This.
That was an unusual request as a first post but this forum can be brutal to newcomers.
Ahhh this forum is nothing.
Try an engineering/electronics forum. No offense to Jim because he knows his ****, but imagine an entire forum full of Jims. I'm not kidding.
Show up asking questions like seen in the Stratux thread and you'd have your butt handed to you. Hard.
This thread did get a bit too personal for a thread on a job search, but really this isn't a job board and there's no nice recruiters here to soothe the job hunting fears while buttering you up to rip you off for 10% or more of your first year salary you could have negotiated yourself.
I recommend LinkedIn if you want to be overrun with hungry recruiters with no appreciable talents other than looking nice and pushing entry level jobs. Also good for a way to network to find a few good recruiters who'll look nice while they buy you a nice lunch every quarter or so if you have real skills they want.
It's a rough go for young entrepreneurs. My sister had a Masters in Architecture with a specialty in restoration of historical buildings and worked essentially for free for years. Made a couple of developers a lot of money with a neighborhood renovation in Brooklyn.
She then went into government work, being the bureaucrat you had to get your designs past if you wanted to touch a historical building in Houston. After a couple of years and two promotions, her boss told her flatly that the lifers above her weren't nearly as good at it as she was, but they are in "jobs for life" with the impossibility of firing anyone from a bureaucracy, and that she could hang out and do what she was doing for ten more years until one of them literally died, and have their job, or that it might be smarter to leave now and move back into a private firm where she would be the interface between the developer and the very desk she was sitting in, and have a huge leg up on the process from the inside.
She hunted only a couple of months and had that private firm job and is pretty much set for a job forever and great bennies and perks.
I guess the moral of that story is just to go do something? Anything. Even if he is living in Taxi Man's basement. Gotta build some useful skill to someone into a career, and if it takes volunteering time at first to be able to put "took small firm from 5 person start up to $100M in revenue in three years, and profitability in five, including a 10% ROI for the original investors and two rounds of funding", on the resume, so be it.
Not going to get that opportunity at an established business with only a degree. They're past the point of hiring newbies. You need a place that's too small to be able to afford his skillset and he has to manage that into a long term win for himself. Whether he convinces him to finally pay him (rare: They're used to him being cheap/free), or he walks with the resume padded properly to go after the next opportunity.
Every successful entrepreneur I've met has two qualities: massively self-motivated and almost a devil-may-care attitude toward failure and success. They've been broke before and they'll be broke again, and they don't care... their world view is that everything is an opportunity, until it isn't.
They'll work an idea into the ground because they believe in it, and see if it pans out when others would have walked away long ago. When it pays off for them, it pays big.
When they fail, they shrug it off and put all their time into the next best idea on their list of five things they're trying at the same time but weren't giving the attention they needed so they could chase the first one.
If that's not your son's personality type, he's going to have to settle for managing and driving projects for an entrepreneur for very little money until he has a resume of qualifications that has the entrepreneurs referring people to him. They always share another trait: They don't have time to do everything, but they'll be up before the crack-ass of dawn and working long into the night and anyone who can give them back their TIME is worth their weight in gold to them, as long as the person they hire does things "their way" or shows them carefully a better way that'll make them more profitable.
