Our real-time marketplace enables licensed dealerships to compete for vehicles directly from individual sellers, creating a faster, more transparent and more efficient automotive marketplace. We recently raised a $15M Series A backed by leading Silicon Valley investors. Over the past year, our business grew 7x through California operations alone, reaching approximately $300M in annualized GMV, and we are now accelerating expansion across multiple U.S. markets. ABOUT THE ROLE We are hiring a Senior Product Manager to lead Marketplace Growth & Liquidity.

MINIMUM QUALIFICATIONS - 5+ years of Product Management experience. - Required: Experience building or scaling a two-sided marketplace. - Strong understanding of marketplace liquidity, supply-and-demand dynamics and network effects. - Experience owning marketplace, growth or transaction metrics. - Experience taking products from strategy and discovery through launch and iteration. - Strong analytical skills and comfort working with marketplace, cohort and behavioral data. - Strong product judgment and systems thinking. - High ownership and the ability to operate effectively in a fast-moving startup environment. - Excellent communication and cross-functional leadership skills. PREFERRED QUALIFICATIONS - Experience building marketplace matching, ranking, recommendation, pricing or notification systems. - Experience with dealer, B2B, B2B2C or transaction-platform products. - Automotive, logistics, commerce, mobility or auction marketplace experience. - Experience launching products from 0→1 and scaling them across multiple markets. - Previous startup or high-growth company experience. WHY BIDBUS - Own one of the company’s most strategically important product areas. - Work directly with the founders on company and marketplace strategy. - Build the systems behind Bidbus’s national expansion. - Launch ambitious 0→1 product bets with direct business impact. - Competitive compensation, meaningful equity and benefits. - Help shape one of the fastest-growing automotive marketplaces in the U.S.
