Product Manager, Ads & Promo at whatnot

This role is designed for a heavyweight Product Leader with at least 10 years of experience, specifically within the e-commerce advertising or marketplace promotions domain. The ideal candidate has deep technical fluency in building ad ranking algorithms, bidding engines, and ML-driven auction dynamics. You should be comfortable operating in a high-pressure, "1 to 100" scaling phase where you must balance complex data science with a seamless seller experience. The compensation is highly competitive ($240k - $320k) and comes with a robust benefits package, including a 4% 401k match and unique "dogfooding" budgets to shop on the app. While the company is remote-first, they prioritize "remote co-location," meaning you must live within commuting distance of their hubs in NYC, LA, SF, or Seattle to collaborate effectively with the leadership team. **You might be a good fit if you...** * Have a proven track record of building native advertising tools or seller incentive programs in a marketplace. * Are comfortable designing real-time systems involving streaming data and event-driven triggers. * Excel at translating complex ROI/ROAS metrics into simple, actionable dashboards for small business owners. * Thrive in fast-paced environments where you lead strategy but also "roll up your sleeves" to define technical requirements.
