Translator
If you are bilingual or fluent in multiple languages, add translator to the list of jobs for retirees. You’ll need to demonstrate your fluency, such as by passing a proficiency test. If you prefer to work on your own schedule, sign up with a company like VerbalizeIt, where you can opt-in to translation jobs that suit your preferences and get paid per job.
Sometimes, you’ll need other skills for particular jobs. For example, Telelanguage posted an opening for a translator to work from home with medical professionals who have limited English proficiency. The job required some medical experience.
If you really want to run with this job, it could provide great pay opportunities and other perks.
