The correct spelling of "dost job" is actually "doss job," with the IPA phonetic transcription /dɒs dʒɒb/. In British English slang, "doss" refers to sleeping or lazing around, while a "doss job" is an easy or lazy job. The mishearing of "doss" as "dost" may have been influenced by the archaic second-person singular form of "do" (i.e. "dost thou"). However, the actual word is "doss," and it's important to use the correct spelling to avoid confusion or misunderstandings.
