The Opportunity
Ocho is partnering with a specialist capital markets technology company to recruit an experienced Contract C++ Developer to work on high-performance trading infrastructure used by financial institutions across the globe.
This is a fully remote opportunity to work on business-critical systems covering market data, trading connectivity, order entry and real-time data processing.
You'll be joining a highly experienced, distributed engineering team, working on technically challenging projects where performance, reliability and scalability are essential.
What You'll Be Doing
- Designing, developing and optimising high-performance C++ applications
- Building and maintaining real-time market data systems and feed handlers
- Developing trading infrastructure, connectivity and messaging components
- Working extensively with multithreading, concurrency and network programming
- Identifying performance bottlenecks and improving system throughput and latency
- Developing reliable, scalable applications within Linux environments
- Contributing to system architecture, technical design and code reviews
- Troubleshooting complex production issues and improving overall system performance
What We're Looking For
- Strong commercial experience developing software in modern C++ (C++11/14/17 or later)
- Solid Linux development experience
- Strong understanding of multithreading, concurrency and memory management
- Experience developing high-performance, low-latency or real-time systems
- Good knowledge of TCP/IP, UDP and socket programming
- Experience with performance profiling, debugging and optimisation
- Strong problem-solving skills and the ability to work independently
Nice to Have
- Experience within capital markets, electronic trading or financial technology
- FIX protocol, market data feeds or exchange connectivity experience
- Knowledge of lock-free programming, shared memory or inter-process communication
- Python scripting or automation experience
- Experience with distributed systems and high-throughput messaging platforms
Capital markets experience is not essential. We're equally interested in strong C++ engineers from telecommunications, embedded systems, gaming, aerospace, defence or other performance-critical environments.
Why Consider This Contract?
- Up to £450 per day – Outside IR35
- 100% remote working anywhere in the UK
- Initial 12-month engagement with potential for long-term extensions
- Work on sophisticated trading technology and high-performance infrastructure
- Collaborate with experienced engineers across the UK, Ireland and US
- Small, technically focused engineering teams with genuine ownership of delivery
