• Solid understanding of browser rendering, asset optimization, and how to minimize latency in third-party environments
• Proven ability to lead feature development from ideation through deployment, including writing design docs and performing code reviews
• Practical experience building consumer ad products from end-to-end, or building 'native' ad formats

• Experience designing clean, extensible APIs that serve both internal and external stakeholders
