C++ Engineer – Low Latency Market Data Greenfield team – Selby Jennings job at London Full Time NEW

C++ Engineer – Low Latency Market Data (Greenfield Team)

We’re partnering with a top-tier quantitative trading firm operating market-making strategies across global electronic venues. The team is building a greenfield tick-data and market-data platform optimised for deterministic latency and extreme throughput.

Role

• Design and implement ultra-low-latency market-data pipelines from exchange feed-handler to downstream consumers
• Hands-on development in modern C++23 on performance-critical hot paths
• Exchange connectivity, feed normalisation, sequencing, and recovery logic
• Deep involvement in latency profiling, optimisation, and systems architecture
• Close work with low-latency engineers and quantitative teams

Requirements

• Professional experience writing C++23 in production trading systems
• Kernel-bypass networking (e.g. DPDK, Solarflare/Onload, RDMA)
• Strong background in low-latency / high-performance systems
• Solid understanding of Linux internals, CPU architecture, cache behaviour, memory layout, and profiling tools

Nice to have

• Direct exposure to market data or HFT environments
