About the Role: Head of Product As Head of Product at SELLIT9, you'll define what we build, why, and when. You'll own the product roadmap end to end, from the consumer trade-in experience to merchant integrations and internal tools, working directly with the CEO and CTO to turn business strategy into shipped product.
This is a hands-on, player-coach role. We don't have layers of PMs: you are the product function. You'll talk to customers, write specs, prioritize ruthlessly, and ship alongside a small engineering and design team.
A note on AI-native, because it cuts both ways: building with agents daily is non-negotiable here, but AI multiplies judgment, it doesn't replace it. You own every call an agent helps you reach.
What You'll Do Own the product roadmap and prioritization across consumer, merchant, and internal platforms.
Define product strategy aligned with business goals: US growth, new merchant integrations, conversion.
Write clear specs and work directly with engineering and design to ship.
Talk to customers (sellers and merchant partners) regularly to understand pain points and opportunities.
Define and track product KPIs: conversion rate, order completion, partner adoption, NPS.
Use data to find opportunities and validate decisions, in GA4, Microsoft Clarity, BigQuery, and our internal Mercury reports.




Vibe-code your own prototypes with coding agents (Claude Code, Codex, or similar) so ideas reach engineering as working software, not slide decks.
Turn your repeatable product work into agent skills: research digests, spec templates, KPI reports, ticket triage.
Balance new features, tech debt, and operational improvements.
Contribute to go-to-market for new products and partnerships.
Apply if you Have 7+ years of product management experience, including at least 2 leading product at an early-stage startup.
Have shipped products in e-commerce, fintech, or marketplaces.
Are a strong writer: you turn ambiguous problems into explicit specs.
Are deeply analytical and comfortable pulling your own data and running your own queries.
Have worked on both consumer (B2C) and merchant/partner (B2B) products.
Understand technical trade-offs and collaborate well with engineers without being one.
Work AI-natively, and this is non-negotiable: you're comfortable vibe coding a prototype, you generate your own agent skills, and AI agents are part of how you research, spec, and analyze every day.
Are fluent in English (written and spoken).
Even better if you have Experience in trade-in, recommerce, or logistics platforms.
A track record of owning a metric end to end, not just shipping features.
