The Opportunity

Superhuman is building the AI productivity platform that works everywhere people do, and Superhuman Mail is central to how people communicate and get work done. Today we are...The fastest email experience in the world

• Loved and adored: see what our customers say

On the Mail team, our Back-End engineers build the real-time systems that power our product, from the infrastructure behind every message flow to the AI layer that keeps work moving fast and intelligently.

This is backend work at the intersection of systems engineering and AI. You'll build the services that allow our agentic workflows to scale in Superhuman Mail, and the real-time infrastructure that connects our AI layer to users across every surface. You'll also help design the infrastructure that lets anyone create custom agents and publish them to a marketplace reaching tens of millions of users.

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 to allow our systems to scale
• 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.

Qualifications

• 8+ 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).
• 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.
