Reward for Job - static or dynamic price?

Hi, I was looking for example at the following job:
https://keep3r.network/keep3r/job/0x5DDe926b0A31346f2485900C5e64c2577F43F774 with 9.86 KPR -> if KPR value move up or down -> is this value automatically updated or it is static? If static, it is it possible to adjust it after submission of a job?

Thanks for the feedback
