Principal Research Scientist at Yahoo | LAYIQ

Lead the research, architectural design, and production deployment of large-scale algorithms for budget pacing, bid optimization, and marketplace supply/demand balancing.
Architect and spearhead the implementation of agentic AI workflows—utilizing AI coding agents, automated experiment orchestration, and agent-driven validation to dramatically accelerate research-to-production iteration velocity.
Provide technical strategy and long-term vision for the DSP optimization ecosystem in close alignment with business and engineering leadership.
Apply control theory, convex/stochastic optimization, and machine learning to solve complex, real-time marketplace dynamics under signal uncertainty.
Direct AI-assisted code refactoring, automated testing suite generation, and LLM-driven research synthesis using modern tools (e.g., Cursor, GitHub Copilot, Gemini, Claude, ChatGPT) to elevate team engineering standards.
Own multi-quarter research initiatives from mathematical formulation through production rollout, establishing rigorous metrics and evaluation frameworks.
Partner closely with engineering and product management teams to ensure algorithmic designs execute seamlessly at scale.
Mentor senior scientists and engineers, setting technical excellence standards and fostering an AI-forward research culture.
Communicate technical strategy, experimental results, and architectural choices clearly to executive and cross-functional partners.
