Our Front-End engineers own the interfaces that put AI capabilities directly into users' hands: the Chrome extension and desktop app for Go (our proactive AI assistant), the editor and collaboration surfaces in Superhuman Docs, the inbox experience in Superhuman Mail, and the admin controls that let enterprises deploy it all at scale.This isn't typical front-end work. You'll build interfaces that stream and render AI-generated content in real time, design interaction patterns for inline agent suggestions that appear while users are writing, and create the tools that let anyone build and customize their own AI agents — no code required. The craft challenges are deep: orchestrating state across browser extensions, native desktop apps, and web surfaces; making agentic workflows feel instant and fluid; and shipping a consistent experience across a product suite that reaches millions of users.Superhuman's engineers have the freedom to innovate and uncover breakthroughs - and, in turn, influence our product roadmap. The complexity of our technical challenges is growing rapidly as we scale AI-powered features across every surface.
