• This role is a strong fit for someone who cares about both the architecture behind a frontend system and the details that make a product intuitive, fast, accessible, and maintainable
• Own the technical design and delivery of complex frontend features across Ads Manager’s creative and recommendation workflows
• Translate AI-backed capabilities into interfaces that advertisers can understand, steer, and refine
• Partner with product and design to work through ambiguous requirements and make sound product and engineering tradeoffs
• Develop reusable frontend patterns and components that support a unified campaign creation experience
• Instrument experiences, evaluate results, and use experiments and product data to guide iteration
• Raise the quality of the codebase through thoughtful architecture, testing, observability, performance work, and accessibility
• Provide high-quality code reviews and technical guidance, and help other engineers grow
• Collaborate across frontend, backend, data, and machine learning systems to deliver reliable end-to-end experiences
