High-paying jobs that do not require German or French include IT roles, engineering positions, finance and banking jobs in multinational firms, research roles in biotech and pharmaceuticals, and consulting positions. Many global companies use English as their primary business language. Positions such as software developer, data scientist, cloud engineer, investment analyst, and research scientist often hire international professionals who speak only English. While learning a local language is beneficial, it is not mandatory for many well-paying corporate and technical roles.
