You will be responsible for designing and building the performance-critical infrastructure that powers the firm's next-generation systematic trading platform, including:

  • Ultra-low-latency trading and execution systems
  • Market data handlers, feed processing, and normalisation pipelines
  • Exchange connectivity, order gateways, and routing infrastructure
  • High-performance distributed systems
  • Event-driven architectures operating under strict latency constraints
  • Performance-sensitive C++ components where microseconds directly impact outcomes
Requirements
  • 2-15 years of C++ engineering experience in a trading or performance-critical environment
  • Experience within HFT, electronic trading, market making, systematic trading, or other latency-sensitive domains
  • Strong understanding of Linux internals, multithreading, concurrency, memory management, and performance optimisation
  • Expertise in low-latency systems, kernel-level development, network optimisation, market data, or exchange connectivity
  • Demonstrated tenure and track record within leading technology or quantitative trading organisations
Why Join?
  • Join as a founding engineer in a newly established systematic trading technology function
  • Build a platform from scratch rather than maintaining legacy systems
  • Influence architecture, tooling, infrastructure, and engineering best practices from day one
  • Direct impact on a major strategic growth area for the business
  • Highly competitive compensation package.
