Senior-Engineers

Why AI Is Hurting Your Best Engineers Most

The productivity story on AI coding tools has a flattering headline: senior engineers realize nearly five times the productivity gains of junior engineers from AI tools. More experience means better prompts, better evaluation of output, better use of AI on the right tasks. The gap is real and it makes sense.

But there’s a hidden cost buried in that same data. The tasks senior engineers are being asked to spend their time on are changing—and not always in ways that use their strengths well. Increasingly, the work that lands on senior engineers’ plates in AI-augmented teams is validation, review, and debugging of AI-generated code—a category of work that is simultaneously less interesting, harder than it looks, and consuming time that used to go to architecture, design, and mentorship.
