Founding Engineer
AgentPhone, San Francisco, California +1
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.
You don't need any telephony experience. Telecom is a weird, adversarial, undocumented world. Carriers filter messages with rules they won't publish. Countries block traffic at the network level. Apple decides your iMessages are spam and won't tell you why. Nobody comes in knowing this stuff. What we need is a go-getter who can use AI extremely well to learn fast, ship fast, and figure things out that most companies gave up on decades ago. That's the moat, and you'd be building it.
What you will do
- Build and scale core telephony infrastructure: SIP trunking, real-time voice (LiveKit), call routing, and media handling
