wedgetechflash; Dubai; On-site; AED 240,000 - 420,000; Full time

Job summary

wedgetechflash is seeking an experienced C++ engineer to design, implement, and optimize high-performance software for compute-intensive workloads on CPUs and GPUs. You will work on low-level systems, memory layouts, and parallel code paths using CUDA/HIP and Linux toolchains.

You will collaborate with a team to profile, tune, and validate performance across hardware with a focus on scalable, portable code and rigorous reviews.

Qualifications

• 2+ years of professional C/C++ development experience in systems programming or performance-focused engineering.
• Experience designing and optimizing performance-critical software including memory layout and data movement.
• Experience with multithreaded programming (std::thread, OpenMP, pthreads) and synchronization.
• Hands-on modern C++ (C++11 and later) including memory management, pointers, templates and OOP.
• Experience developing and debugging on Linux using gcc/clang, gdb, and make/CMake.
• Strong grasp of data structures, algorithms, and their performance trade-offs.

Responsibilities

• Design, develop and maintain high-performance C++ software for compute-intensive workloads.
• Write and optimize parallel code for multi-core CPUs and GPUs, including CUDA/HIP kernels.
• Profile applications, identify bottlenecks in compute, memory and I/O, and deliver measurable speedups.
• Optimize memory layout, access patterns and data movement across the memory hierarchy.
• Work with Linux systems internals: processes, threads, synchronization and virtual memory.
• Write clean, well-tested, maintainable code and take part in code and design reviews.
• Benchmark, debug and validate correctness and performance across hardware platforms.
• Collaborate with the team to evaluate new hardware, toolchains and optimization techniques.
