Reason #58: You Can't Hang Your Own Shingle

Reason #56 already told you the quiet part: your “skills” live inside other people’s systems. Your week becomes revision control, DV and PV queue fights, supplier cert chasing, and ERP and BOM cleanup, and the tools that make you employable are not yours. That is why the fantasy of “I’ll just go independent” falls apart on contact.

You want the American Dream version of engineering. The version where you “own something.” Not just a house, but your time, your output, your client list, your upside. You graduate, do your time, and then you hang your own shingle and stop begging a plant manager for headcount. In mechanical engineering, that dream is usually deferred, and then quietly forgotten.

If you mean independent mechanical engineering the way most people mean it, paid advice that someone relies on, you run into the stamp problem. Real clients do not want to be your liability experiment. They want a name, a license, a traceable chain of responsibility, and insurance that does not flinch when the hardware meets the world. The standard path to that legitimacy is years of progressive experience and licensure. Four years is the minimum story people tell themselves, and it is still four years spent deep inside an institution, learning the same internal gates you were trying to escape. You do not “go solo.” You apprentice in public, under someone else’s umbrella, until a board agrees you are allowed to be blamed. See Reason #13 and Reason #17.

So you pivot to the other path people whisper about. You become so good in a niche that companies pay you anyway. But look at what the modern “niches” actually are. The leverage is in code, controls, electronics, and the parts of products that can be shipped as files, not fixtures, see Reason #7 and Reason #35. Mechanical work is the physical remainder. It is slower, heavier, compliance-soaked, and harder to sell in small chunks. Even when you are excellent, the deal still needs test rigs, supplier accounts, calibration records, certifications, and someone willing to sign off. You cannot Stripe your way out of that.

Other engineering paths can cheat this a little. Software can start as a laptop and a weekend. Embedded and EE can start as a dev board and a bench supply. You can sell a prototype, a module, a consulting hour, and iterate fast without asking a factory for permission. Mechanical can start a company too, but it tends to start as a capital plan and a liability plan. It starts as “who is paying for the prototype run, the drop tests, the returns, and the lawyer.” That is why the happier cluster exists, see Reason #38.

And it is why the inheritance breaks. People who know ME best do not see “go independent” as a realistic prize at the end of the pipeline. They see more gates. More risk. More dependence on institutions. In that house, their kids notice too, see Reason #53.

You will still hear success stories. A guy who does machine design for a niche industry. A woman who consults on HVAC. A former plant engineer who now “runs a firm.” They exist. They are just rarer than the brochures imply, and they usually arrive after a long sentence served inside other people’s walls.
