I would recommend joining an enterprise startup that is solving a problem for an industry you find interesting. Make sure the startup's customers are leaders in their particular industry. When working for such a startup; the primary focus will be solving your customer's problems. You should work one on one with your first couple of customers. Doing so will be very challenging and if things go well very rewarding both intellectually and fiscally. Issues of programming languages, editors, infrastructure frameworks will be secondary. But as the company grows, the technical challenges of scaling, reliability, managing teams, feature growth, etc. with will need to be met.
