A leading global trading firm is expanding its Core Engineering and Platform Infrastructure team in London. We are seeking exceptional C++ developers with a deep understanding of systems-level programming and a passion for performance. Ideal candidates have experience in competitive programming and are ready to tackle some of the most complex engineering challenges in finance. Key Responsibilities: Design and implement high-performance C++17 infrastructure libraries and tools. Develop ultra-low latency systems for global trading operations. Engineer core platform components: memory allocators, kernel bypass, custom RPC, and distributed compute frameworks. Optimise performance at the hardware/software boundary, including GPU acceleration and CUDA-based compute. Work on Linux kernel internals, networking stacks, and system-level debugging. Technical Requirements: 3 years of experience in C++ (C++17/20) with strong knowledge of memory management, concurrency, and performance tuning. Experience with GPU programming (CUDA), SIMD, and kernel-level development. Deep understanding of data structures, lock-free algorithms, and low-latency systems. Familiarity with Linux internals, system calls, and performance profiling tools. Background in platform engineering, distributed systems, or high-performance computing. Preferred Background: Participation in competitive programming contests (IOI, ICPC, Codeforces, etc.). Experience in high-frequency trading, market data systems, or real-time infrastructure is a plus. Please apply for more info
