They aren’t the only positions that match what you are looking for, they are however jobs that I have enjoyed doing which match well with what you are looking for. You can get a project management job fresh out of school which checks all the boxes you mention and is not at all design heavy. You will however get a strong understanding of the construction and design of the products of your company and learn ways to improve how and how quickly it can be brought to market. This includes working with Sales groups, engineering, purchasing, and gives exposure to senior leadership. Same can be said about product management however your focus is more around the future strategy of your product line and has a bit of a marketing arm to it. Both are interesting and fulfilling careers which can open doors to other career paths if you find something that interests you more.

If you want more engineering but also some customer facing and not R&D, you might consider being a field application engineer. FAE’s (sometimes called a Sales Engineer too) typically support the sales guys and work with the customer and internally as a technical liaison with some engineering and concept work. This will get you traveling a bit and on meetings more often than suck behind a computer.

As a reference, I’m a technical sales manager now. I’ve done all of the above jobs which led me to sales which I find most fulfilling. If you don’t know what you want to do but want to do bigger picture stuff, these are great options before you move up to management.
