How dangerous is this for my career? I don't know if I want to be an engineer long term or go into management, and at my first job I really enjoyed the Java and Python parts of the job so the reason I moved was for more exposure to that, but I'm not sure I'll be getting that much here. I'm also doing a part-time online master's, so while here I will still be studying on the side as well.
I also really like my team, the pay is decent, and the location is good. This part of it is really my one big concern that's making me really anxious.
Edit: I'm worried about how it will look if I leave in 3-5 years, pending if I'll still even be employable at that point. I did forget to mention, most of the development is test-driven, and the testing tool for the platform isn't done yet so we are creating JUnits to test all our code. In a way, I will still be using Java and learning Java 8 for JUnits and once in awhile to work on the engine itself. I can highlight those parts of it, but I'm just worried about going in a wrong direction that makes me less competitive compared to others in the job market.
