This posting reminds me of one I’ve seen before and linked to CPNI, although CPNI’s current job listings don’t seem to support that theory. That said, sometimes these things happen when you get into exclusivity clauses with recruiters, so it may still be valid.
Ultimately, I think there’s too much detail missing to give a full review, but if you’re interested in a senior role in a company that does payment processing with what sounds like a Microsoft/Java technology mix, it may be worth trying to learn a little more. And when I say a little more, I really mean the basics, like “Who are you? Where are you located? What does this job pay?”
