What about GAAP/IFRS? How do you endow these software engineers with knowledge of common patterns of fraud or leaks so they can actually write the correct software to find them automatically? How do they identify material misstatements? You also seem confused; COBOL might be used, but it isn't the only tool available to accountants working for the government. COBOL is a straw-man. What you're describing here—software engineers who presumably have training in accounting—already exists, and they work inside and out of the government. This is an existing career path. You're speaking about this as though you know a better way to do something, but it's already happening, and has been for years. Accountants aren't writing 62 year old programming languages waiting to die in their chairs while the world continues to progress without them. Accounting just about anywhere you find it is already accomplished by accountants, some of them technically trained, as well as data scientists and software engineers. It's an interdisciplinary collaboration in any serious organization.
