Senior Data Scientist - (Global Search, Consumer)

• Own the ranking stack end to end: design, build, and productionize deep neural ranking models (DCN-V2, MMoE, Two-Tower) for high-throughput, low-latency serving, from offline experimentation and evaluation through monitoring and iterative improvement.
• Lead agentic ML research: use LLM coding agents (e.g., Claude Code, Gemini) to autonomously iterate on feature engineering and Learning to Rank (LTR) architectures, design overnight experiment pipelines inspired by the auto-research paradigm, and review the outputs of hundreds of runs to identify signals quickly.
• Improve ranker quality through feature engineering and model architecture work, applying your expertise in ranking signals, feature stores, and embedding-based retrieval, and turning the latest research into production-grade systems.
• Keep production models healthy by owning monitoring for model drift, latency degradation, and feature pipeline integrity, and acting quickly when signals deviate in any market.
• Partner with Backend Engineers, Data Engineers, and Product Managers to deliver end-to-end improvements, explain ML trade-offs clearly to non-technical stakeholders, and help shape the team’s roadmap.
• Mentor junior and mid-level data scientists and set the standard for experimentation rigor, code quality, and agentic development workflows.
• A Master’s degree in Computer Science, Mathematics, Physics, or a related quantitative field (or a Bachelor’s with 6+ years of work experience), plus 4+ years as a Data Scientist or Machine Learning Engineer applying ML in high-traffic production environments.
• Production-proven experience with deep learning ranking architectures (DCN-V2, MMoE, Two-Tower), including multi-task learning, cross-feature interactions, and embedding optimization at scale, plus a solid foundation in LTR methods (pointwise, pairwise, listwise), offline metrics (NDCG, MRR), and the challenges of bridging offline metrics to online A/B outcomes.
• Proficiency with LLM coding agents and agentic CLI tools (e.g., Claude Code, Gemini) as first-class development tools for autonomous experiment generation, architecture prototyping, and rapid iteration, along with familiarity with the auto-research paradigm and comfort reviewing large volumes of generated experiment results.
• Expert Python skills across the ML ecosystem (PyTorch, TensorFlow, scikit-learn), working knowledge of SQL (dbt), GCP or AWS, and big-data processing (PySpark, Scala), and hands-on MLOps across the full lifecycle: feature stores, vector databases, model versioning and registry, Metaflow, CI/CD for ML pipelines, experiment tracking, A/B frameworks, low-latency deployment, and production monitoring for drift, latency, and data quality.
• Comfort turning broad business objectives into well-scoped data science projects, with accountability for outcomes, not just outputs.
• Experience working in cross-functional, globally distributed teams, and the ability to explain model behavior, experiment results, and trade-offs to technical and non-technical audiences.
