• Identify architectural bottlenecks, technical debt, and scaling risks, and proactively drive solutions across organizational boundaries
• Stay current with industry trends in commerce advertising, recommendation systems, retrieval and ranking architectures, and Shopping Ads optimization

Qualifications

• 8+ years of software engineering or ML engineering experience, including experience leading engineering teams
• Strong hands-on technical depth in ads ranking, retrieval, targeting, recommendation systems, engagement modeling, or ML-driven optimization systems
• Experience building and operating large-scale distributed systems or ML systems in production
• Proven ability to operate as a technical lead manager (TLM), driving architecture and execution while managing and developing engineers
• Experience partnering with Product, ML Platform, Ads Serving, Data Science, and cross-functional stakeholders to deliver complex initiatives
• Strong systems thinking with the ability to balance technical quality, execution speed, scalability, and operational reliability
• Excellent debugging, prioritization, and execution skills in fast-moving production environments
• Strong communication and leadership skills with the ability to align teams around technical strategy and business priorities
