Software engineering is, among skilled professions, the one that travels with the least friction. The stack is the same everywhere: languages, frameworks, system design patterns, and CI/CD tools do not change from hub to hub. Resume matters less than a GitHub repository, visible open source contributions, and performance in a system design interview. Recruiters in hubs such as San Francisco, Seattle, New York, London, Berlin, Amsterdam, Toronto, Singapore, and Bangalore run the entire process in standard technical English. There are three legitimate and mature routes: a skilled visa sponsored directly by the company, a cross-border remote contract (more common at mid-level and above), and intra-company transfer between offices.
The choice of sub-domain changes the game for those who decide to emigrate. Backend distributed systems, platform engineering (DevOps/SRE), applied security engineering (AppSec), data engineering (Spark, dbt, Airflow), and applied machine learning engineering (LLM tooling, RAG, inference infrastructure) have shorter sponsorship queues and more aggressive relocation packages. Pure frontend web, mid-level iOS mobile, and management roles without an IC track record face a saturated internal market in every mature hub. Choosing a sub-specialization with structural scarcity matters more than choosing a hub.
