  • Foster a strong partnership between our fraud investigators and the product team to develop solutions that leverage the expertise of fraud prevention specialists.

  • Not only meet the requirements set by regulators and auditors but also surpass their expectations.

  • We are looking for someone who will help maintain our existing machine learning algorithms, while helping to make them better and develop new intelligence to stop fraudsters.


Here’s how you’ll be contributing:

We are seeking a highly motivated Lead Data Scientist to join our Fraud Risk Team. In this role, you will level up the intelligence and maintain and refine existing models, develop new features, and create new intelligence to reduce the impact on good customers.

Further you will help grow our data science team in space.

Key Responsibilities:

Model Maintenance and Improvement:

  • Maintain and optimise existing risk models to ensure their accuracy and reliability.
  • Continuously monitor model performance and implement improvements based on feedback and testing.

Innovate and Develop:

  • Lead the development and deployment of machine learning models, features and help deploy intelligence to production

Data Analysis & Intelligence Creation:

  • Conduct thorough data analysis to identify trends, patterns, and anomalies that can aid in risk mitigation.
  • Develop actionable intelligence and insights to inform the Fraud Risk Team's strategies.

Collaboration & Communication:

  • Work closely with the Fraud Risk Team to understand business processes and risk factors.
  • Communicate complex data findings and insights effectively to non-technical stakeholders.

Risk Reduction Initiatives:

  • Identify opportunities to reduce the impact of risks on good customers through data-driven strategies and interventions.
  • Develop and test strategies to balance risk mitigation with customer satisfaction.

Documentation & Reporting:

  • Document the development and maintenance processes for models and features.
  • Prepare and present detailed reports and dashboards that reflect risk assessment outcomes and model performance.


A bit about you:

  • Proven track record of deploying models from scratch, including data preprocessing, feature engineering, model selection, evaluation, and monitoring.

  • Strong Python knowledge. Ability to read through code, especially Java. Demonstrable experience collaborating with engineering on services;

  • Experience with statistical analysis and good presentation skills to drive insight into action;

  • A strong product mindset with the ability to work independently in a cross-functional and cross-team environment;

  • Good communication skills and ability to get the point across to non-technical individuals;

  • Strong problem solving skills with the ability to help refine problem statements and figure out how to solve them.

Some extra skills that are great (but not essential):

  • Experience on working with non supervised algorithms

  • Prior experience in the fraud domain and a strong understanding of fraud detection techniques.

We’re people without borders — without judgement or prejudice, too. We want to work with the best people, no matter their background. So if you’re passionate about learning new things and keen to join our mission, you’ll fit right in.

Also, qualifications aren’t that important to us. If you’ve got great experience, and you’re great at articulating your thinking, we’d like to hear from you.

And because we believe that diverse teams build better products, we’d especially love to hear from you if you’re from an under-represented demographic.
