Updated open position template

In anticipation of the board of directors coming up with a draft salary and organizational structure, here is my suggestion for an updated position template based on the recently published open position.

@bvhme Is this ready to progress from draft to pull request?

@clausmullie not yet, there are still some things to be decided upon. This is not a meaningful addition until then.

Thanks :)
