CTO
Chief Technology Officer
ELI5 — The Vibe Check
The person who gets blamed when the technology doesn't work. The CTO sets the technical vision, picks the stack, hires the engineers, and explains to the CEO why the rewrite will take 6 months (it'll take 18). In startups, the CTO also writes code. In big companies, the CTO writes emails.

The Chief Technology Officer is the executive responsible for an organization's technology strategy, infrastructure, and engineering teams. The role varies: in startups, CTOs are often hands-on architects; in enterprises, they're strategic leaders focused on technology roadmaps, vendor relationships, and engineering culture.
