Can vibe coding replace junior developers?
Vibe coding tools like Cursor and Claude Code have automated the typing-heavy tasks that once defined junior developer work, but they haven't made the role obsolete. The junior role has shifted from writing first drafts to critically reviewing AI-generated code, spotting security flaws, missing permission checks, and architectural mismatches. The key failure mode for juniors is accepting generated diffs without understanding them. Seniors must adapt mentorship to focus on architecture and prompt strategy rather than line-by-line syntax review. Hiring signals have also changed: the ability to audit a vibe-coded diff for real bugs matters more than whiteboard coding. Teams that skip hiring juniors lose their pipeline for producing future seniors.
