He wouldn't quantify his direct revenue impact, much as engineers who work on Borg and other infra don't. Or, he might point to a systems performance working group he helped chair and show that that working group improved performance of some syscall by n% (or added a new one that was n% faster) which when applied across all compute at Google has a wide revenue impact. (Or really he'd be at a leadership level where he'd need to show that the working group he lead did that a dozen times, but you get the idea).
