Senior Data Scientist

Architecting the Future of Recommendations

Join Taboola in Downtown Los Angeles to lead the development of ranking algorithms that power the world’s leading performance ad platform. This role invites you to move beyond manual coding by embracing agentic AI systems to influence the experience of over 600 million daily users. You’ll be responsible for the full lifecycle of predictive models, turning complex data into revenue-driving outcomes.

A Modern, AI-First Workflow

Taboola is looking for candidates who can master 'vibe coding'—using tools like Cursor, Claude, and GitHub Copilot to prototype and deploy ML systems with unprecedented speed. Your primary focus will be on 'Harness Engineering,' where you’ll build the evaluation frameworks and safety guardrails necessary to ship high-quality code. The tech stack is deep, involving Python, Java, and ML frameworks like PyTorch and Spark, all managed through a system-architecture mindset.

Growth and Scale

You will navigate distributed systems like Hadoop and Kafka to process massive datasets, collaborating with international teams to bridge the gap between experimental AI and production-grade software. This is an ideal opportunity for a data scientist who wants to define how AI-assisted development works at the enterprise level while enjoying a hybrid work environment and comprehensive benefits.
