Anthropic's own data: junior technical hires fell from 27% to 9% as agent hours hit six times human hours

Anthropic published "How employment is changing at Anthropic" on October 16. It draws on internal data covering employment, AI use, output, employee surveys, calendars and hiring records, plus 17 employee interviews.

The share of junior-level employees in Anthropic's technical departments slipped from 21% to 14% since early 2025, and junior technical hires fell faster, from 27% to 9%. Around a third of ML managers and a fifth of software engineering managers said they were hiring less because of AI.

On the agent side, the report says that in employee-directed interactive sessions, agents worked six times as many hours as the people directing them by August. Code commits per engineer are at 5x their velocity of six months earlier. Coding-focused agent sessions by non-technical employees went from 2 a month in August 2025 to 90 in May 2026.

The constraint is human attention. Anthropic says Claude sessions spend around 80% of their time idly waiting for human input, and that reading everything their agents produce would take even non-technical employees half their work week. Hiring managers now put more weight on autonomy and judgment than on specific technical expertise.
