Well the sources are available.

The notification widget is a Qt Quick (https://doc.qt.io/qt-5/qtquick-index.html) application: There are the Qml script part and the C++ plugin part. The notification position is calculated in the C++ plugin.

The KDE is releasing the plasma notification as part of the plasma-workspace (https://cgit.kde.org/plasma-workspace.git/).
Probably this: void NotificationsHelper::repositionPopups() : https://cgit.kde.org/plasma-workspace.g ... r.cpp#n278

Just for reference for those interested, I filed a bug report for this:
Slightly increase notification pop up's distance from the screen edge
