C++ Software Engineer – Critical Trading Systems
Location: City of London – 5 days onsite
Employment: Permanent, full-time
We are hiring multiple C++ Software Engineers to build and support business-critical systems used across a fast-paced trading environment.
You will work on high-performance applications that sit close to the trading lifecycle, including real-time market data, trade execution, pricing, risk, and position management. These are production-critical platforms where performance, reliability, and correctness matter.
This is a hands-on engineering role offering meaningful ownership. You will contribute across the full development lifecycle: designing new functionality, writing production-quality C++, improving existing systems, and supporting the applications you build.
Responsibilities
- Design, develop, and maintain performance-critical trading applications in C++
- Build systems that process real-time market and trading data
- Work closely with traders and other business users to understand requirements
- Improve system performance, reliability, scalability, and observability
- Investigate production issues and carry out root-cause analysis
- Contribute to technical design and architectural decisions
- Take ownership of systems from initial development through to production support
- Participate in an on-call rota for critical trading applications
