Head of Marketplace

What You’ll Do

• Work directly with the CEO and Head of Product to design, build, and optimize Matium’s digital marketing funnel end-to-end.
• Own the first-time buyer and seller experience—from initial awareness through account activation and first transaction.
• Deeply understand Matium’s target market and customer personas across the commodity plastics supply chain.
• Leverage AI tools and modern marketing technology to iterate rapidly, test hypotheses, and scale what works.
• Report on KPIs up the funnel: website conversion, new buyers and sellers, time-to-first-win, and ROMI.
• Collaborate with a mission-driven team to drive new buyers and new sellers onto the platform consistently.

Who You Are

• Experience building and scaling digital marketing funnels for a marketplace, SaaS, or B2B platform.
• Experience in mapping user journeys and designing UX workflows for B2B users – bonus if experienced in sales/procurement activities.
• Strong analytical instincts—you think in terms of conversion rates, cohort analysis, and cost per acquisition.
• Hands-on experience with AI-assisted content creation, marketing automation, and growth experimentation.
• Ability to deeply understand a niche market and craft messaging that resonates with technical buyers and sellers.
• Comfort with ambiguity and the pace of an early-stage company. You build the playbook, not follow one.
• Excellent collaboration skills—you’ll work closely with Product, Technology, and Markets teams daily.
