EF English score, 86th of 123 countries
Monthly starting point for a senior engineer through us
Software and IT services revenue reached about $919 billion in the first five months of 2026, up 10.3 percent year on year, across roughly eight million people in software development. The AI competition for engineers is intense: Tencent raised technical recruitment 36 percent in 2026, AI roles account for more than 60 percent of Alibaba's hiring and more than 90 percent of Baidu's campus intake. Beijing holds 19 of the country's top 50 AI companies, Shanghai 14, with Shenzhen and Guangzhou holding 10 between them.
China scored 464 in the 2025 EF English Proficiency Index, 86th of 123. Engineering talent is exceptional and English is genuinely a constraint for most of it. Teams that succeed here run written-first, keep specifications precise, and put a bilingual lead between the team and the business.
Employer contributions run 30 to 35 percent including the housing fund and are set city by city, with the contribution base banded between 60 and 300 percent of the local average wage and reset every July. Since September 2025 any agreement to waive social insurance is void, and an employee can resign on that basis and claim severance. Budget from the city, never from a national average.
