Phone Numbers for AI Agents. Backed by Y Combinator.
About the role
You'll be our first engineering hire, working directly with the two founders (CEO and CTO, also brothers, we argue efficiently). Your job is to make the company better every single day: better product, better infrastructure, better customer experience. You'll ship code, talk to customers, and own problems end to end.
What they're looking for
- A go-getter. You see a problem, you own it, you fix it, no one has to ask
- You use AI tools extremely well and move faster with them than most engineers think possible
- You've shipped real software that people actually use
- Comfortable talking to customers directly and turning their problems into product
- You move fast in ambiguity and take full ownership without process or specs
- No telephony experience required. We'll teach you everything, or you'll figure it out with us
More about this role
AgentPhone gives AI agents phone numbers. Voice, SMS, and iMessage through one API.
The oldest address on the internet is a phone number. Every business, every bank, every human still runs on it. But the entire telephony stack was built for humans dialing humans. AI agents are about to make and receive millions of calls and texts, and the infrastructure underneath them was never designed for that.
We're building it. Over 100 companies use AgentPhone today to provision numbers, place and receive calls, send texts and iMessages, and stay compliant with carrier regulations, all from a single API and MCP server. We're backed by Y Combinator (P26) and investors including Swift Ventures, Singularity Capital, Leonis Capital, Rebel Fund, Pioneer Fund and more.

You don't need any telephony experience. Telecom is a weird, adversarial, undocumented world. Carriers filter...
