• Support the ML lifecycle from development through production and ongoing maintenance

Required Skills & Experience

• Strong Python experience for machine learning and data analysis
• Hands-on experience with Databricks and distributed data processing (PySpark)
• Familiarity with GCP-based ML workflows, including tools like Vertex AI and BigQuery. (Open to other cloud provider experience; i.e. AWS or Azure)
• Solid understanding of supervised and unsupervised machine learning, especially regression and clustering
• Experience with ML observability tools such as MLflow, Evidently, WhyLabs, or similar
• Experience with CI/CD practices and tools like GitHub Actions
• Ability to work with structured and unstructured data from enterprise systems

Preferred Qualifications

• Experience with pricing analytics, pricing optimization, or revenue management
• Familiarity with common ML libraries such as scikit-learn, XGBoost, PyTorch, or TensorFlow
• Exposure to feature stores, model registries, and automated retraining workflows
• Understanding of data governance, security, and compliance in ML systems

Additional Details

• Contract-to-hire opportunity
• Cloud-based, modern data and ML stack
