I've been working on CircuitPainter, a Python-based system for generating PCBs. Some examples are here: https://circuitpainter.blinkinlabs.com/examples.html .

It uses KiCad as a backend, so you are able to take advantage of the design rule checker and other niceties that come from the traditional CAD world. We've been using it successfully to automate very repetitive design jobs at our studio.
