Software Engineer, Ads

About the role

Ads is a growing engineering team at Whatnot dedicated to building systems & features to help Sellers grow their business. As a software engineer on the Ads team, you'll make sound product decisions, navigate new domains seamlessly, take extreme ownership, and ship high-quality products fast. We prioritize the highest-impact features and ship them quickly, giving engineers significant individual responsibility and freedom. Your ability to put customers first, make good trade-offs, and deliver impact is essential.

We're hiring across the full ads stack — from engineers who go deep on backend systems and data to engineers who move fluidly across the stack into client and seller-facing surfaces. You'll own problems end-to-end and grow into new areas as the team scales.

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.
• Understand our buyer and seller experiences and become an expert in helping them effectively scale their business through ads products.
