The OpportunitySuperhuman 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. You’ll work in Go, Postgres, Kubernetes, and AWS, alongside a strong team of product engineers.



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. As a Back-End Engineer, you will: Build and operate high-throughput production services that power AI agent orchestration, connector integrations, and real-time data pipelines. 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. Collaborate closely with ML/AI, Product, and Front-End engineers to ship AI-powered features end to end. Build and evolve infrastructure as code, targeting high availability for both consumer and enterprise customers. Contribute to an engineering culture with a strong emphasis on documentation, testing, and reliability. Qualifications5+ years of experience in back-end development, with strong fundamentals in algorithms, data structures, and system design. Experience building, deploying, and debugging production systems at scale. Experience with AWS or other cloud platforms (GCP, Azure). Comfort working with AI-powered systems — whether that's building infrastructure for LLM-based features, managing agentic workflows, or integrating with ML pipelines.



Prior experience building backend services for AI products 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. Demonstrated ability to work independently, manage priorities across multiple projects, and collaborate effectively with cross-functional teams.
