GTM Engineer

Location: San Francisco, CA Type: Full-time, on-site

COMPANY OVERVIEW

AgentMail is building the communication and identity layer for AI agents.

Agents are starting to do real work, but they still lack basic infrastructure humans already have: persistent identity, reliable communication, permissions, memory, and a system of record. AgentMail gives every AI agent its own programmable inbox.

Developers use our API to create inboxes, send and receive email, manage threads, parse messages into structured data, route webhooks, attach domains, and build agents that can communicate across the internet.

We're backed by Y Combinator and have raised $6M led by General Catalyst, with support from the founders of Ramp, Supabase, and HubSpot, as well as Paul Graham.

We're early, moving fast, and building in a category without a playbook. If you want to help define core infrastructure for the agent era, we'd love to meet you.

TLDR

We're hiring a GTM Engineer to build the machine behind AgentMail's growth: the data pipeline, the outbound engine, and the source of truth the whole company runs on. This is a build-and-own role, not a support role.

WHAT YOU'LL DO

Own the growth data layer end to end: instrument the funnel, enrich every signup, and build the dashboards the company treats as the source of truth
Turn our best customers into ten more: lookalike modeling, automated outbound, LinkedIn plays, and surfacing champions and buyers inside companies already using us

TLDR: we are seeing a surge in market demand as agents become real first-class citizens of the internet, and we are aggressively hiring in order to keep up. We're coming up with solutions in a problem space where no one in Silicon Valley knows the answer to either: how to build something agents want. If you like owning things 0 -> 1, lets chat.
AgentMail is building an API designed to give inboxes to AI agents and be the sole identity + communication provider. It isn't AI for your email, it's email for your AI.
We’re looking for a founding engineer with strong backend and infra instincts to help build the primitives agents will use to communicate, authenticate, and operate in the real world. This is a role for someone who likes systems work: APIs, distributed infrastructure, reliability, developer tooling.
Company highlights:
- World-Class Team: Founded by a team of experts in their own respects(Quant, SWE, Private Equity), the team has top-tier talent from startups and big companies alike, with backgrounds from Optiver, NVIDIA, Amazon, Modern Treasury, KKR.
- Hypergrowth: We’ve doubled our user count every 2 weeks since January, and don’t plan on slowing down any time soon. As agents will outnumber humans very soon, we see this multiple changing in the range of orders very soon.
- Competitive-edge: We are the sole identity provider for agents. Just like you have a Gmail, agent’s will need an AgentMail.
