Senior ML Scientist / ML Engineer, Fraud Detection | Remote, US | $140,000 to $210,000 base + bonus + equity

Own models that decide the majority of traffic on a platform processing billions of e-commerce transactions a year, from experiment design through to production.

The Company
An AI-driven fraud prevention platform for e-commerce. It analyses purchases in real time and financially guarantees approved orders, so ML performance drives the business directly. The ML organisation runs on mature in-house infrastructure with strong engineering and scientific rigour.

The Role

  • Design new ensemble architectures that combine multiple fraud models into a stronger decision layer.
  • Build offline evaluation methodology that reliably predicts production performance.
  • Own experimentation end to end, from hypothesis to production deployment.
  • Prototype and integrate new ML techniques and infrastructure to improve detection and scalability.
  • Build pipeline components that increase the team's experimentation speed.
  • Partner with Product, Engineering and Risk to turn business problems into ML solutions.

What We're Looking For

  • 4 to 6+ years building ML in production environments.
  • Hands-on model development: designing experiments and building solutions from first principles in response to a business problem.
  • Strong ML theory and statistical evaluation, including offline evaluation design.
  • Python, SQL and Spark in a distributed computing environment.
  • Senior and Staff level candidates are welcome. Applied Scientist and ML Scientist backgrounds are a strong fit.
  • Nice to have: a PhD or Master's in CS or Statistics, and payments or fraud domain experience.

What's On Offer

  • Base of $140,000 to $210,000 depending on location and level, plus up to 10% annual bonus and stock options.
  • Remote from anywhere in the US, on US time zones, with in-person time once a year.
  • Pod-style teams that own their services and models end to end.
  • Unlimited PTO, 401k match, 12 weeks' paid parental leave and a learning budget.
  • US citizens and green card holders only. Visa sponsorship is not available.
