Senior Fraud Investigator at Etsy in New York, NY

Job description

Company Description Etsy is the global marketplace for unique and creative goods. We build, power, and evolve the tools and technologies that connect millions of entrepreneurs with millions of buyers around the world. As an Etsy employee, you will tackle unique, meaningful, and large-scale problems alongside passionate coworkers, all the while making a rewarding impact and Keeping Commerce Human. We believe exceptional companies are built by exceptional teams, and we're intentional about it. That means hiring great people, setting them up for success from day one, and giving them real reasons to grow their careers here. We invest in development that goes beyond promotions, and we foster the trust and relationships that help people do their best work together. What’s the role? As a Senior Investigator, you are responsible for defining and driving high-impact investigations that strengthen Etsy’s ability to identify, understand, and respond to evolving fraud threats at scale. This role builds on strong investigative foundations, but the scope is broader and more strategic. Rather than only executing within a defined queue or assigned problem space, you’ll help identify the most important risks to the business, shape the investigative approach, and drive cross-functional efforts from problem definition through remediation. You’ll use insights from complex casework, fraud trends, operational signals, and data analysis to connect patterns across multiple fraud surfaces, size impact, and develop evidence-backed recommendations. From there, you’ll translate findings into improvements across fraud controls, tooling, workflows, model strategy, and risk mitigation approaches in partnership with Product, Engineering, Analytics, and other stakeholders. You’ll act as a senior subject matter expert for investigations, leading ambiguous and high-stakes work across teams, communicating complex issues clearly to a range of audiences, and helping align partners around effective solutions. You’ll also serve as a force multiplier by mentoring other investigators, raising the quality bar for investigative work, and introducing stronger frameworks and practices that improve how the broader organization responds to fraud over time. This is a full-time position reporting to the Sr Manager, Operations, Account Integrity & Security. What’s this team like at Etsy? Our Risk & Fraud organization is structured into four areas of focus: Account Integrity and Security, Merchant Risk, Transaction Fraud, and Marketplace Fraud. While we operate as one connected Risk & Fraud team, this role sits within Account Integrity and Security, where we focus on protecting Etsy accounts from compromise and abuse. This team works to prevent account takeovers, enforce platform policies, and safeguard the trust and safety of our marketplace by strengthening identity signals, clustering related accounts, and ensuring the overall integrity of user accounts. What does the day-to-day look like? Lead complex, cross‑vertical investigations: Proactively identify and frame investigations, rather than only working from an assigned queue. Synthesize complex data patterns such as enforcement trends and chargeback spikes into executive-level reports with clear remediation roadmaps for both technical and non-technical stakeholders. Drive end-to-end investigations across diverse domains (fraud, account integrity, content abuse, and security signals) to move beyond siloed specialties. Leverage advanced analytics (SQL, Looker) to define investigation objectives, conduct investigations, size impact, and provide evidence-backed strategic recommendations. Shape models, tooling, and product strategy: Directly influence ML strategy by partnering with Data Science and Engineering on feature engineering, labeling strategies, and experiment design, proposing new features, labeling strategies, evaluation criteria, and experiment designs, not just providing operational feedback after the fact.
