Explorers and such didnt “give” jobs to native Americans.
Native Americans had their own societies and economies way before European contact.
Europeans dealt with them as one nation deals with another: trade, negotiation, treaties, wars.
Native Americans had their own “jobs” within their “countries”.
Peaceful contact came from traders bringing more advanced European goods: cloth, steel tools, guns…and European vices (liquor) to trade for indigenously produced products: animal skins mostly.
The Cherokee, for example, began a very lucrative and lasting trade in deer skins for European markets.
Other tribes had other types of this trade.
Of course trade disputes caused friction, as did the bad effects of liquor (my speculation is that Native Americans had that peculiar intolerance for alcohol which is present in the genetics of some Oriental groups today; that may account for the seemingly more severe effect of this drug on native populations) on native societies.
Finally, colonial land pressure from an expanding population was the primary detriment to peaceful relations between natives and Europeans, exacerbated by competition between European powers who recruited natives into their wars. ( I hope this helps)
