The role:

As a Senior ML Engineer, you'll play a central role in building the data science
behind the products — from framing new fraud, risk, and intelligence problems,
to designing and deploying ML models at scale, to helping our enterprise




customers and go-to-market teams understand and act on the insights we generate.

What you’ll do:

* Design, build, and continuously improve the ML models that power our risk and
intelligence products, and take ownership of new signals as they get scoped.
* Take a loosely defined business or customer problem and break it into a clear
data problem, articulating value, impact, and complexity before proposing a
solution.
* Build anomaly detection, fraud, and risk-modeling approaches — including
network/graph-based methods — that keep our signals accurate and resistant to
adversarial behaviour.
* Own model development, deployment, and monitoring end-to-end, partnering with
ML/data engineers on scalability, reliability, cost, and dashboards/alerting.
* Design and run experiments (A/B tests, offline customer POCs) to validate new
signals before they roll into production.
* Manage and analyse large, multi-country datasets, en
