Sr. Machine Learning Engineer

What you'll do:

• Write production Python that powers real-time bidding, model training, and campaign optimization
• Train, deploy, and monitor ML models that decide which ads to show, when, and at what price: millions of bid decisions per second
• Build and improve our incrementality measurement systems: helping advertisers understand the true causal lift of their CTV spend

What we're looking for:

• Strong production Python skills: you write code that runs in prod, not just notebooks
• Solid statistics and ML fundamentals: you can reason about experiment design, model evaluation, and when simpler approaches beat complex ones
• Familiarity with modern AI tools and good judgment about where they add value

Nice-to-Haves:

• Teaching experience
• Causal inference: uplift modeling, synthetic controls, difference-in-differences, or incrementality testing
