Software Engineer, Front-End

The Opportunity

Superhuman is building the AI productivity platform that works everywhere people do — and the front end is where it all comes together. 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.

Qualifications

• 7 years of experience in front-end development, with expert-level knowledge of TypeScript (and/or JavaScript), HTML, and CSS, extensive experience with ReactJS (or similar UI frameworks) and modern web client development and testing tools.
• Excellent software engineering fundamentals, including knowledge of algorithms and data structures.
• Comfort working with AI-powered features — whether that's building UI for LLM-generated content, streaming responses, or agentic workflows. Prior experience integrating AI/ML into product surfaces is a plus.
• Fluency with AI coding tools (Copilot, Cursor, Claude Code, etc.) and a point of view on how they change the way teams build software.
• Experience with browser extensions, cross-platform web clients, or shipping front-end code across multiple surfaces (web, desktop, mobile) is a plus.
• Deep understanding of continuous integration and delivery methods.
• Strong product instincts — you care about the end-user experience and strive to ensure high quality.
• Ability to work independently with minimal guidance, proactively manage priorities across multiple projects, and collaborate effectively with cross-functional teams.
