Is it permissible for a subscriber to the General Organization for Social Insurance to transfer a portion of their pension after their death as an endowment (waqf) or ongoing charity (sadaqah jariyah), or to establish a collective charitable endowment for subscribers that contributes to acts of righteousness?

A retirement pension after the death of its owner is not considered an ongoing charity (Sadaqah (definition) Jariyah) in the manner described. This is because it is either a deduction from the employee's entitlements, in which case it is considered his property and is divided among his heirs as part of the inheritance. Or it is a grant from the employer to the worker's family, in which case it is disbursed to whomever the aforementioned entity designated it for. If it is a mixture of both, then what was deducted from the entitlements is part of the inheritance, and what was a donation is for whomever it was disbursed to. Therefore, its disposition depends on the rightful beneficiary according to the details. And if the employee wishes to have an ongoing charity, he should do so from his salaries before retirement or from his retirement pension before death.
