ABOUT THE ROLE
Fraud at Nelo is moving toward an agent-operated model. AI does most of the volume. Humans set the standard. This role is the operating layer underneath that strategy, and it owns two things end-to-end: the AI fraud investigation stack, and AML.
On the AI side, you are the person who decides what good signal looks like, curates the seed cases that train the agents, writes the instructions that tell them where to look and what to ignore, and designs the JSON schemas they read from and write into. You build the filter that sits between CX intake and the agents so we feed them signal instead of noise. When new fraud MOs emerge, you catch them and feed the agents before performance decays.
On the AML side, you own casework, SAR narratives, escalations, and the operating cadence that keeps Nelo defensible if and when a regulator walks in. This is low-frequency, high-stakes work. It cannot be a side task and we are not treating it as one.
You will work closely with CX (the source of most raw signal), Risk, Legal & Compliance, and Engineering.
