Note: The job is a remote job and is open to candidates in USA. Alt is a marketplace for alternative assets that enables collectors to buy, sell, vault, and finance trading cards. The Lead Engineer, Growth will serve as the founding Growth Engineer, owning the submission funnel, acquisition channels, attribution and analytics foundation, lifecycle infrastructure, and marketplace balance while using AI to improve experimentation and growth operations.
Responsibilities
- The activation funnel. 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. Today a drop-off is an anecdote. It should be a number with a name on it
- Acquisition channels that actually acquire. 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. That includes agentic optimization: how Alt ranks and shows up in ChatGPT, Claude, Gemini, and other assistants. That surface is new for everyone. It's yours
- The data and attribution foundation. This is the unlock for everything else. Stand up clean attribution, consolidate our product analytics into a single source of truth, and modernize the messaging and deep-linking stack so we can finally tell what moved the needle. Until this is right, every other result is contestable
- Lifecycle infrastructure. Turn push, in-app, email, and SMS into an owned, instrumented system rather than per-campaign setups — including SMS opt-in compliance, which is not optional and not glamorous
- Marketplace balance. Watch the balance across bidders, buyers, and sellers, and build growth into whichever side is weak. A marketplace that grows one side only doesn't grow
- Own agentic search visibility as an engineering problem: 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 rather than a guess
- 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, so experiment velocity stops being bottlenecked on copy
- 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
- Use Claude Code or Cursor as the default way you rebuild the funnel instrumentation or migrate the analytics stack, not as autocomplete
Skills
- 5+ years of engineering experience with strong backend (Python, Postgres, AWS or similar) and frontend (React, React Native, JavaScript/TypeScript) chops. This seat is genuinely both
- A track record of owning growth systems or product features from design to production. Design doc to shipped, not a ticket you closed
- 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. Most of the first six months is this
- Comfort owning a north-star metric. You've held a number publicly, weekly, and you know what it feels like when it doesn't move
- Strong collaboration and communication. You write great docs, ask smart questions, and give thoughtful feedback
- If you've built agents, wired up connectors, written skills or MCP servers, or shipped internal tooling your team actually depends on — lead with that. Name the artifact, not the tool
- Bonus: familiarity with the collectibles space or alternative asset marketplaces. You collect, or you have a view on where this market is going
