More about our mission.

The team you will join: Fraud Decisioning team

The team is dedicated to safeguarding our platform against financial crime and ensuring the protection of our legitimate customers. Leveraging cutting-edge machine learning, real-time transaction monitoring, and data analysis, our team is responsible for developing and enhancing payment fraud detection systems. Software engineers, data analysts, and data scientists collaborate on a daily basis to continuously improve our systems and provide support to our fraud investigation team.

Our vision is:

• Build a globally scalable payment fraud prevention and detection real-time engine to keep Wise as a secure environment for our legitimate customers.
• Utilise machine learning techniques to identify potential risks associated with customer activity.
• Foster a strong partnership between our fraud investigators and the product team to develop solutions that leverage the expertise of fraud prevention specialists.
• Not only meet the requirements set by regulators and auditors but also surpass their expectations.

What does it take?  

• Demonstrated experience delivering at least 3 full-lifecycle Java/JVM-based projects, each spanning 3-6 months in duration
• Experience with CI/CD pipelines and Distributed and Concurrent Systems
• Hands-on experience with Kafka, Kafka Streams or Apache Flink
• Experience with OLAP databases or data-lakes with Kafka ingestion is a plus
• A strong product mindset and passion for user experience, you prioritise work with the customers in mind and make data-driven decisions to fix customer pain-points
• You believe in and follow best coding practices, code reviews and open feedback
• Being able to work autonomously on customer problems is a key to success - you take responsibility and end-to-end ownership of your projects: drive and own them to make sure we hit the goals we want to achieve
• Close collaboration with product managers, data scientists, data analysts, engineers and other product teams is a must have and is something to expect to happen on a daily basis.
• Great communication skills (both verbal and written) and the ability to articulate complex, technical concepts to non-technical audience
• Hands-on experience working with relational and non-relational databases, query optimisations, designing and evolving schemas
• Experience with machine learning basics (data pipelines, feature engineering, recall/precision, familiarity with machine learning systems in production) is a huge plus
• Being able to propose technical solutions that optimise for latency and throughput at the same time - aka: p99 end-to-end latency is under 1 second for real-time payment fraud checks even when a significant amount of transactions are in the system.
