About the Role
We’re looking for an experienced engineer to help build and iterate on our internal abuse detection tools. As a peer-to-peer marketplace, we’re exposed to a wide array of types of fraud. These include collusion and merchant fraud, phishing, spam, scams, scanners & scrapers, click fraud, account takeover, bot activity, and marketplace abuse. We also work closely with the Trust & Safety, Policy, Legal and ML teams to build tools for compliance and repeat infringement detection.
On the Platform Protection team you’ll be on the front lines of attacks, and your work will require you to stay on your toes, think creatively, and be ready to respond to an ever-evolving threat. You have to have a deep curiosity about the miscreants, and a willingness to explore any means necessary to defend Etsy and its members.
More specifically, we’d like you to have SQL experience and understand how to isolate the problem to minimize false positives, do the necessary data investigation into the issue, propose a range of solutions, then execute on the best possible solution given our infrastructure, time frame, and dependencies. We rely directly on data, alerts, and metrics to drive our models and prevention strategies. We're looking for a new engineer to join the team and bring an expertise in abuse detection through real time detection systems and machine learning.

  • Deploy code in your first week on the job

  • Understand current, new, and unexpected threats and attacks, and develop creative approaches to mitigating these

  • ABI: always be iterating on our existing fraud and abuse detection models

  • Genuinely care about the health and well-being of Etsy and our members, strive to protect their business from abuse with creative detection and prevention solutions

  • Create and ship new tools that enable Etsy to maintain its reputation as a safe and trusted marketplace

  • Identify and communicate best practices for risk detection development

  • Support and empower your colleagues around the company to seek input on new features and product launches

  • Have experience in threat modeling and incident response

  • Are familiar with Etsy, ecommerce, and online fraud
