Rapid Prototyping: Quickly develop, test, and iterate on machine learning prototypes to validate hypotheses, assess feasibility, and refine algorithms. Feature Engineering: Build and optimize large-scale consumer behavioral feature sets and feature stores that support scalable, high-performance machine learning applications. Experimentation: Design, analyze, and troubleshoot controlled experiments, including causal A/B and multivariate testing, to evaluate model effectiveness and business impact. Cross-Functional Collaboration: Partner with Product, Marketing, Sales, and other stakeholders to translate business objectives into effective ML solutions and measurable outcomes. Requirements Experience: 8+ years of experience in machine learning, with 5+ years of hands-on experience in reinforcement learning, recommendation systems, pricing algorithms, pattern recognition, artificial intelligence, or closely related fields. Machine Learning Expertise: Strong knowledge of classical ML methods, including classification, clustering, and regression, with practical experience using algorithms such as XGBoost, Random Forest, SVM, and KMeans. Reinforcement Learning: Demonstrated expertise with Contextual Bandits, Q-learning, SARSA, Bayesian approaches, Thompson Sampling, Bayesian Optimization, and related optimization techniques. Data Expertise: Strong experience working with tabular data, including sparse datasets, cardinality analysis, standardization, encoding, and feature engineering. Programming: Proficiency in Python and SQL, including Window Functions, GROUP BY, JOINs, and partitioning. ML Frameworks: Hands-on experience with machine learning libraries and frameworks such as scikit-learn, TensorFlow, and PyTorch. Experimentation: Knowledge of controlled experimentation methodologies, including causal A/B testing and multivariate testing. Problem-Solving: Strong analytical and quantitative skills, with the ability to translate complex optimization and ML challenges into practical, scalable solutions. Collaboration: Excellent communication skills and the ability to work effectively with technical and non-technical stakeholders across multiple functions. Benefits Opportunity to work on advanced machine learning, reinforcement learning, optimization, dynamic pricing, and personalization challenges. High-impact role with the opportunity to influence measurable business outcomes through AI-driven solutions. Exposure to large-scale consumer data, experimentation, and real-world ML applications. Collaborative environment with cross-functional interaction across Product, Marketing, Sales, and technical teams. Flexibility and working arrangements aligned with the partner company's policies and role requirements. Competitive compensation package based on experience, skills, and market alignment. Access to benefits and employee programs provided under the partner company's applicable employment policies.
