Responsibilities

1. Governance Strategy & Risk Mining

- Pattern Discovery: Deep dive into seller and listing behaviors to identify new abuse patterns.

- Strategy Construction: Translate insights into executable governance strategies using Rules, Thresholds, and Risk Scores. Quickly deploy tactics to mitigate sudden attacks.

- Practical Machine Learning: Develop agile, offline models (e.g., XGBoost, Random Forest, Anomaly Detection) and use Clustering to uncover organized bad-actor syndicates that simple rules might miss.

2. Metric System & Dashboard Construction

- North Star Definitions: Define and standardize core metrics for Seller and Listing Governance, such as "Low-Quality Listing Rate," "Listing Violation Rate," and "Bad seller On-boarding rate“

- Dashboarding: Build and maintain comprehensive data dashboards (using internal tools) to visualize risk trends, strategy performance, and daily operational status.

- Automated Monitoring: Design alert systems that automatically flag anomalies in the data .

3. Performance Tracking & Root Cause Analysis

- Strategy Evaluation: Continuously monitor the Precision and Recall of governance strategies. Analyze false positives to minimize impact on good sellers.

- Deep-Dive Analysis: When core metrics fluctuate (e.g., AIGC impact, GMV drops or complaint rates rise), conduct rapid root-cause analysis to determine if it is caused by governance interventions or external factors.

Minimum Qualifications

1. Individuals who are completing or have recently completed a Master's degree in Software Development, Computer Science, Computer Engineering, or a related technical discipline.

2. Expert-level SQL is a must. You can handle massive, complex datasets efficiently

3. Strong experience with BI/Dashboarding tools (e.g., Tableau, PowerBI, Metabase). You know how to design charts that tell a clear story

4. Proficient in Python (Pandas, Scikit-learn). Hands-on experience with Tree-based models (XGBoost/LightGBM) and Unsupervised Learning (Clustering) for risk scoring and segmentation

5. You can explain complex data trends to non-technical stakeholders (Operations/Policy teams)

Preferred Qualifications

1. Experience in Trust & Safety, Anti-Fraud, E-commerce Governance, or Listing Operations

2. Experience building Metric Systems from scratch: knowing how to break down a high-level goal into trackable daily indicators

3. You care about solving the business problem, not just using the most complex model
