You could certainly choose a few paths that are likely to pay higher salary that most of the scientific computing jobs you'd likely get. On the other hand, the pay for some of those scientific computing jobs is reasonable, and often the work is more interesting for someone with your background. It's worth bearing in mind that unless you are extremely unusual, you'll need a few years training in industry as well before you are really running on all cylinders.

You'll really have to think about your priorities, but it sounds like you have a bit of time to do that.

Probably the worst case is "support programmer for a research lab", some people do well there if they love the lab and the work but it tends to combine poor pay with extremely limited options for professional growth.
