production-oriented settings using Python, SQL, and ML frameworks.

- Building real-time or near-real-time ML systems for recommendations, pricing, bidding, or similar use cases.

- Working with data warehouse technologies (Redshift, Snowflake, BigQuery) and building/managing data pipelines (dbt, Airflow, Spark).

- Strong foundation in statistics, probability, experiment design, and machine learning theory.

- Experience working with ML platforms and infrastructure (SageMaker, Spark, Ray,

MLflow, or equivalent).

- Comfortable doing software engineering when needed-writing application code in Python/Scala/Java, contributing to APIs, containerizing services (Docker, Kubernetes), or building CI/CD for model deployments.

- Excellent communication skills-effective with both technical and non-technical audiences.
