Job summary

Superhuman is seeking a Back-End Engineer to build high-throughput services powering AI agent orchestration and real-time data pipelines. You’ll design core platform services and APIs connecting the AI engine to all product surfaces, collaborating with ML/AI, Product, and Front-End teams to deliver end-to-end AI-powered features.

The role spans the Go, Mail, Docs, and Enterprise products, with hybrid NYC hub or fully remote options.

Qualifications

• 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.

Responsibilities

• 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.
