About the Role
We are looking for a C++ Software Engineer to work on latency-critical trading infrastructure within high frequency trading environments. This role focuses on designing, building, and operating systems with microsecond to sub-microsecond latency constraints.
Key Responsibilities
- →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
