The Performance Automation team is dedicated to developing optimization tools that enhance our clients' advertising campaign outcomes, ensuring they meet or surpass their Key Performance Indicators (KPIs).

You will be working on enhancing machine learning model development; creating the tools and frameworks that allow for quicker iteration and refinement of models by data scientists, from creating ETLs that process petabytes of data to experimenting with novel model training architectures. You will be responsible for integrating models in our bidding infrastructure, where low latency and high performance are of paramount importance;

your code will be running millions of times per second on datacenters across the entire globe.

You will be also working on developing and improving debugging and analytical tools for monitoring and adjusting the bidding system in real‑time. Utilize these tools to quickly identify and address any issues, improving campaign efficiency and ensuring effective use of budgets and resources.

Our Software Engineer II team members will participate actively in all aspects of designing, building, and delivering products for our clients.

We have dozens of mission‑focused teams working across a wide spectrum of technological challenges. You will have the opportunity, depending on your interests and aptitude, to work on large‑scale distributed systems coordinating thousands of servers in cloud and physical data centers around the world, petabyte‑scale data challenges, machine learning, advanced visualizations, and interactive user interfaces – to name a few.
