• Experience working on mission-critical or safety-relevant applications (aviation, navigation, defense, medical).
• Hands-on experience with C/C++ (performance-critical components, legacy code, or system-level logic).
• Hands-on experience with Swift or/and RUST
• Experience with performance profiling and optimization tools.
• Exposure to geospatial, mapping, or navigation-based applications.
• Experience working in an Agile / Scrum environment.
• Knowledge of CI/CD pipelines for mobile applications.

Job Responsibilities

Key Responsibilities:

• Application Development: Design and implement new features for the EFB application using C# and the .NET framework.
• Optimization: Ensure the application performs reliably under the hardware constraints of mobile devices (e.g., tablets), focusing on memory management and processor efficiency.
• Aviation Integration: Develop and maintain modules for complex flight-critical tasks, including weight and balance computations, fuel planning, and electronic logbook management.
• Data Management: Design and optimize local data-stores (embedded databases) for offline access to navigation charts and manuals.
  UI/UX Design: Create user-friendly interfaces tailored for cockpit environments, ensuring ease of use during critical phases of flight.
• Testing & Compliance: Conduct rigorous unit and regression testing to ensure software reliability, adhering to industry safety standards like DO-178C where applicable.
• Legacy Maintenance: Debug, refactor, and update existing C# codebases to add new features or improve system stability.

Department/Project Description

We are seeking a Mobile Developer to design, develop, and maintain our Electronic Flight Bag (EFB) application. You will work on a mission-critical system built in C# specifically for the Windows platform. Your role is essential in transitioning flight crews to paperless cockpits by delivering high-performance, reliable software that handles navigational charts, flight planning, and real-time performance calculations.
