Job Description

The Ads+Promos team at Whatnot is dedicated to building systems & features to help Sellers grow their business. As a Software Engineer, the most important qualities you'll need are making sound product decisions, navigating new domains seamlessly, taking extreme ownership, and shipping high-quality products fast. You will architect, design, and lead the implementation of high-throughput, low-latency distributed systems that power ad delivery, ranking, signal pipelines, and attribution.

You will own core foundational services (e.g., storage, attribution, streaming pipelines, APIs) and drive their evolution, performance tuning, resilience, and scalability. You will also define and enforce architectural patterns, service contracts, fault-isolation, and capacity planning across teams that build on top of the Ads Foundation stack.
