• Scale our ML platform — feature stores, training pipelines, model versioning, A/B experimentation — to support multiple model families running in production simultaneously
• Drive sub-10ms inference at high QPS through model optimization (ONNX), efficient serving, and latency-aware architecture decisions
• Own end-to-end ML workflows from data ingestion through monitoring: drift detection, shadow scoring, A/B tests, and automated retraining triggers
