Unity's Advertiser Growth team leverages artificial intelligence and statistical optimization to maximize returns and reduce effort for advertisers running campaigns on the Unity ad network. Our ads reach billions of devices, and every improvement we ship directly moves outcomes for thousands of advertisers worldwide.
We are looking for a senior Machine Learning engineer to lead the design of the optimization algorithms at the heart of this mission. In this role, you will be a technical authority on how we automate campaign optimization: how bids, budgets, and targeting decisions are made to serve each advertiser's goals with minimal manual effort. You will bridge advanced quantitative methodology and large-scale engineering, working where multi-objective optimization, exploration-exploitation trade-offs, long-term value measurement, and LLM-powered agentic systems meet real-time production systems.
- Multi-objective campaign optimization: Design and ship algorithms that optimize across a variety of advertiser goals - installs, ROAS, retention, and spend efficiency - under real-world budget and marketplace constraints.
- Exploration–exploitation strategy: Design strategies (e.g.,...
