You cant have a roadmap if you dont have a destination, or at least a direction for travel for the immediate next steps.
Remarkably the article doesnt event try to define data engineering, so how you can possibly have a roadmap to it.
"SQL" is too vague and jargonistic. Could be just "data analyst". The Engineering aspect is supposed to add a more fundamental data flow approach, less business context driven and more close to the metal. This is the skillset of big data framework (streaming data) nosql etc.
We could say it puts more focus on performance, but even that is imprecise because a lot of SQL expertise is also about performant designs and for many people would claim that e.g graph DB's are not essential
