A job as… a researcher, a teacher, an editor…
Your most likely prospect after completing your Research Master’s is to set up your own research programme as a PhD student. This involves carrying out research under the guidance of a supervisor, and writing a PhD thesis on the subject.
You can also embark on a career at a research institute outside of the academic setting. There are many research institutes eager to welcome researchers schooled in qualitative and quantitative research.
But you can also embark on a career outside the field of research, for instance as an editor, a language policy worker in education for a local or national government, or a teacher.
