Job Description
This Senior Software Engineer II post sits in the Account Integrity team, part of the Fraud Squad at Wise in London. The team stands on the front line against financial crime. It draws on machine learning, live transaction monitoring and sophisticated data analysis to build controls, aiming for a fraud prevention engine that can scale globally and safeguards accounts and stops scams before they succeed.
The engineer takes full charge, from start to finish, of projects that build and refine controls against account takeover attacks on Wise customers. The effect is measurable: stronger protection of customer security, plus faster product growth through greater automation. The work is roughly 80 percent backend and 20 percent frontend, spanning the crime prevention and detection systems.
The position calls for a strong product mindset, the drive to run projects independently, and decisions grounded in data with customers in mind. The engineer works with product, data science and investigations colleagues and must explain technical ideas clearly to all of them.
The post is full-time and on-site in London. The listing gives no salary, and it does not spell out how to apply.
Responsibilities
- Build and refine controls that protect customer accounts from takeover
- Drive backend and frontend work for crime prevention and detection systems, roughly 80 percent backend and 20 percent frontend
- Carry projects from first design to launch, driving them forward on your own
- Raise automation levels to support product growth and protect customers' money
Requirements
- Professional experience with Java or another JVM language, including the Spring framework
- Track record of designing and running CI/CD pipelines as well as distributed, concurrent systems
- Working knowledge of SQL and NoSQL stores, with skill in tuning queries and building durable schemas
- Strong product mindset, accountability and data-driven decision making
- Dedication to test-first development and strong coding craft
- Ability to explain complex technical ideas to product, data science and investigations teams
Qualifications
- Bonus if you know how ML models move through their lifecycle: pipelines, feature building and getting models live
