  • Support compatibility across avionics ecosystems and external hardware devices

  • Collaborate with QA and lab teams on real-device validation and testing

  • Contribute to long-term architecture decisions for desktop and mobile platforms

  • Use AI-assisted development tools (e.g. Claude, Codex) to support implementation, debugging, testing, and refactoring

  • Participate in code reviews, technical discussions, and mentoring activities

  • Work closely with product, DevOps, QA, and engineering teams in an international environment

Ideal candidate profile

  • Hands-on experience with modern frontend frameworks (preferably React)

  • Experience with cross-platform technologies such as Tauri, Electron, React Native, Flutter, or similar

  • Good understanding of native platforms: Windows, macOS, Android

  • Experience with backend or systems programming languages such as Rust, C++, C#, Java, Kotlin, or Swift

  • Experience working with filesystems, removable media, binary formats, or hardware/device integrations

  • Strong debugging and troubleshooting skills in complex production environments

  • Testing mindset — automated, integration, regression, and hardware-related validation

  • Ability to work independently and make architectural decisions

  • English min. B2

Nice to have:

  • Experience with Tauri + Rust stack

  • Experience in aviation, avionics, or other safety-critical industries

  • Knowledge of CI/CD pipelines for desktop/mobile applications
