For higher education teaching positions in the UK, the role is called "teaching fellow", very often part-time and short-term.
PhD expected as there are so many candidates longing for any sort of position on the job market.
This type of position usually expects a track record of University teaching at undergraduate and postgraduate level, and probably expects too more often than not a track record of published research, following the long-standing cliche - true or false is beyond the point: good researchers make good teachers.
The worst part of the deal is probably the part-time aspect, as teaching can easily take a full-time commitment, but higher education institutions keep careful tracking of how full-time staff split their time between admin, research and teaching activities. This in turn gets used to draw in casual teaching staff.
