AI tools have changed what junior engineers do. How do you rethink hiring and growth?
Treat junior engineers as your future senior bench, not as cheap throughput. Size early-career hiring from the senior pipeline you will need, redesign the work so juniors still build judgement alongside AI coding assistants, hire for reading, debugging and review, and promote on diagnosis, not output.
Answer
Short answer
Junior engineers are where your future seniors come from. AI coding assistants now do much of the bounded work juniors used to learn on, so the risk is not that juniors are useless but that nobody gets the apprenticeship. Size early-career hiring from the senior pipeline you will need in four or five years, redesign the work so it still builds judgement, hire for reading, debugging and review, and change the ladder to reward diagnosis rather than output.
