Backend Engineer - Feature Platform

The team you will be joining: Feature Platform

Wise moves billions every year for millions of people and businesses across many different countries and currencies, while bad actors constantly evolve: scams, impersonation, account takeover, money laundering, mule networks, and other forms of abuse emerge. At this scale, in order to stay ahead of evolving threats, our automated controls and machine learning models require high-quality, real-time insights.

Wise's centralized feature engineering platform for financial crime detection is the Feature Platform. Its goal is that every fraud signal, AML indicator, and risk feature flows through a single governed platform instead of each team maintaining siloed calculations. It owns the feature lifecycle from finding, experimenting, and building data points to using them in millions of transactions daily.

How can you contribute?

• Engineering: tackle complex technical challenges focused on scalability, reliability, and speed, maintaining a high-performance infrastructure that processes millions of events with low latency.
• Innovation: collaborate with Data Scientists and Engineers to design and implement cutting-edge feature topologies, including graphs, support vectors, and time-series data.
• Engagement: drive platform adoption by partnering with teams across Wise to centralize existing risk logic and expand our self-service capabilities.

What does it take?

• 3+ years of Java 11+ knowledge, fluent in Java 21+
• Familiarity with Python (or willingness to learn on the job)
• Experience with batch or stream processing (preferably Apache Spark and Flink/Kafka streams)
• Familiarity with SQL and no-SQL (document) databases
• Experience with complex systems distributed across several microservices, Kafka, scattered data and ownership
• Hands-on knowledge of system integration patterns
• A strong product mindset and passion for user experience
• Strong problem-solving skills to help refine problem statements and figure out how to solve them from first principles
