Tech layoffs have been attributed to AI, but data from venture firm SignalFire tells a different story. According to SignalFire, engineering jobs are more resilient than thought, with a 11% decline in hiring compared to 2019. Engineers made up 55% of new hires at large tech companies in 2025, a significant increase from 2019. This challenges the notion that AI is replacing engineers, and suggests that the industry needs more talent. Why it matters: The resilience of engineering jobs may indicate that AI is not as pervasive as some experts fear, and could have implications for the future of work in tech.
