Where it is strong
- • Salaries roughly a third below northern Europe for similar engineering skill
- • Strong solar, water-scarcity and smart-city demand across Spain
- • Attractive enough that senior international hires say yes
Watch out for
- • Incorporation and permitting are slower and more paperwork-heavy
- • Spanish (and often Catalan) is needed for public-sector work
