What recruiters should know
Ruby hovers at ~6% developer usage (Stack Overflow 2025) and ranks 27th on TIOBE (Jan 2026). Entry-level demand has structurally declined since the 2015–2018 bootcamp era, but senior/staff Rails engineers remain a scarce, well-paid niche (senior remote salaries $160K–$220K+). Supply shortfall pushes salaries upward for experienced practitioners.
