How many hours can I work in Austria on a student residence permit?

Non-EEA students need an employment permit to work, but the rules are designed to allow part-time work alongside study. You may work up to 20 hours per week, including marginal (geringfugig) employment, and this work is not subject to a labour market test.

The key condition is that your work must not jeopardise the primary purpose of your stay, which is studying. So while a part-time job is permitted, the authorities expect your studies to remain your main activity. Keep your working hours within the limit and make sure your academic progress does not suffer.
