IT Search is proud to partner with a global Fin Tech leader expanding its UK engineering presence.

We're looking for a Senior 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.

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)
