Software Engineer 4, Javascript Foundations · Engineering

Netflix is one of the world's leading entertainment services, with over 300 million paid memberships in over 190 countries enjoying TV series, films and games across a wide variety of genres and languages. Members can play, pause and resume watching as much as they want, anytime, anywhere, and can change their plans at any time.

Who We Are We are the JavaScript Foundations (JSF) team in Warsaw. We are key partners in building the "UI Paved Road" at Netflix, operating within a global, virtual organisation that shepherds JavaScript across the entire company — from the browser to Node.js services powering our studio and streaming systems.

Our Mission Our product isn't a single app — it’s the developer experience itself. While our sibling teams focus on specific layers of the stack — Node.js Platform on server runtime, UI DevEx on browser runtime, and Design Systems on visual components — we tackle the foundational language-level challenges that unify them all. We own the strategy for dependency management, supply chain security, and TypeScript, ensuring the ecosystem remains healthy, secure, and modern across both browser and server.

Why It Matters At our scale — serving hundreds of millions members — "foundational" means high-impact. Whether it’s automating annual Node.js LTS migrations for thousands of services or defining the patterns for how we share code across the fleet, we measure our success by the collective velocity of every UI engineer at Netflix. We tackle language-level problems so they can focus on entertaining the world.
