Is a Quantitative Developer (C++ / Python)'s salary tax-free in Qatar?
Yes, for expatriates. Qatar has no personal income tax on employment salaries for Qatari nationals or expatriates, so a Quantitative Developer (C++ / Python) earning the median QAR34K/mo takes home the full QAR 408,000 per year (QAR 34,000 per month) as an expatriate. GRSIA social insurance only applies to Qatari national employees.
