SWE4, Netflix JavaScript Foundations — language-level DevEx across the fleet
Join Netflix's JavaScript Foundations team in Warsaw, owning language-level strategy (dependency management, supply chain security, TypeScript) that unifies browser and Node.js runtimes across the whole company. This is an influence-and-alignment-heavy role — 'code is a very small slice of this team's impact' — focused on driving adoption of tooling/patterns across many internal teams rather than building a single product.
