Introduction to team:

The Search Product & Optimization team at Expedia Group sits within the Marketing division and is responsible for the algorithmic intelligence behind our global marketing investments. We operate in a fast-paced and dynamic environment, participating in millions of auctions daily across Search, Metasearch and Social platforms. Our mission is to build scalable, data-driven systems that optimize how we acquire traffic. We are moving beyond traditional analytics to develop automated decisioning systems that dynamically allocate investment to maximize business value. We operate under a build & scale philosophy, creating solutions that adapt to a rapidly evolving search marketing landscape.

In this role, you will:

  • Design and implement machine learning models to optimize bidding strategies (e.g., Cost-Per-Click, Target ROAS, Target CPA) and investment allocation across diverse marketing channels.
  • Develop methodologies to measure elasticity (how performance changes as spend scales) to help us answer granular capital allocation questions.
  • Write clean, efficient and reproducible Python code. You will partner with Machine Learning Engineers to deploy your models into production environments, ensuring they are robust and scalable.
  • Contribute to the development of feedback loops and control mechanisms that allow our bidding systems to self-correct and adapt to market volatility or competitor changes.
  • Design and analyze A/B experiments to validate model performance and inform strategic decisions.
  • Translate mathematical concepts into clear insights for business partners. You will help frame vague business problems into concrete analytical tasks and define the objective functions that our models solve for.

Experience & Qualifications:

  • Bachelor or Master’s degree in a quantitative field (Computer Science, Statistics, Mathematics, etc.) or equivalent practical experience.
  • 2+ years of professional experience applying Machine Learning to real-world business problems.
  • Strong Python proficiency in writing production-quality code and using libraries like pandas, scikit-learn, numpy.
  • Advanced SQL ability to write complex queries to handle large-scale datasets.
  • Solid understanding of regression (GLMs), optimization techniques, time-series forecasting and probability theory.
  • A strong interest in AdTech, Bidding Markets, Game Theory, or Control Systems. You are curious about how auctions work and how to optimize within them.
  • Comfortable working with ambiguity. You can take a high-level goal and break it down into a solvable mathematical problem.
