The mission
Drive the ML/DL research agenda for our client-classification engine and adjacent
transaction risk control/anti-fraud scenarios across the trading chain. Take the best
ideas to production—safely, fast, and cost-effectively. You’ll own the end-to-end
experiment loop, from hypothesis → backtest → calibration → monitored rollout, so our
routing and control decisions improve broker P&L, stability, and abuse prevention.

What You’ll Do
Essential (Core)
• Be the key owner for modeling research execution: turn business and user
questions into measurable data solutions; collaborate 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.
• Tackle related challenges: work on areas like 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 ship models safely,
monitor health, and set up retraining or recalibration triggers.
• Communicate clearly: write concise design docs and experiment summaries
that both technical and business stakeholders can act on.
Advanced (Plus)
• Deep learning and time-series: comfortable exploring neural network models
(e.g., LSTM, GRU, Transformers) or advanced architectures for temporal/user
sequence data.
• Representation learning: experience with embeddings, autoencoders, or other
feature-learning approaches to improve prediction or personalization.
• Working with imperfect data: familiar with handling noisy, incomplete, or
partially labeled data (e.g., semi-supervised or weak supervision).
• Experimentation at scale: hands-on with tuning, validation, and reproducibility
on large datasets or distributed compute (e.g., Spark/Databricks, MLflow).
• Business/context awareness: able to connect modeling choices to real-world
metrics and user/business value.
Minimum qualifications
• 5+ years in Data Science/ML/DL, with a track record of using data and models to
solve practical business or user problems.
• Strong Python and SQL; able to write clean, reproducible analysis code in
notebooks or scripts.
• Hands-on with at least one ML or DL library (scikit-learn, PyTorch, TensorFlow).
• Solid experiment design fundamentals: careful validation, fair metrics, and an
eye for avoiding data pitfalls.
• Effective communicator: able 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.
