Javascript and pdfkit for drawing children resources

We are looking for a programmer with Javascript experience to collaborate with us in the short and long term. We have many layouts drawn, that we need to be coded into javascript, as we are launching a new product.
As a first stage, we currently have some specific layouts that you will need to draw in a PDF, with the help of the library PDFkit. These layouts will represent Maths questions. These layouts have a specific font, colours, and designs as well as some variables (numbers or text) which are received as a parameter.
Given this layout (provided as a .png image or powerpoint), the programmer should be able to code a javascript function that draws the corresponding layout in the PDF.
The documentation of PDFkit library can be found at: pdfkit.org
