Build optimization algorithms that improve ad yields and efficiencies. Some of the models we developed over the last year are CTR (Click Through Rate) and CVR (Conversion Rate) Prediction models for the ads. You will not only work on improving existing optimization Machine Learning models but also develop new models from scratch for a variety of upcoming product launches.
Build and improve Machine Learning algorithms that match ads to the most relevant users. Some algorithms/techniques are Logistic Regression, Gradient Boosted Decision Trees and Deep Learning methods,
Be involved in all phases of modeling, such as ideation, offline modeling, online implementation,experimentation,deployment and post-launch monitoring/measurements.
This role will have a lot of overlap with other Machine Learning Engineer roles but will differ in a couple of areas. First is that you will work mainly on offline modeling and rely on engineers to productionize your models. Secondly, you will have a keen interest in designing and running experiments.
