• Create automated validation suites in PyTest to verify model accuracy and performance for each tenant.
• Monitor model drift in production with Grafana dashboards and trigger retraining cycles.
• Document data schemas, feature stores, and model versioning procedures for cross‑team consumption.

Must-have skills

• Advanced Python for data science (pandas, scikit‑learn, PyTorch).
• Strong SQL expertise with PostgreSQL, including partitioning and indexing.
• Experience building and deploying RESTful ML services.
• Proficiency in statistical modeling and A/B testing.
• Familiarity with containerized environments (Docker, Kubernetes).

Nice to have

• Knowledge of multi‑tenant security patterns.
• Exposure to CI/CD pipelines for ML (MLflow, Kubeflow).
