Senior Software Engineer, Ads & Monetization

Whatnot (YC W20) is a livestream shopping platform and marketplace backed by Andreessen Horowitz, Y Combinator, and CapitalG. We’re one of YC’s top companies and one of the fastest growing marketplaces ever. We’re laser focused on creating an exceptional software company, team, and place to work. You can read our principles here.

Our mission: enable anyone to turn their passion into a business and bring people together through commerce. We’re building the future of ecommerce; an interactive community where creators can make a living off their passion.

Did we mention we’re high growth? In January 2021, Whatnot had 10 ambitious employees. Today, the Whatnot team is 300+ employees and will exceed 350 by year end. We’re hiring forward thinking problem solvers across all functional areas. We recruit thoughtfully, can adapt quickly, and are scaling fully remotely.

The e-commerce experience has been static for 20+ years and is one of the largest opportunities for disruption in the startup space today. Livestream shopping is a $300B GMV market in China and has grown 100% YoY. Retail is a $5T market opportunity!
