• Deep understanding of common fraud typologies (refund abuse, payment fraud, chargebacks, promo abuse).
• Advanced proficiency in SQL (BigQuery experience a plus) and strong database acumen, including GitHub.
• Advanced data visualization skills using tools like Looker and Tableau.
• Strong communication ability to translate complex data into clear, compelling narratives for all audiences.
• Comfortable presenting findings to influence senior and non-technical decision-makers.
• Agile Mindset: Familiarity with Agile methodologies; practical experience with Jira and working within a sprint environment.
• Sharp analytical mind with a passion for complex problem-solving and a keen eye for detail.
