• Banks and e-wallets join an industry proof of concept; you translate shared needs into a testable data solution
• A new fraud pattern emerges; you build analysis that helps specialists discover accounts, identities and transactions of interest
• Monitoring relies on manual work; you drive automation that improves the quality and repeatability of risk reporting

##

What Will Help You Succeed

• More than five years of relevant experience in data engineering, data science or both, supported by a related degree
• Strong programming capability in Python and SQL, with working exposure to languages such as C#, VBA or equivalents
• Hands-on experience with big-data technologies such as Hadoop or Spark, cloud platforms such as AWS, Azure or GCP, and container orchestration using Kubernetes
