About the role

Ads-focused role within Whatnot's engineering team, building scalable backend and full-stack ads systems to help Sellers grow their business across bidding, targeting, ranking, serving, and campaign tooling.

Responsibilities

  • Build ads products by working across the full ads stack including bidding & targeting, ranking/auction, serving, campaign management, and seller tooling.
  • Build highly scalable ads systems that handle all aspects of running an online advertising system and help sellers differentiate themselves on Whatnot.
  • Dig deep into data, logging, and system behavior to reason about performance, correctness, and impact — not just ship features, but understand why they work.

  • 4+ years of professional software engineering experience building and shipping backend systems in production environments.
  • Strong experience designing, building, and operating scalable, maintainable backend services.
  • Strong technical judgment and the ability to make thoughtful tradeoffs between speed, quality, reliability, and long-term maintainability.
  • Experience working in fast-moving, cross-functional product or platform environments.
  • Comfort owning ambiguous problem spaces and turning them into clear technical plans and shipped outcomes.
  • Strong communication and collaboration skills, especially when partnering across engineering, product, design, and data.
  • A product-minded approach to engineering — you care not just about whether a system works, but whether it creates value for users and partner teams.
