Do you thrive on investigation, pattern recognition, and protecting both customers and the business from financial loss? We are looking for a meticulous and analytically driven Chargebacks Analyst to join our Payment Operations team. In this role, you will own the full chargeback and dispute lifecycle — from initial retrieval requests through representation— working directly with card networks, acquiring banks, and internal stakeholders to recover revenue and minimize losses. Beyond dispute resolution, you will play a key role in identifying fraud trends, strengthening our prevention posture, and building scalable processes that protect the integrity of our payments ecosystem. This is an entry-level position with significant growth potential for candidates who combine curiosity with operational rigor.

KEY RESPONSIBILITIES

Dispute & Chargeback Management

• Own the end-to-end chargeback lifecycle across all card networks (Visa, Mastercard, Amex, Discover & PayPal) including retrieval requests, first chargebacks and second chargebacks.
• Prepare and submit timely, evidence-backed representment packages to maximize win rates and recover revenue on behalf of the business.
• Respond to retrieval requests and fulfillment inquiries within network-mandated timeframes to prevent automatic losses.
• Triage incoming disputes by reason code, dispute stage, and financial exposure to prioritize caseload effectively.
• Track and manage all open cases within the platform, ensuring no case ages past its response deadline.
• Analyze dispute outcomes to identify patterns in win/loss rates and refine representment strategies accordingly.

Fraud Investigation & Loss Prevention

• Investigate True Fraud, first-party misuse, and policy abuse patterns surfaced through chargeback filings and user behavior signals.
• Collaborate with the Risk and Trust & Safety teams to take enforcement actions on confirmed fraudulent accounts including blocks, account restrictions, and fund holds.
• Flag high-frequency or high-value dispute clusters to leadership as potential coordinated fraud or network-level compromise events.
• Support pre-emptive refund decisions where accepting a dispute is more cost-effective than representment, balancing recovery goals with operational efficiency.
• Maintain detailed case notes and fraud intelligence logs to support pattern analysis and future investigations.

Process Improvement & Cross-Functional Collaboration

• Contribute to the development and maintenance of chargeback SOPs, decision trees, and representment templates.
• Partner with Engineering to surface friction points in the buyer and seller experience that contribute to dispute volumes.
• Provide operational input during payment processor or chargeback tool evaluations and onboarding.
• Collaborate with Customers to resolve escalated user-facing dispute queries and communicate expected resolution timelines.
• Proactively share chargeback trend intelligence with Fraud & Risk and Leadership to inform strategic decisions.

• Build proficiency with the chargeback management platform and back-office tools to execute account and order-level actions.
• Meet or exceed defined SLA targets for response timeliness, representment submission, and case closure rates.
• Proactively surface identified fraud patterns, dispute trends, and risks to the broader team.

Within 12+ Months

• Exceed all 6-month benchmarks and responsibilities.
