My mother and her husband are COBOL devs for a US state government. She works on the health insurance side for teachers and other state employees. Think claim processing.

Lots of batch jobs running at night. Their alert system is an actual human who calls my mom when jobs fail in the middle of the night.

It's high paying for the city they live in, but not high paying for software development. They will both have full retirement and healthcare for life, assuming the government can fulfill it. They are both fully remote since COVID too.

She's also worked for state lottery, teacher's retirement system and DOT.

edit: she says they have a SQL database, but mostly store in IBM IMS
