Job summary

Visionary Solutions Sdn. Bhd. is seeking a skilled Low-Latency C++ Developer to own core trading systems, including market data, order entry, and research interfaces.

You will work directly with researchers and traders on a shared codebase, influencing architecture and performance decisions. The role requires 3+ years in low-latency or performance-critical systems, strong C++17/20 on Linux, and experience with kernel bypass and eBPF-based optimization.

Qualifications

• 3+ years in low-latency, high-frequency, electronic-trading or other performance-critical systems.
• Modern C++17/20 on Linux, with strong memory, concurrency and lock-free programming.
• Low-latency networking and market-data experience; kernel bypass (e.g. ef_vi) is highly relevant.
• Practical eBPF, CPU/cache, profiling and hot-path optimization.
• A background only at tier-1 quantitative or high-frequency trading houses is required.

Responsibilities

• Design, build and own low-latency trading and research systems: market data, order entry, simulation, monitoring and research interfaces
• Take critical components from architecture through testing, production rollout, observability and maintenance
• Diagnose latency, throughput, stability and correctness across networking, Linux and application layers
• Work directly with researchers and traders on a shared, firm-wide codebase, with a real voice in architecture and performance trade-offs

Job description

Low-Latency C++ Developer, Core Trading Systems

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 interfaces
• Take critical components from architecture through testing, production rollout, observability and maintenance
• Diagnose latency, throughput, stability and correctness across networking, Linux and application layers
• Work 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 only at tier-1 quantitative or high-frequency trading houses; a firm requirement
• 3+ years in low-latency, high-frequency, electronic-trading or other performance-critical systems
• Modern C++17/20 on Linux, with strong memory, concurrency and lock-free programming
• Low-latency networking and market-data experience; kernel bypass (e.g. ef_vi) is highly relevant
• Practical eBPF, CPU/cache, profiling and hot-path optimization
• Bonus 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 standards
• A flat, low-friction, teamwork-first engineering culture with short decision paths and direct founder access
• Competitive base pay with a bonus tied to engineering delivery, not any single strategy's PnL
• Based in Hong Kong or Shanghai, with relocation support
