Machine Learning Engineer, Brand Ads

Team Overview

Brands come to our platform for scale and for a content experience where their message lands in a way that feels native and relevant. Our team builds the delivery and inventory systems that make that possible for guaranteed delivery products, owning the path from inventory forecasting and allocation through pacing, traffic strategy, delivery quality, and brand safety. We partner closely with Product, Strategy, Data Science, and cross-functional engineering teams to turn open-ended business opportunities into capabilities that scale.

You will help build and evolve the systems behind a fast-growing portfolio of brand advertising products

• Guaranteed delivery and pacing: the systems that meet committed delivery goals reliably while keeping delivery quality high.
• Inventory forecasting and allocation: the supply layer that predicts available inventory, allocates it across demand, improves utilization, and reduces waste.
• Traffic strategy and brand safety: the logic that arbitrates traffic between reservation and auction demand, and the controls that protect every impression.

Why Join Us

You will work on a brand-facing business where your systems map directly to revenue and to the experience of major advertisers, solving real inventory and delivery problems at global scale and influencing both product and technical direction.
