The Opportunity

Superhuman is building the AI productivity platform that works everywhere people do
- and the back end is where the intelligence lives. On the Mail team, our Back-End engineers build the systems that power calendar, scheduling, and AI-driven workflows, from the real-time infrastructure behind Superhuman Mail to the services that connect our AI layer to users across desktop, web, and mobile.



This is backend work at the intersection of systems engineering and AI. You’ll join the Mail team at a pivotal moment: as "AI Home" in our product and new integrations raise the bar, we’re modernizing our calendar backend, including calendar syncing, notification infrastructure, and the APIs that serve every client. That architecture is what makes agent-based features, like meeting notes and scheduling agents, possible without slowing the product down. You’ll work in Go, Postgres, Kubernetes, and AWS, alongside a strong team of product engineers. Superhuman’s engineers have the freedom to innovate and shape the product roadmap. The complexity of our technical challenges is growing rapidly as we scale AI-powered features across every surface. You can hear more from our team on our technical blog.

- Design and build core platform services — task schedulers, session and conversation history, client-server protocols, and the APIs that connect our AI engine to every product surface.
- Work across the Superhuman product suite — whether that’s Go, Mail, Docs, or Enterprise — depending on where you and the team see the best fit.
- Collaborate closely with ML/AI, Product, and Front-End engineers to ship AI-powered features end to end.
