• 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.
