Senior Product Manager - Marketplace

Your Mission

With the power of AI, we're set to revolutionize the way general contractors and subcontractors find and match with each other on our marketplace. As our Senior Product Manager Marketplace, you'll actively shape this product vision — in a small team with big leverage and direct impact on a product used by thousands.

Your Responsibilities

• You own the marketplace dynamics between General contractors and Subcontractors on our platform.
• You ensure a healthy balance between supply and demand, and build mechanisms that keep liquidity strong on both sides.
• You own search, matching and recommendation mechanisms that bring Subcontractors and projects together in a way that increases relevance and bid rate.
• You analyze marketplace metrics and translate them into hypotheses and priorities.
• You identify AI use cases for matching and recommendations and implement them together with our designers and engineers.

What You Bring

• 3–5 years of product management experience with two- or multi-sided marketplaces.
• Demonstrated experience thinking through supply-demand dynamics: how to create enough supply, enough demand, and how to balance the sometimes conflicting interests of both sides.
• Experience with search or matching algorithms, or working closely with data and engineering teams on ranking or recommendation logic.
• Strong analytical skills and a solid understanding of marketplace metrics such as liquidity, conversion, and network effects.
• You use AI tools such as LLM-based assistants, MCPs, and no-code prototyping routinely in your day-to-day work.
• Fluent in written and spoken German and English.

Your Benefits

• Help shape a product that solves real-world problems in the construction industry through AI and is revolutionizing the market.
• Work in an open-minded, dynamic, and international team.
• Remote or from our modern office in Berlin Friedrichshain.
• Regular company and team events (offline and online).
• Permanent contract and modern equipment.
• Open feedback culture with regular 1:1s and development conversations.
