optimizationBonus points for: a dedicated core / systems developer background rather than generalist application work
The package:
Ownership of important core components as the global business expands, with input on the engineering roadmap and standardsA flat, low-friction, teamwork-first engineering culture with short decision paths and direct founder accessCompetitive base pay with a bonus tied to engineering delivery, not any single strategy's PnLThe role can be based in Hong Kong or Shanghai
