Nothing screams "danger pay" quite like being told you'll be wrapping a COBOL mainframe system. For context, COBOL is a language from 1959 that's still running critical banking and government systems because nobody dares touch them. Creating a wrapper means you're building a modern interface around ancient, undocumented spaghetti code that predates the moon landing. The "then you can leave" energy is perfect because this is genuinely one of those nightmare scenarios where the compensation better be astronomical. You're essentially being asked to become an archaeologist, translator, and diplomat all at once—deciphering cryptic business logic written by programmers who are probably retired (or worse, still maintaining it). The code comments? Non-existent. The documentation? "Ask Jerry, but he left in 1987." Fun fact: COBOL still powers about 43% of banking systems and processes roughly 95% of ATM transactions. So yeah, the pay should be good, because you're literally keeping civilization's financial infrastructure from collapsing.
