Machine Learning Engineer, Core Experimentation

Skills

About the Role

You will lead the technical direction for ML-powered experimentation and insights capabilities. You'll build production systems across ML modeling, retrieval and LLM systems, statistical methods, simulation and data pipelines, making predictions traceable, calibrated and safe enough to influence real product decisions.

Requirements

• Led ambiguous 0-to-1 production ML products
• Hands-on experience across the ML lifecycle
• Depth in LLM and retrieval systems, ranking, forecasting, causal ML, or simulation
• Strong software engineering fundamentals in Python
• Grounding in machine learning, statistics, or computer science
• Understanding of experimentation and statistical reasoning
• Ability to translate ambiguous questions into product and technical roadmaps

Responsibilities

• Set and execute the technical roadmap for Generative Insights and Predictive Experimentation
• Build cross-experiment learning systems that retrieve and synthesize historical experiments and generate hypotheses
• Develop predictive models and simulation workflows to estimate impact, segments, regression risk, and uncertainty
• Create high-quality datasets and feature or retrieval pipelines with strong lineage, privacy, and data-quality controls
• Establish rigorous evaluation via offline benchmarks, backtests, calibration, and drift monitoring
• Turn models into durable product, API, and agent workflows
• Partner with data science and product teams on experiment design, causal inference, and variance reduction
• Build reliable services and intuitive workflows for ML capabilities
• Provide technical leadership and raise the bar for production ML quality
