Two translation internships seen recently:
STAR in Dublin is offering internships for translation project management, beginning September for a period of 5-6 months. No details about remuneration.
Remote internship offered by Coalition for International Initiatives for a French or Spanish native speaker to translate their materials out of English. Minimum 10 hour a week commitment. Seems pro bono.
As always, disclaimer: all information provided in good faith, but I don't know these organisations personally and make no claims or guarantees.
