They don't need to because that's usually not what the job calls for, but I would think most people who call themselves software engineers believe they would be able to work at a job where they wrote FORTRAN instead of Python. It's just another programming language, you just have to spend a month to learn it. Assembly is just another programing language. Opcodes is just assembly without syntactic sugar. But of course that's not what my job calls for today, but if it did, it's not really any different in my mind from any new job where I'm doing something different, but just applying my software skills slightly differently.
