Wise is one of the fastest-growing global financial platforms, and as we scale, so does the sophistication of the ML systems protecting every transaction. Our Risk ML team is building the model lifecycle platform that makes it possible to develop, deploy, and monitor ML models for financial crime detection - reliably, reproducibly, and at scale.We're looking for a Senior ML Platform Engineer to build this platform from the ground up. You'll design the infrastructure that turns model development from a bespoke, manual process into a scalable, standardised one - so our data and applied scientists can focus on improving detection rather than managing operations.This is a greenfield build with strong investment and direct engagement from Wise's senior leadership.
Risk ML sits within Wise’s FinCrime organisation, owning the full ML and AI foundation for financial crime detection. We're scaling into three dedicated pillars - Feature Platform, Learning Loop, and Risk Modelling. You'll sit in Risk Modelling, building the platform layer that makes scaling our detection capabilities possible.You’ll work closely with data scientists, feature platform engineers (upstream infrastructure), and Wise's central ML platform team (shared foundations). We value engineers who build for adoption - internal platforms succeed when teams want to use them.What will you be working on?
Designing and building the declarative training pipeline - standardised, config-driven model training that any data scientist can use without writing deployment codeBuilding model packaging and serving abstraction - a unified interface that handles multiple model types (classical ML, deep learning, emerging architectures) through a consistent APIImplementing the model evaluation framework - standardised metrics, reproducible comparison, and automated validation gatesBuilding model monitoring - drift detection, performance degradation alerts, automated retraining triggers, and full audit trails for regulatory complianceOwning the integration layer with Wise's central ML infrastructure - aligning on boundaries so FinCrime-specific lifecycle tooling builds cleanly on shared foundationsMaximising data science productivity - your platform's success is measured by how much time shifts from operational maintenance to improving detection performanceStarting salary: £87,500 - £111,000 + RSUsWise BenefitsAdditional Information
