AI Engineer (Superhuman Mail) - US
About The Position
Superhuman is hiring an AI Engineer for the Superhuman Mail team. The role builds the platform behind intelligent, agentic experiences, including the MCP layer that connects Superhuman to users’ tools and personalization that tailors the product. It combines backend systems engineering with applied AI, creating tools and standards that let agents take action for users and help teams across Superhuman ship AI features faster. The team uses models from OpenAI, Anthropic, and open-source providers, selecting models for specific tasks. Engineers have room to innovate and influence the product roadmap. The position involves developing Superhuman Mail’s MCP, designing agentic workflows and personalization features, building evaluation systems, choosing and exploring models, and partnering with other teams on AI building blocks. The ML-leaning variant may also help shape the modeling approach, including data collection and generation. The team’s technologies include Go, Postgres, Redis, Kubernetes, AWS, and TurboPuffer. The role is remote-flexible, with a hybrid option for people based in San Francisco, New York City, or Seattle. Superhuman encourages applicants to share their knowledge, experience, goals, and superpower.
