About the Role

Alt is unlocking the value of alternative assets, starting with the $5B trading-card market. We let collectors buy, sell, vault, and finance their cards in one place. Our next frontier is real-time pricing at scale—the Alt Value that powers every trade, loan, and product on the platform. You are our founding Growth Engineer, turning today's experiments into instrumented, repeatable systems across both sides of the marketplace — sellers and buyers.

Responsibilities

Rebuild the submission funnel end to end, instrument every step, and run a real experimentation loop on it — A/B testing, and re-engagement for the users who exit without submitting.
Work out which channels bring in real users on both sides — lifecycle, SEO, AEO, paid, mobile ads — and build the machinery to scale the ones that work.
Instrument how Alt gets represented in ChatGPT, Claude, and Gemini answers, build the harness that measures it across a set of real collector queries, and treat the results as a channel with a dashboard.
Stand up an agent that reads the funnel — event stream, attribution tables, experiment results — and hands you the ranked list of steps where users are leaking, with a hypothesis attached to each.
Use models to generate and QA lifecycle content at variant scale — dozens of push, email, and SMS variants per test, screened for compliance and tone before a human reads them.
Put an MCP server over product analytics and attribution so "which channel produced last week's submissions" is a sentence, not another one-off query and a Slack thread.
Stand up clean attribution, consolidate our product analytics into a single source of truth, and modernize the messaging and deep-linking stack.
Turn push, in-app, email, and SMS into an owned, instrumented system rather than per-campaign setups — including SMS opt-in compliance.
Watch the balance across bidders, buyers, and sellers, and build growth into whichever side is weak.

Requirements

5+ years of engineering experience with strong backend (Python, Postgres, AWS or similar) and frontend (React, React Native, JavaScript/TypeScript) chops.
A track record of owning growth systems or product features from design to production.
Fluency with growth tooling and analytics — experimentation and A/B frameworks, product analytics (PostHog, Amplitude, or similar), attribution (AppsFlyer or similar), and lifecycle platforms.
A sharp instinct for funnels and instrumentation, and the patience to turn messy data into clean, trustworthy signal.
Comfort owning a north-star metric.
Strong collaboration and communication.
Familiarity with the collectibles space or alternative asset marketplaces.
Download the app, put a card up, make a bid, and try selling.
Pay attention to where the submission flow made you hesitate.
