Description


The machine learning team sits at the heart of our technology and delivers on the core brand promise of bringing rocket science to make advertising more rational and effective.

What you will do:

Zeta Global's technology platform supports a real-time bidding system that handles over 100 billion events every day, a reporting system that aggregates and analyzes terabytes of data in real-time, and a learning system that applies machine learning and artificial intelligence techniques to over 40 petabytes of data. These systems all work in harmony so that Zeta Global can serve the right advertisement to the right user at the right time.

The Artificial Intelligence and Machine Learning team's work sits at the core of our technology as the key decision-making agent for our systems. We research and develop the algorithms and models that make our software intelligent, as well as design, implement, and maintain the code that powers our production systems.

Some of the problems we work on include:

  • Click/Conversion Prediction: How do you use the rich data we have about users to make predictions.How do you handle conversion events that are extremely rare, such as purchasing a car. How do you deal with cold start problems.
  • Bidding Strategies: How do you translate a click or conversion score into a bid. What if it's a first price auction, second price auction, or auctions with dynamic floors. How do you take into account pacing for hour of day, day of week, and special holidays like Thanksgiving and Christmas.
  • A/B Testing: How do you ensure that the comparison will be fair. When is a result significant. How do you weigh across many different campaigns
  • Fraud Detection: Many users of the web are not human, but rather bots, crawlers, or other pieces of software that load web pages. How do you detect these "users" and protect Zeta Global from showing ads to them
  • Recommender Systems: Zeta Global dynamically tailors ads to each user, including the products shown. How do you decide which products to show in just a few milliseconds


We work with some of the most cutting-edge technologies to solve these problems, including Yarn/Hadoop (close to 2000 nodes), Spark, Hive, HBase, Airflow, Kafka and Storm. We program mostly in Scala, Java, and Python.

We are looking for talented, intellectually curious, and motivated individuals who are interested in tackling the challenging problems. We are hiring for all levels with compensation and role depending on experience.
