Founding Growth Engineer

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:
