£27,854 to £36,298 pa is the salary range for the post. So if they pick someone who is less qualified or has less experience, the starting pay is £27,854. For example, applicants who have impressive record of publications and research tenure, they could be in a position to be awarded the full amount per year. Increases are possible, but depends on the job as well. For example, if the applicant did extra training and got say, a professional qualification along the time of employment, there could be a salary increment. But again, it is likely that the value would not go beyond £36, 298.
hope this helps
