As a member of the team, you’ll build new user-facing experiences, scale internal infrastructure, and design intelligent automation to help us solve thousands of customer issues per hour.

You’ll lead solutions end to end. You’ll translate ambiguous business problems into clear technical solutions and drive delivery and experimentation. Your role will involve creative problem-solving to balance development speed, product impact, and technical excellence.

Team members in this role are required to be within commuting distance of our San Francisco, Seattle, Los Angeles, or New York hubs.

  • Bachelor’s degree in Computer Science, a related field, or equivalent work experience.

  • Ownership Mindset: Own projects holistically from inception to production and beyond. You are known for shipping high-quality products and features lightning-fast.

  • Product Instinct: Excel at translating user needs to effective technical solutions.

  • Problem Solving: Thrive in ambiguity and tackle challenging problems with creativity and autonomy.

  • Team Leadership: Proactively improve the team environment and foster inclusive, supportive team culture.

  • Monthly allowance to dogfood the app

    • All Whatnauts are expected to develop a deep understanding of our product. We're passionate about building the best user experience, and all employees are expected to use Whatnot as both a buyer and a seller as part of their job (our dogfooding budget makes this fun and easy!).

  • Parental Leave

    • 16 weeks of paid parental leave + one month gradual return to work *company leave allowances run concurrently with country leave requirements which take precedence.
