[Hiring] AI Engineer @Superhuman

Role Description

We are only able to consider candidates based in Argentina, Brazil, and Mexico. For candidates based in these countries, Superhuman offers a fully remote working model for this particular role on the Mail team. This gives team members plenty of focus time and the flexibility to do their best work from wherever they're based, while staying closely connected to a collaborative, tight-knit team culture.

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 by our customers.

On the Mail team, our AI Engineers build the platform behind our intelligent, agentic experiences, from the MCP layer that connects Superhuman to the tools people work in, to the personalization that makes the product feel like it knows you. This is engineering at the intersection of backend systems and applied AI.

As an AI Engineer, you will:

• Build and evolve Superhuman Mail’s MCP: new tools, new standards, and new ways for agents to deliver value to end users
• Design and ship agentic workflows and personalization features at scale
• Build evaluation systems that measure quality and catch regressions as prompts, models, and tools change
• Help choose the right models for each task and keep exploring new ones
• Partner with teams across Superhuman to give them the AI building blocks they need
• Ship quickly while learning, and adjust course as the industry shifts
• Help shape our modeling approach, including what data to collect and how to generate it

Technologies we use: Go, Postgres, Redis, Kubernetes, AWS, TurboPuffer.

Qualifications

• 4-6+ years of software engineering experience with a strong backend foundation (Python or TypeScript is great, Go is a plus)
• Hands-on experience building and shipping LLM-powered features in production, such as agents or agentic loops
• Experience building evals to measure and improve LLM quality
• Familiarity with MCP servers or tools, or eagerness to dive in
• Working ML knowledge to reason about model selection and tradeoffs. We’re looking for builders, not researchers
• Comfortable with ambiguity and quick changes in direction
• An AI enthusiast who uses AI to boost your own productivity and your team’s impact
• Strong ownership, a bias to action, and a growth mindset
