I'd let the material science engineer figure that one out too. No way in hell would I risk my ignorance of building maintenance be the cause of thousands of deaths.

One thing I learned in getting my engineering degree is that it’s unethical to practice engineering in an area you don’t understand. No way would I ever try to apply my software engineering skills to a materials problem

I feel it's only unethetical if there are "real" stakes on the line. E.g. Where people can get hurt. I don't mind a mechanical engineer writing code for a company that makes the zillionth vapid webapp nor do I mind a software engineer designing a mechanical watch.

The materials engineer can give you a great material. They can't design a system to monitor said material for defects.

S3 bucket had public access enabled... we asked a software engineer to do something that they're not the expert in.
