Hi,
a procurment engineer basically works in the purchasee department.. the main job responsibilities for the person is looking for the possible manufactureres of the given part. Sometimes you may need to find an quivalent or an alternate part.
Also, you have to do the vendor vist and evaluation, bt it more depends on what feild you are working for. Plus you may be responsible for planning things in advance to avoid shortages etc.
yes it is a good feild to go .. if you want to continue with the same in the future.
