As a C++ Developer, you will be responsible for designing, developing, and optimising high-performance trading systems and infrastructure that power our platforms. You will play a key role in building robust, low-latency components that are critical to our clients' trading experience, working closely with quant, product, and infrastructure teams.
Responsibilities- Design, develop, and maintain high-performance C++ components for trading platforms and execution infrastructure
- Build and optimise low-latency systems for order routing, market data processing, and trade execution
- Collaborate with quantitative analysts and product teams to implement and refine trading algorithms and strategies
- Develop and maintain connectivity to exchanges, liquidity providers, and market data feeds using industry-standard protocols (FIX, WebSocket, REST)
- Write clean, well-documented, and testable code with a focus on reliability and performance in production environments
- Participate in code reviews and contribute to engineering best practices, architecture decisions, and technical documentation
- Monitor, debug, and resolve production issues, ensuring system stability and uptime across trading hours
- Stay current with developments in trading technology, market microstructure, and financial regulations relevant to the platform
Requirements- Bachelor's degree in Computer Science, Software Engineering, Mathematics, or a related technical field
- 3-5+ years of professional C++ development experience, ideally within fintech, trading systems, or financial services
- Strong command of modern C++ (C++17/20), including STL, templates, memory management, and concurrency primitives
- Demonstrable experience building low-latency or high-throughput systems with a focus on performance optimisation
- Solid understanding of trading market fundamentals including order types, market microstructure, trade lifecycle, and financial instruments (equities, FX, CFDs, derivatives)
- Familiarity with trading protocols such as FIX, and experience integrating with exchanges or liquidity providers
- Experience with multi-threading, lock-free data structures, and profiling tools (e.g. perf, Valgrind, VTune)
- Proficiency with Linux/Unix environments, build systems (CMake, Make), and version control (Git)
- Strong problem-solving skills and the ability to diagnose and resolve complex system-level issues under pressure
- Experience in algorithmic trading, market data systems, or execution management systems (EMS) is highly desirable
