  • Implement and maintain:
  • MLflow (experiments, model registry)
  • CI/CD pipelines for ML
  • Champion/Challenger model frameworks
  • Enable:
  • Controlled rollouts (shadow, advisory, active scoring)
  • Versioned feature and model deployments
  • Design and consume features from batch and low‑latency feature stores
  • Collaborate on data quality validation, schema contracts, drift detection (feature + score)
  • Implement feature drift detection, model performance monitoring, SLA and freshness validation
  • Support replay and recovery using idempotent design patterns

Requirements

  • 3–5 years hands‑on experience as a Machine Learning Engineer
  • Strong experience taking ML models from development to production
  • Programming: Python, PySpark
