Dude shipped flamegraphs (which he also created in 2011) for cloud GPU loads and persuaded internal stakeholders to release the code as open source.
The "interviewed by the WSJ" line is for managers. Reading between the lines, I'd say he did really well and, if he didn't do better, it's because the organisation didn't let him.

It’s a green flag for hiring managers for sure. Even a lot of valued employees wouldn’t be allowed to represent a big company to the WSJ for various reasons, even with a PR person sitting next to them.
I can’t tell if he is just good at self promotion or he is just good. But that’s always the case at bigcorp.
Flamegraph is literally just a perl script that visualizes the stack traces collected by perf/dtrace (kernel). It's a good tool though but it doesn't need to be oversold for its capabilities, the hard work is done by the kernel. And honestly, many times it is not that useful at all and can be quite misleading, and not because of the bug in the tool but because how CPUs are inherently designed to work.

The last few sentences to me read like he knows for sure that the organisation is actively working against what he sees as his important goals. Carefully worded (and likely personal lawyer approved) to avoid burning the bridges as he mic-drops and deftly avoids having the door hit him in the arse as he struts out.
