Sobre
- End-to-End Model Development: Own the entire lifecycle of fraud detection models, from data exploration and feature engineering to model training, validation, deployment, and monitoring.
- Advanced Analysis: Conduct deep-dive investigations into emerging fraud patterns and user behavior, using clustering, outlier detection, and other unsupervised techniques to uncover hidden risks.
- Experimentation: Design and execute A/B tests to measure the impact of new models, rules, and strategies on both fraud detection rates and user experience.
- Stakeholder Collaboration: Partner closely with Product, Engineering, and Operations teams to translate business needs into data science solutions and communicate complex results to non-technical audiences.
- Productionalize Models: Deploy, monitor, and maintain machine learning models in a cloud environment, ensuring high availability and performance.
- Reporting & Visualization: Build and maintain dashboards using tools like Tableau or Looker to track key performance indicators (KPIs) like fraud loss rates, false positive rates, and model performance
- Experience: 3-5 years of experience in a hands-on data science role, building and deploying machine learning models.
- Python: Expert-level Python for data analysis and modeling (pandas, scikit-learn, etc.).
- SQL: Advanced SQL skills for complex data extraction and manipulation.
- Machine Learning Modeling: Deep experience with tree-based ML models (XGBoost, CatBoost, LightGBM) and statistical models (Logistic Regression, Lasso/Ridge).
- Sampling Techniques: Strong understanding of sampling techniques for handling highly imbalanced datasets.
- Unsupervised Learning: Practical experience with clustering and outlier detection techniques (e.g., K-Means, K Nearest Neighbors, Isolation Forest).
- Model Lifecycle & Cloud: Proven experience with the full modeling lifecycle, including model deployment, monitoring, and maintenance on a cloud platform like GCP, AWS, or Azure.
- Communication: Excellent stakeholder management and communication skills, with a demonstrated ability to explain complex technical concepts to diverse audiences.
- Analytical Rigor: A solid foundation in statistics and experience designing and analyzing A/B tests.
- Communication: Advanced English level
- Domain Experience: Direct experience in a FinTech, payments, or risk/fraud-focused role.
- MLOps: Hands-on MLOps experience (e.g., CI/CD for models, versioning, automated retraining).
- Model Explainability: Knowledge of model explainability frameworks like SHAP or LIME.
- GCP / Vertex AI: Experience with Google Cloud Platform (GCP), especially Vertex AI.
- Competitive salary
- Initial stock options grant
- Annual performance bonus
- Health, dental, and vision plans
- Remote work environment, although we have offices in Miami and México City and would love to work in hybrid model if you are up to it.
- Continuous learning opportunities
- Unlimited PTO
- Paid parental leave
- Empowering opportunities for growth in a dynamic entrepreneurial environment
