About the organization

This is a place for people who want to work at the frontier: an AI company building the infrastructure other AI companies run on not one bolting AI onto an existing product. We move fast go deep and are building the tools superintelligence will rely on to gather data from the web.

Responsibilities

• Own the growth surfaces end to end: signup activation onboarding and conversion
• Instrument the funnel run experiments and ship the changes that move real metrics
• Build full stack from the front end a developer first touches to the backend that powers it
• Treat conversion and activation as your number; you own it measure it and move it

Work close to the data form hypotheses test them and iterate fast on what works

What Were Looking For

• Youre a strong full-stack engineer whos worked on growth or PLG products

• Youve personally owned a conversion activation or funnel metric and moved it not just shipped features someone else measured

• You think like a scientist: hypothesis experiment measure iterate and youve run real A/B tests you can talk about including what you learned when they didnt go as planned

• Bonus if youve shipped in-product growth surfaces at a dev-tools or SaaS company (onboarding activation upgrade flows in-product guidance) or built conversion pages that measurably moved signups not just static pages that shipped

• Bonus for experience with our stack ( React Tailwind TypeScript Vercel PostgreSQL and the Anthropic Claude API) or for having built with LLMs in production: prompt engineering tool use inference pipelines

• Youve worked on developer-facing products SDKs playgrounds docs surfaces APIs and understand how developers actually adopt tools

• You have a track record of staying with your work long enough to see it through (we look for real tenure not a trail of short stints)

• You move fast and close the loop - youd rather ship measure and iterate than perfect on paper

A Note On Pace

We operate at an absurd level of urgency because the window for what were building wont stay open forever. If youve felt what scaling chaos is like at a company growing fast from early revenue to real scale youll feel right at home. If that excites you keep reading. If it doesnt no hard feelings but this role probably isnt for you.
