Not familiar with data science positions I am a programmer so my comment refered to that. In building houses there's architects, and there's unskilled brick layers. The skill and training is in engineers and architects while the delegatable labour is in brick layers and foremen. In my experience, building software is more like an all architect and engineer team, you can delegate to a skilled worker of your own kind or a specialized architect, but there is no grunt work to do, with very few exceptions like QA, devops/sysadmin. It is a known phenomenon that adding people to a software project does not necessarily make it go faster, and definitely doesn't scale with speed linearly like with house building. So there's very little place for juniors.
