Write the memos and responses partners and auditors rely on Draft incident and retro memos for bank partners and internal risk governance: what happened, impact, root cause, controls in place, remediation plan, and timelines. Use AI tools to get from raw incident data to a strong first draft quickly, then verify every number and claim against source data before it leaves the team. Prepare accurate, concise responses to partner-bank questions, suspicious activity and investigation inquiries, and requests for information. Coordinate with bank partners Be a day-to-day operational point of contact for partner-bank risk, AML, and investigations teams, working alongside Partnerships and Compliance. Track open partner requests, commitments, and change-management items, and make sure Fraud Operations responds consistently and on time. Bring partner feedback and expectations back to Fraud Operations, Strategy, and Product so controls and processes are built with the partner in mind.

Keep evidence, SOPs, and decision records current so that an audit or exam never becomes a scramble. Track issues through governance systems in partnership with Enablement until closure, and confirm the fix worked. Raise the bar for the team Mentor teammates on how to elevate: bring a recommendation and the facts, not just a question.

Working knowledge of how a regulated institution runs, with direct experience working with sponsor or partner banks, regulators, examiners, or auditors. Solid understanding of US payment rails and fraud typologies, such as ACH, wires, checks, cards, account takeover, mule accounts, and synthetic or first-party fraud. Comfort with data: you can pull and interpret volume, loss, and rate data (SQL or dashboard tools), and explain what the numbers mean and where they could mislead. Proven ability to influence people who don't report to you and to drive decisions to closure across Operations, Strategy, Product, Engineering, Compliance, and Legal. Good judgment on escalation: you bring a recommendation with the facts and make the next decision easier for leaders. Experience using AI and automation to synthesize evidence, draft documents, summarize incidents, and keep status reporting current.
