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.
