- Able to “see the whole chessboard” — from memory to metrics
- Pragmatic with a love for elegant automation
- Comfortable with fast iteration and ambiguity
Who We AreWe’ve built an AI marketing agent that’s getting a lot of traction. Over the last few weeks, referral volume is up 500%, and we literally can’t keep up with inbound from minimal sales efforts.
We need a couple of great engineers to help us scale this to the moon. With just a few months of focused, high-leverage execution, we believe we can reach multi-million ARR.
We’re offering a competitive equity + cash comp package for this stage — and the chance to be in on the ground floor of something really exciting.
Let’s BuildIf this sounds like you, and you're ready to move fast and build, reach out. We’d love to hear from you.
