This role focuses on translating well-scoped business problems into reliable ML systems, partnering closely with engineering, data, and product teams to move models from experimentation into production with appropriate monitoring and governance.<\/p>\n\n\n\n<p>This role exists because modern software products increasingly rely on ML-driven capabilities\u2014such as personalization, forecasting, anomaly detection, search relevance, NLP automation, and decision support\u2014that require specialized methods beyond traditional software engineering.
