Reason #11: Your Specialization Dictates Where You Live

As hard as establishing a specialization in mechanical engineering is, see Reason 8, another challenge that comes up is how that specialization quietly chooses your address. The first real job gives you a niche. After that, the niche gives you a handful of ZIP codes.

If you build your experience around airframe fatigue, you will look at Seattle or Wichita. If your résumé reads pipeline stress analysis, you will study Houston apartment prices and learn the Beltway by accident. If you do NVH on trucks, you will orbit Detroit and its satellites. Marine work lives on the coasts. You do not decide where to live. Your project list does.

This would be tolerable if it stopped at work. It does not. Your partner’s career, your parents’ health, your kids’ school district, your hometown friendships: they all become secondary to the employer that needs your exact sub-specialty in the one region that still funds it. You can want Denver or Raleigh or anywhere with mountains and decent coffee. The postings do not care. They ask for five years in your precise corner of the field and they expect you to show up where that corner exists.

The longer you stay in your niche, the fewer doors open outside of it. You become experienced, which means you are hired to repeat yourself. Switching cities often means switching industries, and switching industries often means starting over. Many mechanical engineers eventually solve the problem by leaving mechanical engineering, see Reason #28.

Mechanical engineering is marketed as flexibility. In practice, it behaves like a cluster map. You move to where the cluster lives, or you stop being an ME. The breadth that was supposed to free you ends up confining you to a few shrinking places on the map.

Reason #6: Your Colleagues Are Your Competitors

One of the loneliest truths about mechanical engineering is that your classmates are not your allies. They are your direct competition. You might spend four years, or longer (see Reason #2), sitting side by side in lecture halls, burning midnight oil on the same problem sets, or cramming together for dynamics. But the moment you graduate, every one of them is gunning for the exact same handful of jobs that you are.

Mechanical engineering doesn’t offer a booming new industry that can absorb fresh graduates the way computer science or biomedical engineering can. The field is stagnant, oversaturated, and geographically narrow. This means that every position at a manufacturing plant, automotive supplier, or HVAC contractor attracts dozens if not hundreds of applicants, many of them your old classmates. If you thought you were building a network, what you were really doing was collecting a list of competitors.

And because the field is already oversaturated (see Reason #1: The field is oversaturated), the competition is even nastier. You are not only competing with your classmates, you are competing with every other graduate from the last five years who never landed a real engineering job in the first place. Many of them are still floating around, desperate to claw their way into the same narrow pipelines of work.

Inside companies, the same culture repeats itself. MEs fight over scraps of promotion opportunities and cling to “ownership” of minor projects. You’ll quickly learn that mechanical engineers are replaceable. Management knows there are plenty more just like you waiting outside the door, and so do your colleagues. The result is a culture of quiet hostility. Don’t expect camaraderie, don’t expect mentorship, and don’t expect loyalty. Expect turf wars over who gets to update drawings on a bracket assembly or who gets to give the next PowerPoint presentation.

In other words, you are not joining a community. You are joining a crowded waiting room where everyone is hoping the other guy doesn’t get called in first. And when they are, you’ll be left smiling through clenched teeth, pretending you’re happy for them while quietly updating your résumé.
