In hardware engineering, there are many roles: for example PCB Design engineer, FPGA engineer etc.
Can we ask questions like:
on Electrical Engineering Stack Exchange?
If not, is there any other Stack Exchange site to ask such questions?
I'd try on chat. I don't think it would be well-received on the main site. For example, searching for engineer skill is:question will show a few similar questions, all of which are closed.
There also was a question about how to ask for career advices here, posted 10 years ago, and the answer was the same: chat.
Of course, chat drags much less people.
I also tried to check if there are other sites on the SE network where this kind of questions would be appropriate. The workplace is dedicated to career-related topics, but it seems asking about skills required for a specific job is off-topic according to this answer (written by an ex-mod of the workplace site). There is also a specific close-reason on this site that confirms it is off-topic: "Questions asking for advice on a specific choice, such as what job to take or what skills to learn, are difficult to answer objectively and are rarely useful for anyone else. [...]"
So, apart from chat, I don't think it can be asked anywhere on Stack Exchange. But I'm pretty sure there are discussion forums outside of SE where you could ask this.
