If it’s a choice then no I don’t think it’s ethical. If it’s the only job you can get and you absolutely need it to survive or you’re facing threat of war from another country that’s a harder issue.
But assuming you aren’t forced to do it and it’s entirely your choice in time of peace: choosing to make weapons of war isn’t very ethical IMO. That’s a pretty huge assumption, though. Real life is rarely so simple.
