The Mission

The primary mission is to drive the machine learning (ML) and deep learning (DL) research agenda for the client-classification engine and adjacent transaction risk control/anti-fraud scenarios across the trading chain. The role involves taking the best ideas to production—safely, quickly, and cost-effectively. You will own the end-to-end experiment loop, from hypothesis to backtest, calibration, and monitored rollout, ensuring that routing and control decisions improve broker P&L, stability, and abuse prevention.

What You’ll Do

Essential (Core) Responsibilities:
- Serve as the key owner for modeling research execution: translate business and user questions into measurable data solutions, collaborating with analysts and engineers to build, test, and iterate.
- Explore and apply ML/DL models: experiment with a variety of algorithms to solve practical integrity and classification problems.
- Address related challenges: work on user behavior modeling, fraud/anomaly detection, reputation/risk scoring, or abuse prevention, depending on business needs.
- Own the experiment loop: design fair, time-aware evaluation strategies; conduct robust backtesting and validation; clearly report findings and next steps.
- Partner for production: collaborate with engineers to deploy models safely, monitor their health, and set up retraining or recalibration triggers.
- Communicate clearly: write concise design documents and experiment summaries that are actionable for both technical and business stakeholders.

Advanced (Plus) Skills:
- Deep learning and time-series: experience with neural network models (e.g., LSTM, GRU, Transformers) or advanced architectures for temporal/user sequence data.
- Representation learning: proficiency with embeddings, autoencoders, or other feature-learning approaches to enhance prediction or personalization.
- Working with imperfect data: adept at handling noisy, incomplete, or partially labeled data (e.g., semi-supervised or weak supervision).
- Experimentation at scale: hands-on experience with tuning, validation, and reproducibility on large datasets or distributed compute environments (e.g., Spark/Databricks, MLflow).
- Business/context awareness: ability to connect modeling choices to real-world metrics and user/business value.

Minimum Qualifications

- 5+ years of experience in Data Science, ML, or DL, with a proven track record of using data and models to solve practical business or user problems.
- Strong proficiency in Python and SQL, with the ability to write clean, reproducible analysis code in notebooks or scripts.
- Hands-on experience with at least one ML or DL library (such as scikit-learn, PyTorch, or TensorFlow).
- Solid understanding of experiment design fundamentals, including careful validation, fair metrics, and awareness of data pitfalls.
- Effective communication skills, with the ability to summarize findings and decisions for both technical and non-technical partners.

Nice to Have

- Experience in integrity, fraud, abuse, personalization, recommendations, search, ads, or growth analytics.
- Familiarity with cloud analytics stacks (Spark, Databricks, MLflow) or large-scale experimentation.
- Exposure to classification, anomaly detection, or user segmentation in any domain.
