What recruiters should know
Julia has been downloaded over 100 million times and has 12,000+ registered packages. JuliaCon Global 2026 is active. Julia's primary value proposition is high-performance numerical computing — it approaches C speed while feeling like Python. Premium niche: quantitative finance (Jane Street-adjacent), climate science, aerospace, ML research, and pharmaceutical simulation. Career ROI: smaller job market than Python but niche salaries can be very high, especially in quant finance and research. Growing adoption in EU defence contracts and NASA computational projects.
