Senior Machine Learning Engineer

At Groupon, we’re rewriting what it means to be an AI-First company. Just months removed from a major transformation, we’re scaling up with intensity and putting AI at the heart of our business solutions. Join our nimble, high-impact team as the technical owner for next-generation recommendation and search models—help shape a local experiences marketplace used by millions. Lead the full ML model lifecycle—feature engineering, model design, training, deployment, monitoring, and ongoing improvement. Architect and implement scalable ranking, retrieval, and personalization models using state-of-the-art ML frameworks (e.g., PyTorch, TensorFlow). Build robust, production-ready ML data pipelines and infrastructure (Python, GCP, Docker/Kubernetes). Integrate ML models into high-traffic distributed systems; ensure observability, CI/CD, and real-time performance. Collaborate closely with Product and Data Engineering to deeply understand business needs and translate them into measurable user impact. Set technical standards and mentor less-experienced colleagues as an emerging ML leader in our scale-up environment. Experiment with advanced techniques (embeddings, deep learning, reinforcement learning) and champion an evidence-driven, AI-first culture.
