This job advertisement refers to "Meta" several times, mentioning tasks as for example to "maintain information about requests on Meta" and "provide regular updates on Meta pages". Along with this, the job also includes "engaging relevant groups on platforms such as Facebook" and requires a "familiarity with Meta-Wiki, Telegram, Facebook, and similar platforms".
I presume that whenever "Meta" or "Meta pages" are mentioned, it refers to Wikimedia Foundation's own "Meta-Wiki" wiki, rather than Meta Platforms, i.e. the owner of Facebook? This should be clarified within the job advertisement, in order to remove any risk of ambiguity or misunderstanding.
