There are no tenured jobs that are easy to get, for the simple reason that firing tenured faculty is intentionally difficult. Tenure-track positions at any reputable university, and even disreputable ones, are highly competitive are require a history of research, in addition to the PhD. Mostly fresh PhDs need to do at least one post-docs in order to be considered for tenure-track. In particular, the offer of a tenure-track position is contingent on the expectation of future research output, which is not consistent with the OP's goal of taking a few months off.
