Megan RImarcuk

I am a payments and fraud operations leader with 9+ years managing high-volume fraud and payment workflows, scaling teams, and partnering cross-functionally to reduce financial risk. I have directed multiple teams and acted as the primary contact for Stripe while collaborating with Legal and Compliance to implement policy and controls.

At Carvana I led fraud, risk, and refund operations across ACH, wire, card, and check, driving initiatives that prevented historically over $370M in losses, reduced post-purchase fraud by over 50%, and achieved a 187% increase in fraud prevented. I built and scaled high-performing teams, recovered and prevented over $80M in losses through targeted fraud strategies, and served as an expert witness in corporate legal proceedings.

I am a hands-on operator who uses data analytics and strategic planning to streamline treasury and payment processes, improve productivity, and minimize operational vulnerabilities. I value collaboration with law enforcement, corporate insurance, and internal stakeholders to create robust trust-and-safety protocols and practical SOPs that protect customers and company assets.
