At a median SAR 37,000/month, contract work grosses about SAR 444,000 a year over 12 months, 16% more than the SAR 384,000 permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, end-of-service gratuity, and the gaps between contracts.

Yes, for expatriates. Saudi Arabia has no personal income tax on employment salaries for Saudi nationals or expatriates, so an Algorithmic Trading Systems Engineer earning the median SAR32K/mo takes home the full SAR 384,000 per year (SAR 32,000 per month) as an expatriate. GOSI social insurance only applies to Saudi national employees.
An Algorithmic Trading Systems Engineer earning the median salary of SAR32K/mo in Saudi Arabia takes home approximately SAR 384,000 per year (SAR 32,000 per month) as an expatriate, since gross salary equals net salary with no income tax deduction.
EOSB is a lump sum your employer owes on exit under Article 84 of Saudi Labor Law, based on basic salary and years of service: half a month's wage per year for the first 5 years, then a full month's wage per year after that, uncapped. Assuming a typical 70% basic-salary split on the SAR32K/mo median, an Algorithmic Trading Systems Engineer would build up approximately SAR 56,000 by year 5 and SAR 168,000 by year 10.
No. EOSB is an employer-funded benefit that accrues separately and is paid as a lump sum when you leave, it is not deducted from your monthly salary the way tax or social security is in other markets.
