Real-Time Low-Latency C++ Engineer

Luxoft; Singapore; On-site; SGD 120,000 - 190,000; Full time

Job summary

Luxoft Singapore is seeking a highly skilled C++ engineer to design and build high performance, low latency systems that process real time data. You will optimize from algorithms to networking and OS interactions to achieve microsecond-scale throughput.

You will design, implement, and maintain C++ services handling high message rates, profile performance, and collaborate with trading and infrastructure teams to deliver robust solutions.

Qualifications

• Strong proficiency in modern C++ (C++17/20 or later).
• Hands-on experience with Market Data.
• Solid understanding of concurrency and synchronization (lock free / low lock patterns, atomics, memory models, etc.).
• Proven experience building performance critical, real time, or low latency systems (e.g., networking, trading systems, telemetry, gaming engines, or similar).
• Strong knowledge of computer science fundamentals: data structures, algorithms, memory management, and optimization.
• Practical experience with Linux systems programming (sockets, epoll/select, threads, memory management, CPU affinity, etc.).
• Experience using profiling, benchmarking, and performance analysis tools (e.g., perf, valgrind, flame graphs, CPU/memory profilers).
• Proficiency with version control (Git) and standard build systems (CMake, Ninja, etc.).
• Excellent problem-solving skills and attention to detail; ability to work in a fast-paced environment.

Responsibilities

• Design, implement, and maintain high performance C++ services handling high message rates and low latency workloads.
• Optimize existing components for latency, throughput, and CPU/memory efficiency.
• Develop and tune networking, messaging, and I/O layers to handle large data volumes reliably.
• Profile and debug performance issues at application, OS, and network levels.
• Collaborate with quantitative, trading, and infrastructure teams to translate requirements into robust technical solutions.
• Write clean, production quality code with appropriate tests and documentation.
• Participate in code reviews, design discussions, and continuous improvement of engineering practices.
