Description

  • Own and operate machine learning models in production, including monitoring, debugging, and iterative improvement.
  • Develop, train, and optimize models used in real-time or near-real-time bidding and decisioning systems.
  • Collaborate with product, engineering, and business stakeholders to clarify ambiguous problems, define success metrics, and translate business needs into technical solutions.
  • Design and implement feature engineering pipelines that balance model performance, latency, and maintainability.
  • Write production-quality Python code and work with engineering on deployment, CI/CD, and system design.

  • Experience deploying, maintaining, or owning ML models beyond experimentation (APIs, batch jobs, or streaming systems).
  • Comfort working across development, staging, and production environments and operating with limited guidance.
  • Experience with feature engineering for tabular data and designing data engineering/ETL pipelines (preferred).
  • Experience with model monitoring, evaluation, debugging in production and improving model latency, reliability, or cost (preferred).
  • Prior technical leadership or mentoring experience and experience at smaller companies/small teams where you wore multiple hats (preferred).
  • Familiarity with Airflow, Kubernetes, or cloud infrastructure (preferred).

Benefits
