About the Role
As we scale, we're making our first dedicated chargeback & fraud hire, a hands-on practitioner who will build our fraud function from the ground up: fraud tooling, investigations workflow, alert triage, and bank-partner reporting.
This role reports to our Risk Manager within the broader Risk & Compliance organization, and requires 5–8 years of relevant experience.
This is a builder role, not a maintainer role. You'll be the fraud subject-matter expert inside Coinflow, working alongside our BSA/AML Officer, Underwriters and Data Science, and will be the primary point of contact for fraud-related RFIs from our sponsor bank partners.
What You'll Do
Build the fraud function
- Further develop and mature our existing transaction monitoring tool and investigations workflow, including case management, alerting logic, and evidence documentation standards.
- Define SOPs, escalation paths, and decision frameworks for fraud investigations as the team's first dedicated hire.
Work alerts, investigations, and remediation
Monitor and triage fraud alerts across merchant and user/cardholder populations, investigating transaction patterns, account activity, and behavioral signals.
Conduct deep-dive investigations into suspected fraudulent merchants, card testing, account takeover, ACH fraud, and related fraud typologies.
Drive remediation: case disposition, funding actions, merchant/user offboarding recommendations, and root-cause analysis on confirmed fraud losses.
Identify and manage fraud risk vectors
- Continuously assess Coinflow's exposure across merchant fraud (fraudulent merchant onboarding, bust-out schemes, transaction laundering) and user fraud (ATO, card testing, CNP fraud, ACH fraud, scams).
- Track chargeback and fraud trends specific to our high-risk verticals (crypto on/off-ramps, gaming, remittance, digital goods) and recommend controls.
- Monitor card network programs (VAMP, ECM/HECM, EFM, VIRP, BRAM, and new programs as they launch), in addition to NACHA program requirements, manage merchant remediation to stay below thresholds, and build workflows to meet new program requirements.
- Track industry developments, network rule changes, and regulatory updates, and translate them into product and control recommendations.
Bank partner & stakeholder engagement
Serve as the primary owner of fraud-related RFIs from sponsor bank partners, preparing data, narratives, and supporting documentation.
Partner with the BSA/AML Officer and Data Science to align fraud and AML signal-sharing and investigations.
Present fraud metrics, trends, and program updates to Risk & Compliance leadership.
Operational Leadership (as the team grows)
Hire, train, and mentor fraud analysts.
Build out queue SLAs, escalation paths, and QA/calibration of analyst decisions.
Own the fraud playbooks and procedures.
Requirements
- 5–8 years of experience in chargeback & fraud prevention, detection, investigations, or remediation within a payment service provider, Acquirer, or fintech platform.
- Strong, hands-on understanding of fraud in the card acquiring space, covering both:
- Merchant fraud: Fraudulent merchant onboarding/boarding fraud, transaction laundering, bust-out schemes, collusive merchant activity.
- User/cardholder fraud: Account takeover (ATO), card testing, card-not-present (CNP) fraud, scams and social engineering.
- Working knowledge of card brand fraud and chargeback monitoring programs such as VAMP, ECM, SMMP, VIRP, BRAM, etc., and experience remediating merchants against these thresholds.
- Experience building or significantly improving fraud tooling, case management workflows, or investigations processes. This is a builder, not just an operator.
- Comfortable responding directly to bank partner and sponsor bank RFIs, including preparing data and written narratives.
- Highly analytical; comfortable using data to identify emerging fraud trends and to justify policy or tooling changes.
- Excellent written and verbal communication skills. Able to explain complex fraud findings clearly to non-fraud stakeholders and external partners.
- Sound judgment and ability to make and stand behind difficult, sometimes ambiguous, fraud decisions.
Preferred Qualifications
Experience with high-risk or emerging verticals such as crypto on/off-ramps, gaming, sweepstakes, digital goods.
SQL proficiency or comparable data skills to build dashboards, track fraud metrics, and drive investigations independently.
Familiarity with AML/KYC/underwriting processes and how fraud and onboarding signals intersect in a payments risk organization.
People leadership experience or a demonstrated path toward building and leading a fraud team over time.
Comfortable discussing complex merchant processing situations with Acquirers, Sponsor Banks, and the Card Networks.
Join the team rewriting how money moves worldwide—and become a driving force in the $194 trillion cross-border payments market.
