Loved and adored: see what our customers say
On the Mail team, our AI Engineers build the platform behind our intelligent, agentic experiences, from the MCP layer that connects Superhuman to the tools people work in, to the personalization that makes the product feel like it knows you.
This is engineering at the intersection of backend systems and applied AI. You’ll build the tools and standards that let agents take real action for users, and help teams across Superhuman ship AI features faster. We use many models, from OpenAI and Anthropic to open source, and a single feature like Ask AI can route across several depending on the task. You’ll help us find the best model for each job, no matter who built it.
Superhuman’s engineers have the freedom to innovate and shape the product roadmap. You can hear more from our team on our technical blog.
