Whatnot is the largest live shopping platform in North America and Europe, enabling people to buy, sell, and discover a wide range of items through live, interactive experiences. This remote-friendly role sits within a co-located team anchored by hubs across the US, including New York and Seattle. The Safety XP team builds the backbone that decides what can be sold, to whom, and what happens when something goes wrong, across real-time auctions, transactions, and video.

What you'll do: - Design and develop systems to protect the platform: build and iterate production algorithms and infrastructures that mitigate systemic risks and safeguard buyers, sellers, and the broader Whatnot community. - Balance risk and user experience: proactively monitor the impact of protective systems on trusted users, ensuring interventions deliver more value than friction. - Respond in real time to threats: architect event-driven pipelines and detection frameworks that enable near real-time responses to high-risk user behavior. - Contribute across the full development lifecycle: engage in ideation, scoping, prototyping, load testing, deployment, and monitoring to deliver resilient and scalable solutions. - Drive cross-team initiatives: collaborate across multiple product surfaces and operational teams, surfacing insights to leadership and stakeholders through dashboards, notebooks, and clear written documentation. - Continuously evolve defenses: stay ahead of emerging abuse patterns, abuse vectors, and account integrity risks by iterating quickly and rigorously testing solutions.
