Engineering industry stops hiring junior developers, dismantling the career pathway that creates senior engineers

A job listing for a junior Python/Django developer in a public engineering Slack community attracted replies mocking the posting ('lol, companies still hire juniors?', 'just use Claude bro'), leading the poster to delete it after twenty minutes. The post received forty-seven laughing reactions.

The shift reflects a decision that junior engineers are obsolete, driven by industry vibes and vendor pitches rather than research or analysis. Senior engineers got their start through internships, graduate programmes, or first jobs where experienced colleagues mentored them—a pathway the industry is now dismantling.

Cutting junior hiring does not save money long-term: every senior engineer was once a junior. Without hiring juniors, the pool of experienced engineers depletes over time. A CTO running a team of twelve senior engineers with zero juniors believes this is sustainable ('We're running at 3x the output of a team twice our size'), but when departures occur, there is no pipeline to fill gaps and the market has no candidates because other companies cut their pipelines too.

Juniors provide redundancy by learning systems from scratch, which means someone always has recent context on onboarding gaps, undocumented tribal knowledge, and fragile codebase areas. When an entire team is senior, people assume everyone understands everything, so basic questions go unasked and knowledge walks out the door when someone leaves.
