[Hiring] Product Builder @Alt Platform Inc

Role Description

Alt is growing! This role leads the charge on new user count: how many collectors land on Alt, how many make a first submission or a first bid, and how many come back without being asked. That number is the job. Everything else in this description is downstream of it.

This is a builder seat, not a product management seat. You own the seller submission funnel, buyer search and discovery, and the experimentation infrastructure underneath both, and you own them the whole way:

• Find the drop-off
• Write the code
• Ship it behind a flag
• Read the result
• Keep it or kill it

What this role is not:

• Writing PRDs for someone else to implement
• Running roadmap ritual
• Managing a pod
• Translating between engineering and the business

What it is:

• Pulling the funnel yourself in SQL on Monday
• Shipping the onboarding change on Tuesday
• Standing up the experiment harness that makes Wednesday's test trustworthy
• Putting a model behind dealer reactivation instead of a campaign

You report directly to the CEO. If you want a CEO in the build with you, this is that. If you want distance from the top, it isn't.

The metrics you own:

• Submission Volume (weekly, by seller segment)
• Search-to-Bid Conversion

Supporting KPIs:

• Snap to Sell activation rate on first submission
• Seller reactivation rate among dormant sellers
• Daily active search query volume
• Listing rate (vaulted inventory live on marketplace)
• Ship-and-decide velocity (changes shipped and tests called per week)
• Dealer segment submission frequency and GMV

The people who are great at this have run growth inside a system that was already working, not just inside a roadmap someone else set. They ship their own code. And they are participants in this market: they buy, they sell, and they have a view on where liquidity actually goes.

Qualifications

• You ship production code.
• You've owned a growth surface, marketplace funnel, or PLG motion and moved the number on it.
• You own a number today and can name it, its baseline, and where you took it, on the first ask.
• Strong data fluency: SQL and Python, plus PostHog, Amplitude, Mixpanel, Statsig, Eppo, or similar.
• Experimentation in your hands, not on your résumé.
• Deep understanding of two-sided marketplace dynamics.
• You've built real things with AI, not just used it.
• Scrappy and high-ownership.

Requirements

• You've designed the test, set the decision rule before it ran, and made the call on partial data.
• Communicate with precision, move without hand-holding, and go find the problem rather than waiting for the brief.

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.
