Lead Engineer, Growth
About The Position
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. You are our founding Growth Engineer, and you turn today's experiments into instrumented, repeatable systems across both sides of the marketplace — sellers and buyers. Attribution that we trust. A submission funnel we can measure step by step. Lifecycle messaging that is an owned system rather than a stack of per-campaign setups. Channels we can scale on purpose instead of by accident. The metric you own: unique submissions. It is our north star, the whole company watches it, and you'll be held to it with the same weekly-reported discipline we hold marketing to. It's a technical owner who understands growth levers and can build them — thinks like a PM, builds like an engineer. You'll partner directly with our founder and our Head of Marketing, own the funnel end to end, and the ceiling here is running the growth function. The people who are great at this have stepped back from a backlog before, instrumented a funnel nobody had instrumented, found the real blocker, and gone after it without being asked.
Requirements
- 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.
Nice To Haves
- Bonus: familiarity with the collectibles space or alternative asset marketplaces. You collect, or you have a view on where this market is going.
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.
Benefits
- We cover 85% of your medical, dental, and vision, and up to 50% for dependents. HSA/FSA available
- Flexible PTO that people actually take
- Parental leave at full salary
- $200/month wellness + $100/month home office stipend
- Free DoorDash membership, because dinner shouldn't be a decision
- Remote-first (for most positions), with WeWork access when you want a room with other humans
- 401(k)
- Alt Equity to all full-time employees
