IT Search is proud to partner with a global FinTech leader expanding its UK engineering presence.
We're looking for a Senior C++ Software Engineer to join a growing team focused on building and maintaining secure, high-throughput systems enabling real-time global payments.
In this role, you’ll work on the design and development of core backend components in modern C++, collaborating with a high-calibre team to ensure performance, scalability, and reliability in a demanding production environment.
This is a product-driven role offering strong ownership and the opportunity to shape how mission-critical financial systems are developed. You’ll be working in a collaborative environment with a strong emphasis on engineering best practices and long-term maintainability.
Key Requirements:
* Strong experience in modern C++ (C++11/14/17/20) in a production environment
* Deep understanding of performance-optimized, multi-threaded systems
* Experience with design patterns, object-oriented design, and refactoring techniques
* Proficiency in version control, testing, and peer code review practices
* Comfortable working with APIs and structured data (e.g. JSON, XML)
* Strong analytical and problem-solving skills
* Exposure to embedded systems or low-level systems development
* Background in C programming, particularly for system-level code
* Experience working in Linux environments
* Knowledge of regulated or security-critical domains (e.g. finance, telecoms)
If you're an experienced C++ developer looking to work on systems that make a real global impact, apply via the link or contact Graeme King at IT Search for a confidential conversation.
