Government. About 25% of my job. No day to day mainframe development, but we do need to update some logic for new policies and regulations.

There’s not much maintenance work. There are very few bugs, as the core applications have been running for decades, most come up with interactions to external services.

Any major development projects are only in service of lower overall COBOL development time, like transitioning some business logic to database updates.

And there is a decommission plan for the mainframe, so plenty of work helping that team.
