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)
