ABOUT YOUR SKILLS

• 7+ years of professional software development experience, with at least 5 years in modern C++ (C++11 or newer), C with Classes, or C combined with a strong understanding of object-oriented programming principles.
• Experience with end-to-end ownership of features or components in complex, interconnected systems (messaging-heavy or travel/aviation environments are a plus).
• Strong working knowledge of C, including maintenance of legacy codebases.
• Working knowledge of Java, especially for systems integration.
• Experience with Kubernetes.
• Familiarity with both Linux and Windows.
• Familiarity with Git or similar version control systems.
• Familiarity with Azure DevOps (ADO) and Agile development methodologies.
• Awareness of or experience with Security by Design principles.

ABOUT THE ROLE & TEAM

As a Senior C++/C Developer you will work on a large-scale, mission-critical middleware travel application (~200,000 lines of code). This platform serves as a bridge between messaging systems that typically cannot communicate directly — including GDS systems (Amadeus, Sabre, Apollo, Galileo), messaging platforms (MATIP A/B, MQ, RabbitMQ), file transports, and custom airline/travel protocols (IATA Type B, HTH, ADH, NBytes).
The application is primarily written in C using object-oriented patterns (“C with Classes”), with some components written in Java. We are exploring a long-term modernization effort to transition the platform to modern C++.

WHAT YOU’LL DO

• Maintain and enhance a complex C-based integration platform.
• Investigate and resolve issues in systems that rely on diverse communication protocols (e.g., MQ, MATIP, FTP, etc.).
• Contribute to system design and architecture discussions, particularly around modularization, scalability, and observability.
• Collaborate with developers, product managers, and stakeholders to deliver high-reliability features and fixes.
• Help build internal knowledge by documenting system behaviors, edge cases, and refactored components.
• Potentially lead the gradual refactoring and modernization of legacy code to Modern C++.
