Arena Club is seeking a Fraud Analyst to serve as the founding member of their risk team. This is a ground-floor opportunity to build fraud prevention strategies and rules-based systems from scratch, protecting the business infrastructure, payment ecosystem, and platform against financial scams and payment abuse.
Key responsibilities include designing and implementing the company's initial rules-based fraud detection system; monitoring transactional data, user registrations, and payment flows to identify sophisticated merchant-facing fraud; leveraging AI tools and LLMs to analyze complex data patterns and automate workflows; querying transactional databases to uncover systemic anomalies and translate trends into actionable fraud prevention policies; managing the end-to-end chargeback dispute process to optimize evidence submission and recovery; and partnering with the Director of Customer Service to integrate risk assessment workflows into customer support while minimizing friction for legitimate users.
Required qualifications include a bachelor's degree in a quantitative discipline and 1–3 years of experience in fraud operations, trust & safety, payments risk, or chargeback/dispute operations. The ideal candidate is highly tech-forward with demonstrated experience using AI platforms (e.g., Claude) to analyze information and scale output; proficient in SQL for independent database queries and advanced Excel for transactional analysis; autonomous and comfortable navigating ambiguity; and possesses a strong foundational understanding of digital payment networks, merchant-side credit card processing, and chargeback mechanics. Experience with large payment processors such as Stripe is required. Metabase experience is preferred.
