Engineering remains the most resilient sector despite the AI boom

SignalFire, which analyzed career trajectories across 80 million companies, found that engineering hiring dropped only 11% compared to 2019 levels, significantly outperforming the broader 25% decline in total tech industry recruitment. At major firms including Alphabet, Meta, and Nvidia, engineers accounted for 55% of all new hires in 2025, up from 46% six years ago. Early-stage startups exhibited an even sharper trend, increasing their engineering headcount by 7% over the same period.

This resilience challenges the hypothesis that AI tools will render human coders redundant. Nvidia CEO Jensen Huang has dismissed the replacement theory entirely, noting that AI agents have made his engineers busier by accelerating the development cycle and enabling faster iteration on new ideas. Experts point to the Jevons paradox to explain this phenomenon: as AI increases individual productivity, the demand for complex technical work expands rather than shrinks. According to SignalFire’s head of research, Asher Bantock, the reality on the ground contradicts the layoff rationales circulating in boardrooms, as engineering talent remains a critical resource for companies scaling new capacities.
