Senior Software Engineer with C# IRC285511

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.

Requirements

Must have:

• 4+ years of professional software development experience.
• Strong experience with windows development.
• Strong understanding of software design principles, data structures, and algorithms.
• Experience working with complex, large‑scale, or long‑lived codebases.
• Strong problem‑solving skills and attention to detail.
• Good communication skills and ability to work effectively in cross‑functional teams.

Nice to Have

• 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.
