Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of Moloco as an employer.

What you need

  • Ph.D. in computer science, statistics, operations research, economics, or a related quantitative field, plus 2+ years of industry experience, or 5+ years of industry experience solving large-scale ML, optimization, or systems problems without one
  • Strong applied statistics and causal reasoning skills
  • Fluency in Python and SQL against large datasets (Spark, BigQuery, or equivalent)
  • Experience owning a model or algorithm in production
  • Clear written English

Nice to have

  • Experience in ads, recommendation, search ranking, marketplaces, or real-time auctions
  • Knowledge of probability calibration, delayed feedback, or selection bias in logged-bandit data
  • Experience with CTV, attribution modeling, or incrementality measurement
  • Familiarity with PyTorch or TensorFlow applied to tabular or sequential production data at scale

Worth weighing

  • The role requires a strong emphasis on communication and collaboration with various teams, which may not suit those preferring independent research work.
  • The distinction between Senior and Staff roles is based on demonstrated scope rather than years of experience, which may affect career progression expectations.
