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
