From context it is a Product Manager.

Project Manager: manages day-to-day running for project e.g. fighting for the right number of devs, designers etc

Product Manager: (also product owner) determines what the product should look like.

> The person who determines what the end result should look like.

Not necessarily. In many companies 'project manager' is just the techie name of what used to be called a 'secretary'.

It can be Product Manager too. Product Manager has more of a focus on customer/marketing, whereas Project Manager oversees the technical teams implementing Product Manager's ideas.

A Product Manager doesn't need to have a technical background, but a Project Manager should.
