Superhuman is building the AI productivity platform that works everywhere people do — and the back end is where the intelligence lives. Our Back-End engineers build the systems that power AI agents across the entire product suite: the scheduling layer that manages getting all your agents to run at the right time in Go the real-time infrastructure behind Superhuman Mail the collaboration engine in Coda Docs and the enterprise controls that let organizations deploy AI safely at scale.

This is backend work at the intersection of systems engineering and AI. You'll build the services that make agentic workflows possible — session history task scheduling client-server protocols and the real-time infrastructure that connects our AI layer to users across every surface. You'll design the infrastructure that lets anyone create custom agents and publish them to a marketplace reaching tens of millions of users. And you'll tackle the hard scaling problems that come with running AI-powered features across consumer and enterprise customers simultaneously.

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.

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.

• 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.

• 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.

• Mentor and grow junior engineers on the team.

• 5+ 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.

• Experience with real-time systems event-driven architectures or high-throughput API design is a plus.

• Deep understanding of CI/CD and infrastructure as code.

• Demonstrated ability to work independently manage priorities across multiple projects and collaborate effectively with cross-functional teams.

• Strong product instincts — you care about the end-user experience and can make good tradeoffs between speed and reliability.
