ML Engineer - Statistical Integrity (Financial Crime)

About

the role

We are looking for an IC3 Machine Learning Engineer to join our Risk ML and Intelligence team. In this role, you will be key to enabling the building of our machine learning models by focusing on the label side, building the integrity layer for our label platform. Every machine learning model at Wise learns from two core components: features (user signals) and labels (historical tags for activity like money laundering or fraud). If our labels are inaccurate, our models learn the wrong behavior. You will be responsible for label side quality, label monitoring, statistical integrity, and designing robust audit processes to ensure our ML infrastructure learns from clean, reliable data.

How we work: At Wise, we operate with autonomous, cross-functional teams that put the customer first. We believe strong engineers can learn and adapt across tech stacks, so our interview and pair programming evaluations are language-agnostic (focused on Python or Java), allowing you to solve complex technical problems in the environment you are most comfortable with. What will you be working on?:

• Building, scaling, and maintaining the integrity layer of our label platform for Risk ML models.
• Defining, implementing, and monitoring statistical fundamentals and key quality metrics for data and labels.
• Designing automated audit processes to evaluate and monitor label quality over time.
• Working end-to-end on machine learning model training, evaluation, and pipeline deployment.
• Collaborating closely with cross-functional partners across Risk Intelligence, Data Engineering, and Product.
