No, startups in Silicon Valley are starting to look at these certs because they realize how expensive poorly configured cloud infrastructure can be. It’s a skill that few people have at this point.
As a hiring manager for an infrastructure engineering team in a startup in the Silicon Valley, I have some opinion about the value of these certs.
I'd likely never hire an engineer with one of these certs and no relevant experience into a full-time position. I might offer an internship, but that's not a six-figure position.
Maybe not a "red flag" but I wouldn't be desperate to hire anyone with no experience, even in the Silicon Valley where competition for engineers is fierce. A headcount is a headcount as far as investors are concerned, so I'd rather have someone with more experience that also costs more.
Even still, I agree with the parent up above. A degree isn't strictly necessary, and if someone had the motivation, the talent, and the cert, I'd be willing to give them a chance as an intern.
