Growth Engineer - Alt

About the 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. We’re looking for our founding Growth Engineer to build a predictable growth engine across both sides of the Alt marketplace, sellers and buyers. You won’t just run marketing tests; you’ll turn today’s one-off experiments into real, instrumented, repeatable systems that move our north star: unique submissions. This is not a marketing hire and not a generic backend hire. It’s a technical owner who understands growth levers and can build them. You’ll partner tightly with our founder and marketing lead, own the funnel end to end, and grow into leading the growth function over time. If you think like a PM, build like an engineer, and want a high-ceiling seat with real ownership, you’ll thrive here. What You’ll Do Here: Own the activation funnel: Rebuild the submission funnel end to end, instrument every step, and run a real experimentation loop, including A/B testing and re-engagement for users who exit without submitting. Scale acquisition channels: Figure out which channels actually acquire users on both sides (lifecycle, SEO, AEO, paid, mobile ads) and build the machinery to scale the ones that work. This includes agentic optimization: how Alt ranks and shows up in ChatGPT, Claude, Gemini, and other assistants. Fix the data + attribution foundation: The unlock for everything else. Stand up clean attribution, consolidate our product analytics into a single source of truth, and modernize our messaging and deep-linking stack so we can finally tell what’s moving the needle. Build lifecycle infrastructure: Turn push, in-app, email, and SMS into an owned, instrumented system rather than per-campaign setups, including SMS opt-in compliance. Balance the marketplace: Watch the balance across bidders, buyers, and sellers, and build growth into the weak side. This is a perfect fit if you… Own the engine, not the tickets: You step back, instrument the full funnel, find the real blockers, and go after them. You don’t wait to be handed a backlog. Speak growth and code fluently: You’re deeply technical and can build, but you’re just as comfortable talking about levers, funnels, and CVR like a PM. Are excited about Alt specifically: You’re drawn to marketplaces, collectibles, and alternative assets, and you have a high ceiling and want to grow into leading a function. Hold yourself to the numbers: You’re comfortable owning a north-star metric and secondary metrics with the same weekly-reported discipline we hold marketing to. What You Bring to the Table: 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, including experimentation/A/B frameworks, product analytics (PostHog, Amplitude, or similar), attribution (AppsFlyer or similar), and lifecycle platforms A sharp instinct for funnels, instrumentation, and turning messy data into clean, trustworthy signal Strong collaboration and communication. You write great docs, ask smart questions, and give thoughtful feedback Bonus: familiarity with the collectibles space or alternative asset marketplaces What You’ll Get From Us: Direct impact: A founding seat owning the growth engine for the whole marketplace, a ground-floor opportunity with a metric the whole company watches. Autonomy: High-trust environment with ownership over critical, revenue-driving surfaces and the freedom to make product-grade bets. Stipends: $100/mo WFH, $200/mo wellness, and WeWork office access. Benefits: 401(k), flexible vacation, generous parental leave, and top-tier healthcare (HSA included). Compensation : $160,000-$180,000
