About the role
Alt is growing! This role leads the charge on new user count: how many collectors land on Alt, how many make a first submission or a first bid, and how many come back without being asked. That number is the job. Everything else in this description is downstream of it.
What they're looking for
- You've owned a growth surface, marketplace funnel, or PLG motion and moved the number on it. Roughly 5+ years of building, but we're reading the work, not the years
- You own a number today and can name it, its baseline, and where you took it, on the first ask
- Strong data fluency. SQL and Python, plus PostHog, Amplitude, Mixpanel, Statsig, Eppo, or similar. You pull your own numbers and you've built the instrumentation behind them
- Experimentation in your hands, not on your résumé. You've designed the test, set the decision rule before it ran, and made the call on partial data
- Deep understanding of two-sided marketplace dynamics. Supply and demand, liquidity, and what happens to one side when you push the other
- You've built real things with AI , not just used it. Agents, skills, MCP servers, connectors, internal tooling people depend on
More about this role
Alt is unlocking the value of alternative assets, starting with the $5 B trading-card market. We let collectors buy, sell, vault, and finance their cards in one place and we are backed by leaders at Stripe, Coinbase, Seven Seven Six, and pro athletes like Tom Brady and Giannis Antetokounmpo. Our next frontier is real-time pricing at scale—the Alt Value that powers every trade, loan, and product on the platform.

This is a builder seat, not a product management seat. You own the seller submission funnel, buyer search and discovery, and the experimentation infrastructure underneath both, and you own them the whole way: you find the drop-off, you write the code, you ship it behind a flag, you read the result, you keep it or you kill it.
What this role is not: writing PRDs for someone else to implement, running roadmap ritual, managing a pod, or translating between engineering and the business. If that's the shape of your...
