Make everyone on your team an engineer. Backed by Y Combinator.
About the role
Lane 1: Experienced operator — You've already driven growth at a strong startup and want much more ownership, scope, and upside as the person who builds the motion from scratch. Lane 2: Exceptional emerging builder — Less conventional experience, but you've already run experiments that worked, write unusually well, move fast, and show real evidence of ownership. We care about slope and output over pedigree.
What they're looking for
- A track record of driving real growth — pipeline, signups, or revenue — ideally at an early-stage startup
- Roughly 1–5 years is a good baseline, but we'll flex for someone unusually strong
- Ability to run growth full-stack with high autonomy: strategy, execution, and the tooling to make it happen
- Strong writing and taste — you can make a page or a cold email that actually converts
- Comfort with data: you can instrument a funnel, read it, and act on it
- High agency: you notice problems, propose solutions, and drive things to completion

This is a builder's growth role, not a manage-an-agency role. You should already use AI tools by default — using Claude, Codex, and agent workflows to run experiments, build landing pages, wire up automations, and move faster than a whole marketing team, without lowering the bar.
- Own the top of the funnel end to end: outbound, content, launches, lifecycle, and paid experiments.
Talk to users and prospects constantly , find what actually drives adoption, and double down fast.
- Build the growth engine yourself — landing pages, sequences, analytics, and internal tooling — instead of waiting on anyone.
- Run a high volume of experiments, kill what doesn't work, and scale what does.
- Help set the growth bar , the messaging, and the pace of the company.
- This is not a role where you can coast. It requires deep ownership, agency , and responsibility.
- A track record of driving real growth — pipeline, signups, or revenue — ideally at an early-stage startup.
