Spain is running one of Europe's largest renewables build-outs: record shares of the country's electricity now come from wind and solar, and the pipeline of new projects keeps hiring engineers, project managers and technicians across the whole map — this is one of the few white-collar sectors where the jobs are not concentrated in Madrid and Barcelona. The employers span the full chain: Acciona and Solaria developing and operating plants, Nordex manufacturing wind turbines in Spanish factories, Elecnor building the infrastructure, Redeia running the grid, and the utilities and majors — Iberdrola, Endesa, Naturgy, Repsol, Cepsa — staffing their transition businesses.
Language splits by altitude. Site, construction and O&M roles are Spanish-first because the crews are; the multinationals' engineering, development and corporate teams — and anything with international project scope — frequently work in English. A note on coverage: Iberdrola's careers feed currently yields few adverts relative to the company's real hiring, so treat its count here as a floor, and Siemens Gamesa is not yet indexed at all.
