How Figma Works Under the Hood -- WebAssembly, WebGL, and Multiplayer Architecture

Figma's technical architecture is one of the most impressive in the industry: a C++ rendering engine compiled to WebAssembly, a custom WebGL/WebGPU rendering pipeline, and a server-authoritative multiplayer system that enables real-time collaboration. This module unpacks the technical decisions that make Figma possible, giving engineering candidates the knowledge to discuss Figma's unique challenges with depth and demonstrate genuine technical curiosity.
