Is it a professional/executive management/career job, or is it a "regular" type of job?
If it is the former, that is the 10th house: 10th whole sign house = mutable Virgo, and its lord, Mercury is in mutable Pisces (in detriment) = this employment might change (a no answer to the question)
If it is the latter, that is the 6th house: 6th whole sign sign = fixed Taurus, querent's significator Jupiter (lord of querent's house, ie the 1st house) is placed there in Taurus = this would indicate long term employment (a yes answer to the question)
