About AgentMail

About the role

Design APIs and abstractions that are intuitive for both humans and AI Agents Build high-performant, low-latency systems with the idea that agents are the end-users in mind

What they're looking for

  • You are highly technical: preferred you have prior experience shipping production software by real users as a software engineer at a tech company or startup. But hustlers are always appreciated
