Lead ML Engineer developing scalable data pipelines and ML systems for Newfold Digital. Collaborate with cross-functional teams using Python, SQL, and cloud ML platforms in an applied ML environment.
Responsibilities
Partner with the business to translate requirements into clear problem statements, KPIs, and experiment plans (A/B, holdout, backtests)
Design data & ML architectures on lakehouse /warehouse stacks (e.g., Oracle Exadata, Spark/Databricks; Snowflake / BigQuery /Redshift with open table formats like Iceberg/Delta/Hudi or equivalent)
Build pipelines for ingestion, feature engineering, and training (batch & streaming) using Python + SQL with orchestration (Airflow/Prefect/Dagster)
Model using scikit-learn/XGBoost/LightGBM and PyTorch/TensorFlow; manage experiments and lineage
Serve & operate models on a major cloud ML platform (Azure ML, SageMaker or Vertex AI), with CI/CD, canary/blue-green, and rollback guardrails
Monitor & improve: implement data/model quality and drift monitoring, alerting, and dashboards; close the loop with BI (Power BI/Tableau/Looker)
Document & review: author concise design docs and run technical reviews; mentor engineers; champion responsible AI practices
Requirements
8+ years in applied ML & data engineering (3+ years leading delivery of production ML systems)
Python expert with production-grade SQL; strong with pandas/Polars, scikit-learn, and one of: XGBoost/LightGBM
Fluency in core ML toolkits including TensorFlow, PyTorch, scikit-learn, and familiarity with Hugging Face or equivalent frameworks
Proven record of constructing and maintaining scalable data pipelines—both batch and streaming—for model training and deployment
Data platforms: hands-on with one of: Oracle ExaData, Spark/Databricks, or Snowflake, BigQuery/Redshift or equivalent; comfortable with open table formats (Iceberg/Delta/Hudi)
Orchestration: real projects using one of Airflow, Prefect, or Dagster
Cloud ML platform: production deployments on one of SageMaker, Vertex AI, or Azure ML (pipelines, endpoints, registries)
MLOps: CI/CD for ML, experiment tracking, model registry, observability (latency, errors), and data/model drift monitoring
Communication: ability to frame trade-offs and influence cross-functional partners; crisp writing of design/decision docs
