Senior Software Engineer, Front-End Infrastructure

Our Web Platform team is responsible for building and maintaining the critical systems that power Discord's frontend development across web, desktop, and mobile platforms. These systems support hundreds of engineers daily, process thousands of builds and deployments, and enable rapid feature delivery through robust tooling infrastructure. Through developing and operating foundational JavaScript build systems - including linters, bundlers, package managers, and CI/CD automation - our work allows internal developers to ship features quickly and safely while ensuring optimal performance, correctness, and developer ergonomics. This team also owns the localization and translation systems that power the strings and copy found across all of our apps and platforms.

As a Senior Software Engineer on this team, you will continuously improve our build tooling, developer workflows, and infrastructure - affecting the productivity of every frontend engineer at Discord and ultimately every user interaction on the platform!
