Advice for an older software developer looking for a change

My father is nearly 70. He works as a Cloud DevOps engineer for a large hospital. He seems really troubled with his current job, especially the fact that the people he work with don't value good engineering (my interpretation). He wants to move to a more tech/engineering driven company, but obviously with his age this is tough. He always talks about how he wants to move to a better job, but then says there's no point at his age. I do think he's a really competent engineer (I say this as, I think, a fairly competent software engineer myself, currently working at a major-ish tech company), and so I'd like to see him work somewhere he can thrive but worry it might be too late. Any advice on this?

Edit: Don't mean to be cynical, but as a potential plus, he does look quite young for his age (I'd say a solid 10-15 years)
