Senior Graph ML Scientist: Entity Resolution & Fraud

TWG Global AI; Santa Monica (CA); On-site; USD 190,000 - 290,000; Full time

Job summary

TWG Global AI is seeking an experienced Graph ML and entity-resolution expert for an onsite Santa Monica/NYC role. You will own the entity graph, develop stable clustering, and detect coordinated behavior across accounts, wallets, and on-chain data.

Production ML and fraud/AML domain experience are highly valued as you collaborate with engineering to scale data sources and markets. The role focuses on building robust graph pipelines, applying embeddings, and delivering real-time, data-driven

Qualifications

• Experience with graph ML, embeddings, or GNNs on large-scale graphs.
• Entity resolution/record linkage at scale.
• Community and cluster detection, embedding-based or classical approaches.
• Track record detecting coordinated or collusive behavior—fraud, AML, or coordinated campaigns.
• Production ML experience: building graph pipelines that run in production.
• Financial-crime, market-surveillance, or trading-domain exposure is a plus.
• DeFi on-chain wallet clustering experience is strongly preferred.

Responsibilities

• Build and maintain the entity graph linking accounts, counterparties, wallets, and behavior into a single picture of who is really acting.
• Develop entity-resolution and clustering methods that stay stable over time, so the same actor is recognized as they resurface.
• Detect coordinated behavior and collusion rings, including cases with no explicit shared identity; DeFi wallet-farming and sybil detection via entity resolution.
• Co-own the Attribution Substrate: fusing vendor attribution clusters with on-chain behavioral clustering into a confidence-scored layer.
• Build graph-based features and representations (embeddings, network features) for the broader detection system.
• Partner with engineering as the graph extends to new data sources and market types.
