Job Description

• Design, develop and optimise ultra-low latency C++ trading components
• Work on critical execution paths for market data processing and order routing
• Implement lock-free and wait-free algorithms
• Optimise memory allocation, cache locality and CPU utilisation
• Reduce jitter and tail latency
• Analyse and optimise CPU behaviour (branch prediction, cache misses, NUMA effects)
• Work closely with infrastructure and network teams on kernel bypass and user-space networking
• Profile systems at instruction-level and hardware-counter granularity
• Ensure correctness, determinism and stability of production trading systems
• Participate in production releases and live deployments
• Investigate latency regressions and production anomalies
• Maintain rigorous operational discipline

Requirements

• Strong experience in C++ development for performance-critical or low-latency systems
• Proven background in HFT or ultra-low latency trading environments
• Deep understanding of CPU architecture, caches and memory models
• Strong knowledge of concurrency, memory ordering and Linux internals
• Experience working close to hardware and network layers
• Strong production mindset and sense of ownership
• Exposure to C# in trading, control or monitoring systems (highly valued)
• Experience with market data feed handlers or order gateways (highly valued)
• Prior exposure to market making or proprietary trading environments (highly valued)
• Experience with FPGA-assisted or hybrid architectures (highly valued)

Benefits

• Access to elite HFT and ultra-low latency trading environments
• Technically extreme and intellectually demanding engineering assignments
• Clear separation between execution-critical and supporting systems
• Human-sized consultancy with very high technical standards
• Long-term positioning on rare, high-value low-latency engineering skillsets
