About the role
We are looking for a Founding Product Engineer with 0-7 years of experience to define what using AgentMail feels like for the developers building the most ambitious AI agents. You are a high-agency, full-stack builder with strong product and design instincts who has owned projects from 0 to 1 in a startup environment. AgentMail (YC S25) is rebuilding email for AI, has already processed hundreds of millions of emails, and needs builders who can turn ambiguous customer problems into products developers love. You will work directly with the founders and help shape the product engineering culture from day one.

- Prototyping quickly and shaping the developer experience from sign-up to production
- Helping define AgentMail's product engineering culture and design standards as one of the earliest engineers
