The tldr of Delia's situation is she and ex husband Hadrian Nott used to travel the world together adventuring (her for botany, him for funsies) until he accidentally caused her sister Cynthia Emsworth to get cursed into a beetle. Delia is desperately trying to fix that by researching and getting funding to try and turn Cindy human again.

I think the position would look like part-time keeping track of Delia and Cindy, keeping things organized, maybe actual research, but more on the herding cats side of things xD
