Do We Still Need Junior Developers in the Age of AI?
In the past, hiring a junior developer followed a familiar path:
· Get them comfortable with the existing codebase
· Assign simple tasks
· Gradually increase complexity and responsibility
· Conduct frequent code reviews with the team to guide their growth
It was a hands-on, mentorship-driven process — and it worked.
But today, in the era of AI, we must ask: Do we even need to hire junior developers when a senior, empowered with AI agents, can run a lean, hyper-productive team of virtual devs?
Why not just add another AI Agent instead?
The answer:
Yes, we still hire juniors — when we need to create a new development team.
Not just to build code, but to train them to become AI-native tech leads, capable of leading and coordinating development teams made up of AI agents.
We hire a junior so that in time, they can create and lead another whole team of AI agents themselves.
This shift demands a complete rethink of how we train junior developers.
We must teach more than just "how to code." We need to teach:
· How to collaborate with AI
· How to define architecture with AI
· How to review and refine AI-generated code
· How to lead AI-augmented teams
And yes — academic institutions must catch up. But let’s be honest: they’ll probably be the last to adapt.
