Your Mission With the power of AI, we're set to revolutionize the way subcontractors find, evaluate, and bid on projects. As the second PM on the subcontractor side, 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 take full product ownership of core areas of the subcontractor product and drive the evolution of the marketplace experience. You identify AI use cases within the subcontractor workflow — e.g., intelligent tender recommendations or automated bidding support — and bring them to life together with our designers and engineers. You analyze user behavior, market trends, and product metrics to spot growth opportunities and translate them into strategic initiatives. You develop hypotheses, validate them through prototypes and experiments, and scale successful approaches together with Design and Engineering. Together with Marketing and Customer Success, you ensure a strong go-to-market for new features. What You Bring 3–5 years of experience in product management in a B2B SaaS environment or a marketplace/platform business model. A solid understanding of marketplace dynamics and the ability to balance supply and demand sides. Strong analytical skills and a talent for turning complex problems into pragmatic solutions. You confidently use AI tools such as LLM-based assistants, MCPs, and no-code prototyping in your daily work. Experience with product roadmaps, user stories, and the full product lifecycle. Fluency in German and English, both written and spoken. Your Benefits Help shape a product that solves real-world problems in the construction industry through AI and is revolutionizing the market.
