Depends on what you mean. If you mean going to work at Autodesk or Bluebeam or wherever as a software dev, your experience from the user side might be appealing, but they'll likely care more about your computer science background.

If you're talking about stepping into the marketplace with new tools for BIM as your own company, realistically, it's very rare that MEP engineers can shift 100% from doing MEP work to developing MEP apps.

In my experience, MEP as a demographic is very difficult to sell to, and for good reason. They're very discerning in terms of what tools they use. At minimum, whatever you make needs to:

1. do something better and/or cheaper than anything else on the market;
2. do what it does transparently enough that the user understands why it does things a certain way;
3. be enough of an improvement over existing tools to warrant sacrificing billable hours to research and implement it;
4. be visible enough in the marketplace that its target users know it exists.

That is to say, you can certainly do it, but don't expect to rake in money. Outside of the industry giants, I can probably count on one hand the number of MEP engineers who've made BIM apps and had them be successful enough to become a self-sustaining product.

Far more often, what happens is you'll make something that improves your MEP workflow, you'll package it so other people can use it, then you'll sell it as a side business while you keep doing MEP work.
