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.

• 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.

• 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.

• 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.
