Smadex is a performance advertising engine for mobile apps, enabling the world's leading marketers to grow across Mobile and Connected TV (CTV). Headquartered in Barcelona, with teams across the Americas, EMEA, and APAC, Smadex is a business unit of Entravision (NYSE: EVC).
Our mission is to continue to improve our ad-tech platform, especially the core of it, our algorithms, to help our clients achieve their programmatic advertising campaign goals. We want to give our employees a job they’ll love, where they will be challenged to improve results through real-life engineering and data analysis and where everyone’s implication has an impact.
Ad-tech is one of the most demanding environments for machine learning. As a Data Scientist embedded within our Machine Learning team , your mission is to bridge the gap between theoretical model design and real-world production reality. You will be the analytical anchor dedicated to ensuring the performance, interpretability and stability of our core Deep Neural Networks models within our high-frequency,



complex auction ecosystem with millions of ad requests processed every second.
We are looking for a deeply analytical individual with very strong ML expertise —someone who isn't satisfied with "it works," but needs to understand the system at a fundamental level. You will apply scientific rigor to drive measurable improvements in our live bidding performance.
Model Understanding and Training: To do so, you will autonomously formulate different hypotheses and validate them by performing the appropriate data analyses and by training different models to compare the results.
Deep-Dive Auction Dynamics Analysis: Conduct in-depth analysis of model behavior in the live auctioned environment to understand how our algorithms and models interact with market dynamics.
Experimentation: Design and analyze experiments, A/B testing, to validate hypotheses regarding bidding strategies and model improvements.
