• Develop efficient queries and Graph Data Science algorithms to support entity resolution, link analysis, and investigative insights. 

• Work with graph visualization tools to build intuitive investigation tools for investigators and analysts. 

• Collaborate with Financial Crime/Fraud analysts to translate investigation use cases into graph-driven solutions. 

• Optimize data performance and ensure data quality across graph structures. 

• Partner with software engineers and data scientists to integrate graph data into wider Financial Crime/Fraud workflows and detection logic. 

Must-Have:

• 3+ years of experience in Data Engineering, Graph Data Modeling, or related fields. 

• Hands-on experience with graph databases (e.g., Neo4j, TigerGraph, JanusGraph, Neptune or similar). 

• Proficiency in Python or PySpark for data manipulation and integration on Databricks. 

• Solid understanding of data modeling, ETL, and query languages (Cypher preferred). 

• Strong analytical mindset and problem-solving skills. 

• Good English communication skills (written and verbal). 

• Ability to work effectively in cross-functional, international teams. 

Nice to Have:

• Experience with  graph visualization tools (Bloom, Linkurious etc) 

• Knowledge of Entity Resolution, Fraud Detection, or AML / KYC systems. 

• Experience integrating graph databases with case management or Financial Crime/Fraud workflows. 

• Familiarity with cloud-based data platforms (AWS). 

• Join a mission-driven product tackling real-world financial crime challenges through data and technology. 

• Work with modern graph technologies and cutting-edge data platforms. 

• Collaborate with global teams across Vietnam, Philippines, Singapore, and South Africa.
