Founding Product Engineer

AgentMail is building the communication infrastructure for AI agents, giving agents their own email identities and infrastructure to send, receive, and act on email programmatically. The company has processed hundreds of millions of emails and serves developers building agentic products. The Founding Product Engineer will help define what using AgentMail feels like to customers. The role involves owning products from an ambiguous customer problem to something developers use every day, with significant autonomy and an equally high bar for ownership. It is not a role where a PM hands over a spec and a designer hands over a Figma file. Work is in-person in San Francisco, CA.

Responsibilities

Build products end-to-end across frontend experiences, APIs, backend services, data models, and infrastructure; talk directly to customers, interview developers, watch them use AgentMail, and analyze support conversations and usage data; turn customer problems into products by deciding what should be built and which problems are worth solving; shape the developer experience from sign-up to getting something useful into production; prototype quickly, turning customer conversation ideas into usable solutions within days; sweat the details of how products look, feel, and behave, influencing design and interaction patterns; help define the product engineering culture as one of the earliest engineers focused on product

Requirements

Exceptional frontend engineering skills with strong product and design instincts; strong backend skills, comfortable with APIs, backend systems, databases, queues, and distributed systems when necessary; ability to turn a vague problem into a product without waiting for a detailed spec; enjoys talking to customers and separating what they ask for from the underlying problem; able to contextualize technical decisions in terms of customer and business impact; strong opinions about products; comfortable moving quickly, shipping imperfect things, learning from usage, and iterating; extremely high agency, fixing things that are broken or missing

Nice to have

You don't need to have been called a "Product Engineer" before; interest in whether you've built things people love
