Senior ML Platform Engineer II Financial Crime

About the role:

• 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.
• Were looking for a Senior ML Platform Engineer to build this platform from the ground up. Youll 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 Wises senior leadership.

How we work:

• Risk ML sits within Wises FinCrime organisation owning the full ML and AI foundation for financial crime detection. Were scaling into three dedicated pillars - Feature Platform Learning Loop and Risk Modelling. Youll sit in Risk Modelling building the platform layer that makes scaling our detection capabilities possible.
• Youll work closely with data scientists feature platform engineers (upstream infrastructure) and Wises 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 code
• Building model packaging and serving abstraction - a unified interface that handles multiple model types (classical ML deep learning emerging architectures) through a consistent API
• Implementing the model evaluation framework - standardised metrics reproducible comparison and automated validation gates
• Building model monitoring - drift detection performance degradation alerts automated retraining triggers and full audit trails for regulatory compliance
• Owning the integration layer with Wises central ML infrastructure - aligning on boundaries so FinCrime-specific lifecycle tooling builds cleanly on shared foundations
• Maximising data science productivity - your platforms success is measured by how much time shifts from operational maintenance to improving detection performance

What do you need

• Experience building ML platform infrastructure in production - training pipelines model serving evaluation frameworks or monitoring systems. Infrastructure that other teams depend on not individual model work.
• Strong software engineering fundamentals - you build reliable well-tested maintainable systems. Python Kotlin/Java SQL.
• Experience with ML orchestration (Airflow Kubeflow or equivalent) model registries (MLflow or similar) and container-based deployment
• End-to-end understanding of the ML lifecycle - data ingestion through training packaging serving and monitoring - and knowledge of where things break
• A product mindset for internal tooling - you think about data scientists as users and build for adoption not just functionality

Nice to Have:

• Model serving at scale - latency optimisation ONNX packaging canary deployments for models
• Experience in FinCrime fraud AML or regulated environments where audit trails and model governance are non-negotiable
• Experience with model monitoring and drift detection systems in production
• Track record of migrating teams from manual ML workflows to platform-based approaches
