Sr Data Scientist, Open Path

Senior Data Scientist, Open Path

At TTD, data scientists partner closely with engineering throughout the entire product lifecycle-from ideation to production and ongoing monitoring. Our data scientists are true end-to-end owners, actively involved in designing, researching, building, and delivering data-driven products that empower our clients and traders.

We are seeking a Senior Data Scientist to join the Open Path team. In this role, you will focus on developing metrics to quantify supply path efficiency and applying scalable data science modeling on large-scale datasets to improve the buying strategy.

The main job directions include:

• Develop and apply causal inference methodologies to measure the efficiency of supply paths, leveraging techniques such as double machine learning, instrumental variables, propensity scoring, and synthetic control methods.

• Define success criteria for causal measurement and ensure that model insights translate into tangible business improvements.

• Design and analyze experiments (e.g., A/B tests) to validate model performance

• Develop algorithms and models to proactively detect and interpret shifts in inventory supply paths.

• Collaborate with product managers and engineers to integrate models into existing workflows, making outputs actionable and aligned with business objectives.

• Mentor junior data scientists, fostering growth, technical excellence, and knowledge-sharing across the team.

WHO WE ARE LOOKING FOR

• Proficient in open-source languages, you have a strong passion for enhancing and expanding your technical skills. Your expertise includes hands-on development of statistical models and solutions utilizing open-source tools and cloud computing platforms. Has a deep understanding of the foundations of statistics, applied mathematics, and experimentation.

• Hands-on experience building data science solutions at scale. A track record of owning a project end-to-end (from research to production), and partnership with a cross-functional team of data scientists, engineers, and product managers to deliver advanced analytics or models.

• Possess a keen sense of data intuition and the ability to innovate in the field of metric development, control systems, causal inference, and/or statistical modeling, as evidenced by achievements like first-author publications or project successes.

WHAT YOU BRING TO THE TABLE

We do not expect you to know every technology we use when you start at TTD. What we care most about is that you can learn quickly and solve complex problems using the best tools for the job. However, we find that the most successful candidates typically come in with something like the following experience:

• BS/MS with 6+ years of experience, or PhD with 4+ years of experience, in a data science role involving the full product lifecycle from ideation to production.

• Strong background in causal inference and experimental design in production environments.

• Proficiency in Python and Scala

• Hands-on experience running large-scale workloads on distributed computing clusters (e.g., EMR, Databricks), leveraging Spark to process big datasets.

• Excellent communication skills, with the ability to engage diverse stakeholders, make architectural recommendations, drive effective execution, and measure outcomes.

• Experience in programmatic advertising and/or real-time auctions is a plus.

• Experience with deep learning is a plus.
